Genetic diversity of common beans as impacted on by farmer variety selection for the management of bean root rots in south western Uganda
•
1 like•416 views
Farmers in southwestern Uganda grow bean mixtures to manage bean root rots caused by Pythium fungi. A survey found farmers recognize root rot symptoms and use mixtures for disease insurance. Analysis of collected bean samples found two genetic groups, with the Mesoamerican group showing more resistance to root rots. While morphological diversity was higher in the Andean group, molecular analysis found greater diversity in the susceptible Mesoamerican varieties preferred by farmers for their root rot resistance. The study indicates farmer selection practices maintain genetic diversity needed to manage this key disease.

![GENETIC DIVERSITY OF COMMON BEANS AS IMPACTED ON BY FARMER VARIETY SELECTION FOR THE MANAGEMENT OF BEAN ROOT ROTS IN SOUTH WESTERN UGANDA S. Buah 1 , P. Okori 2 and R. Buruchara 1 1 International Center for Tropical Agriculture (CIAT), Kawanda, P.O. Box 6247, Kampala, Uganda; 2 Makerere University, Faculty of Agriculture, P.O. Box 7062, Kampala, Uganda. Introduction Common bean is the world's most important food legume with an average consumption of 66 kg per person per year in Eastern Africa. Uganda is the second largest consumer after Rwanda. However, production of the crop is curtailed by several biotic and abiotic constraints. Among the biotic constraints, Pythium root rot caused by a complex of Pythium species, is one of the most devastating diseases, causing yield losses of up to 100% in certain seasons. Mixtures of beans have been cultivated and managed by farmers from season to season for various reasons including protection against total crop losses. This practice has resulted in a broad array of phenotypically different seed and plant types. However, the impact of root rots on the genetic diversity of these mixtures is not well understood. The objectives of this study were therefore to 1) understand farmer practices of using bean mixtures in bean root rot management; 2) analyze genetic diversity associated with bean mixtures in South-western Uganda. Materials and Methods Diagnostic Survey : This was conducted to collect bean samples and information on mixtures representing various landraces from Kabale and Kisoro districts (Figure 1). Fifty two farmers and 28 traders/stockists were randomly selected, interviewed and a 1kg of their bean seeds collected. Morphological characterisation: Collected samples were sorted out according to seed phenotypes and were morphologically characterised in the field using the IBPGR’s (1982) descriptor list for common bean. All the cultigens were then screened against P. ultimum var. ultimum in the screen house. Molecular characterisation: Due to a large number of cultigens involved, 100 samples representing all the morpho-agronomic clusters were randomly selected and assessed for genetic variability using Simple Sequence Repeats. A total of 6 SSR primers were used to amplify specific PCR products. Phaseolin, the major storage protein of common bean, was analysed using primers that differentiate “S” phaseolin gene family from the “T” phaseolin types. Figure 3: Genetic relationships among common beans based on 6 SSR loci ,[object Object],[object Object],[object Object],[object Object],Figure 1: The location and number of mixtures (in red) collected from Kabale and Kisoro districts. Figure 2: Morphological relationships among bean cultigens based on 8 traits ,[object Object],[object Object],[object Object],[object Object],Results Farmer indigenous knowledge Over 60% of bean varieties were discovered to be locally conserved within the area either through savings from previous harvests or buying known seed types from local markets. The most important reason for using bean mixtures was insurance against unforeseen weather changes or pest and diseases. More than 78% of the respondents recognised and described symptoms of root rots on their farms. Morphological characterisation Cluster analysis based on morphological traits revealed two distinct groups corresponding to Andean (41%) and Mesoamerican (59%) gene pools (Figure 2). Overall average disease score for the Andean group was 5.7 compared to 4.7 for the Mesoamerican group. Only 16% of cultigens were resistant to Pythium, 58% were moderately resistant. About70% of resistance found in Kisoro district. Molecular Characterisation SSR analysis showed a higher diversity in the susceptible Andean genotypes than in the resistant Mesoamerican genotypes. Bootstrap analysis divided the cultigens into 2 clusters corresponding to Mesoamerican and Andean gene pools (Figure 3). The Andean cluster had T-Type phaseolin, whereas the Mesoamerican group had predominantly S-Type phaseolin which is characteristic of that gene pool. A hierarchical AMOVA revealed significant differentiation within populations at the sub-counties ( P < 0.001, but no significant genetic variability between the districts of Kabale and Kisoro ( P > 0.05).](https://image.slidesharecdn.com/posterginessbuah-100609161701-phpapp01/85/Genetic-diversity-of-common-beans-as-impacted-on-by-farmer-variety-selection-for-the-management-of-bean-root-rots-in-south-western-Uganda-1-320.jpg)

