Root cause of good and bad - AgriYouthNepal Friday Sharing with Dipendra Shahiagriyouthnepal
The world is so much divided on the GMO debate. The world population is expected to reach 9 billion by 2050, and billions of people go to bed hungry each day. To tackle the problem of poverty, hunger and malnutrition, scientists have developed plant varieties that could fight disease, enhance flavor, resist pests, improve nutrition and survive drought by modifying the DNA of one organism through the introduction of genes from another. Around the world, communities are fighting against the cultivation of genetically engineered crops while there are scientists who advocate for GMOs. Are they safe? How do they impact the environment? Can they improve food