Rice production in agriculture biotechnology
Rice is a staple food for over half the world's population and provides over a quarter of dietary energy and protein in developing countries. Modern farming technologies like semi-dwarf and nitrogen responsive varieties have led to 84% of rice production growth. Over 2000 modern varieties have been commercially released in Asia over 40 years, gradually incorporating biotic and abiotic stress resistances. Agricultural biotechnology can increase crop productivity, improve nutrition, and broaden stress tolerance in rice. Molecular markers and transgenic technologies allow introduction of traits like herbicide and stress resistance and enhanced nutrition into rice. Golden rice was developed using genes from daffodil and bacteria to biosynthesize beta-carotene, a vitamin A precursor, addressing deficiencies

Parthenocarpy, or fruit development without fertilization, is an important trait in vegetable crops. It allows for seedless fruit production and stability in adverse conditions. Parthenocarpy can be genetic or induced artificially through plant hormones, breeding, or biotechnology. Researchers have used techniques like gene regulation, radiation, plant growth regulators, and hybridization to develop new parthenocarpic lines and varieties in crops like cucumber, tomato, eggplant, and watermelon. While parthenocarpy provides benefits, it can also result in misshapen fruit and challenges maintaining the trait in subsequent generations. Future work aims to create more stable, high-yielding parthenocarpic crops.Terminator gene technology & its applications in crop improvement

This study aimed to observe the response of 34 rice accessions to attack by sugarcane borer (Diatraea saccharalis Fabr., 1794) and to analyze the genetic diversity of these accessions by microsatellite markers. Twenty larvae were placed on the leaf sheaths of rice plants. At 30 days after infestation the rice plants at ground level were taken to the laboratory where the signs of borer attack, external and internal diameter of the stem and weight of surviving larvae were determined. For the molecular analysis of rice acces- sions, 24 microsatellite markers were used. The results of the morphological traits of the rice plant, response of the plant to insect attack, development of the sugarcane borer larvae and molecular data, indicated a genotypic variation. The accessions that most favored larval survival were IAC 47 and Ti Ho Hung. Larvae with highest weight (0.0986 g and 0.0862 g) and the largest internal diameters of the rice stem (3.18 mm) were found in land races “Canela de Ferro” (rust colored stem) and all these “Canela de Ferro” accessions also remained genetically grouped. The most tolerant materials, based on the ability to produce new tillers after larval infestation were, Chiang an Tsao Pai Ku and IR 40 which remained morphological and genetically grouped. The results of this study indicate that all the traits and molecular analyses were able to separate the accessions of rice into different groups in relation to resistance to the sugarcane borer. These materials can be used as donor sources in breeding for genetic resistance to sugarcane borers and can be used as donors to amplify the genetic base of Brazilian rice.
Incidence and toxigenicity of fungi contaminating sorghum from Nigeria
Each Agro ecological zone was transversely delineated into 5 districts and five villages (at least 20 Km from each other) called “locations” were selected in each district. In each district, Sorghum grains in stores, bunches in the field and sorghum grains in the market were sampled from five locations, each approximately 20 km from the previous sampling location. The mycological analytical procedures were performed under aseptic condition. Plates were counted for fungal colonies using a colony counter and the number of fungal colonies per gram of sample was calculated as CFU/g. The fungi species were isolated and subsequently identified using MEA/CYA media for Aspergillus and Penicillium species and PDA for the fusarium species Toxigenicity studies on strains representing species of Aspergillus, Penicillium, Fusarium was carried out to determine their ability to produce aflatoxin B1 (AFB1); aflatoxin B2 (AFB2); aflatoxin G1 (AFG1); aflatoxin G2 (AFG2); OTA, ZEN, DON and FB1. A total of 701 isolates were recorded which consist of 67 confirmed fungal strains. Aspergillus species formed the majority with 346(49.6%) followed by the Fusarium species with 186(26.7%) then Penicillium species with 102(14.6%) while others such as Cuvularia, Phoma, Alternaria, Rhizormucor constitutes 67 (9.0% )strains of the total population.

Incidence and toxigenicity of fungi contaminating sorghum from Nigeria
Each Agro ecological zone was transversely delineated into 5 districts and five villages (at least 20 Km from each other) called “locations” were selected in each district. In each district, Sorghum grains in stores, bunches in the field and sorghum grains in the market were sampled from five locations, each approximately 20 km from the previous sampling location. The mycological analytical procedures were performed under aseptic condition. Plates were counted for fungal colonies using a colony counter and the number of fungal colonies per gram of sample was calculated as CFU/g. The fungi species were isolated and subsequently identified using MEA/CYA media for Aspergillus and Penicillium species and PDA for the fusarium species Toxigenicity studies on strains representing species of Aspergillus, Penicillium, Fusarium was carried out to determine their ability to produce aflatoxin B1 (AFB1); aflatoxin B2 (AFB2); aflatoxin G1 (AFG1); aflatoxin G2 (AFG2); OTA, ZEN, DON and FB1. A total of 701 isolates were recorded which consist of 67 confirmed fungal strains. Aspergillus species formed the majority with 346(49.6%) followed by the Fusarium species with 186(26.7%) then Penicillium species with 102(14.6%) while others such as Cuvularia, Phoma, Alternaria, Rhizormucor constitutes 67 (9.0% )strains of the total population.
Poster101: Bean root rot management in Africa
Bean root rot diseases caused by soil-borne pathogens like Pythium and Fusarium species are an increasing problem in East and Central Africa, causing substantial yield losses. The document summarizes efforts to characterize the pathogens, identify resistant varieties, improve resistance through breeding, and develop integrated management strategies. Key results include identifying 11 pathogenic Pythium species in the region, sources of resistance in varieties like RWR 719 and MLB-49-89A, and developing molecular markers for use in marker-assisted selection.
Selectable Markers to Marker‑Free Selection in Rice
Inadequate rice production worldwide is largely attributed to abiotic and biotic stresses, along with high sensitivity of
cultivable plant germplasm. In the field of cereal biotechnology, rice engineering plays an important role in achieving tol
erance to such stresses. Plant transformation and selection play crucial role in rice engineering. This review summarized
the antibiotic, herbicide and metabolic selection marker genes (SMG) employed in diverse rice engineering studies. These
SMGs are no longer required after the transformation has been achieved, hence undesirable at the commercial level. This
study also included several strategies employed in rice engineering to eliminate such foreign DNA elements. These include
co-transformation, site-specific recombination, transposon and CRISPR base approaches. CRISPR/Cas9 being simple and
efficient, is considered a crucial step toward clean gene technology. Further ease and applicability of CRISPR/Cas9 in the
embryos directly can help us to modify target genes with efficient marker-free selection in minimum time. Overall, this review
summarizes and analyse the recent advances that have enormous potential in rice improvement.
Ymv tolerance in greengram
1. The document discusses mungbean yellow mosaic virus (MYMV) which is a major biotic stress for mungbean crops. MYMV is transmitted by the whitefly vector Bemisia tabaci and causes significant yield losses.
2. Research has found that resistance to MYMV in mungbean is controlled by a single recessive gene. Studies identified RAPD markers linked to the MYMV resistance gene which can enable marker-assisted selection for resistant varieties.
3. Breeding efforts aim to develop MYMV-tolerant mungbean varieties through identification of resistant lines, interspecific crosses, and induced mutations. The ultimate goal is generating superior genotypes with durable resistance to minimize yield losses
Breeding for Development of Climate Resilient Chickpea.pptx
The breeding for the development of Climate Resilient Chickpea is a critical initiative aimed at enhancing the productivity and adaptability of chickpea genotypes under challenging environmental conditions. Chickpea, a vital pulse crop globally, faces yield limitations due to the combined impact of heat, cold, drought, and salinity stresses. The average yields, currently far below the potential, necessitate the development of highly productive and resilient chickpea cultivars. Traditional breeding methods and modern genomic resources, including molecular markers, genetic maps, and QTL identification, have been instrumental in enhancing grain yields and stress adaptation. Marker-assisted backcrossing has successfully produced cultivars like Pusa Manav, demonstrating the effectiveness of genomic technologies. Additionally, the adoption of gene-editing technologies, such as CRISPR-Cas9, holds promise in accelerating genetic gain for stress-related traits.
Diversity of plant parasitic nematodes associated with common beans (Phaseolu...
Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to 60% on beans. Though bean production is important in the Central highlands of Kenya, information on PPN associated with the beans in the region is lacking. This study was therefore undertaken to establish the diversity of PPN associated with common beans and to assess the root knot nematode damage on beans in the region. The study covered 50 farms (32 in Kirinyaga and 18 in Embu Counties) distributed in eight localities namely Kibirigwi (L1), Makutano (L2), Kagio (L3), Mwea (L4) and Kutus (L5) in Kirinyaga County and Nembure (L6), Manyatta (L7) and Runyenjes (L8) in Embu County and covering three Agro Ecological Zones (AEZs); UM2 (L1, L2, L3 & L4), UM3 (L5, L7 & L8) and UM4 (L6) AEZs. Manyatta (L7) and Nembure (L6), had the highest and second highest gall indices, respectively, while Kibirigwi (L1), Makutano (L2) and Mwea (L4) had some of the lowest gall indices. The most common PPN in bean roots were Meloidogyne spp. Pratylenchus spp. and Scutellonema spp. with a frequency of 94.38%, 78.25% and 59.13%, respectively. This further confirm the importance of these nematodes in bean production systems. Upper Midland 3 (UM3) AEZs and UM4 had higher nematode population densities and diversity than UM2. Disease severity and nematode composition and distribution were notably low in the irrigated areas Kibirigwi, Kagio and Mwea compared to rain-fed areas such as Makutano, Nembure and Manyatta.

Assessment of Uganda?s Farmers? Perception and Knowledge on Maize Cob Rots to...Journal of Agriculture and Crops
Stenocarpella maydis and Fusarium graminearum maize cob rots are two most devastating cob rots in maize which causes yield losses and reduce grain quality as a result of mycotoxins which is produced from this fungus. Developing varieties resistant to cob rots is a practical and economic strategy that provides cheaper protection against yield loss and poor grain quality. There is still low adoption of improved varieties partly because of limited incorporation of farmer preferred standards. Therefore farmers’ preferences and perceptions should be captured early in a breeding program to enhance the adoption of released varieties. A focus group discussion (FGD) participatory approach was used in four districts of Uganda to assess farmers’ perceptions on maize cob rots and to investigate the possibilities of breeding for farmer-preferred cob rot resistant varieties. Semi- structured questionnaires were administered to selected seed merchants to consolidate and verify farmers’ reporting on seed varieties. Results ofinvestigationsuggested that absolute cob rot resistance was associated with undesirable traits such as small seededness, late maturing and low yields. Yield and earliness were the most preferred farmer agronomic traits, with a farmer-preference mean derived score of 4.5 and 3.75 respectively from the total of 5. In this regard, selection for farmer-preferred cob rot resistance varieties should strike a balance between yield and or earliness with cob rot resistance.Ojwang et al 2016_Food Security

A varietal diallel of eight parents (3 sweet corn, 1 popcorn and 4 field corn) was evaluated at the Teaching and Research Farms of College of Agriculture, Lafia and Federal University of Agriculture, Makurdi respectively, to estimate combining ability, heterosis and gene action. The experiments were laid out as 8x8 α-lattice design with three replications in both locations during the 2018 rain-fed cropping season. Data was collected on emergence count, chlorophyll content, days to tasselling, days to silking, plant height, ear height and grain yield. A significant difference (p≤ 0.05 and p≤ 0.01) in the General Combining Ability (GCA), Specific Combining Ability (SCA) and Reciprocals was observed, with apparent additivity for all the traits. Both negative and positive GCA, SCA and Reciprocal effects and heterosis were observed for all the traits studied. Recurrent selection in TZY-sh2-Y, MAW-sh2-W, SAMMAZ 39, TZEE 2009 and MAY-PC-Y for earliness, dwarfism, vigour and yield was recommended for further breeding towards the improvement of these genotypes in the Southern Guinea Savanna ecology of Nigeria.

Srep18078
This study investigated the impact of expressing banana Xanthomonas wilt resistance genes (hrap and pflp) in transgenic banana plants on non-target bacteria. The researchers found no statistically significant differences in the bacterial communities associated with transgenic banana plants versus non-transgenic controls when grown under field conditions for three years. Both the rhizosphere soil and pseudostem endosphere were dominated by gammaproteobacteria, especially Xanthomonadales in the rhizosphere and Pseudomonadales and Enterobacteriales in the pseudostem. However, the expression of resistance genes did not result in changes to gammaproteobacterial diversity. Thus, the transgenic expression appears to have no consequences for non-target

This document summarizes a study on genetic variability, heritability, and traits related to late leaf spot tolerance and productivity in a recombinant inbred line population of groundnut. The study evaluated 106 recombinant inbred lines plus parental lines. High genetic variation was observed for traits related to late leaf spot score, yield, and other components. High heritability and genetic advance were found for traits like late leaf spot score, 100-seed weight, and haulm weight per plant, indicating these are controlled by additive genes and good for selection. Several lines were identified with improved late leaf spot tolerance, early maturity, yield, and other traits.
PIGEON PEA BREEDING- MASTER SEMINAR
The document summarizes a seminar on pigeon pea breeding, including its achievements, challenges, and future strategies. It discusses pigeon pea's importance as a nutritional crop and describes traditional breeding approaches that have focused on developing varieties with resistance to biotic and abiotic stresses. Recent developments include identifying genetic markers for disease resistance and developing the first hybrid varieties using genetic male sterility systems, though these hybrids did not widely reach farmers due to high production costs. Moving forward, the document recommends continuing to expand genetic diversity and identify new sources of stress resistance from wild relatives to develop higher yielding pigeon pea varieties.
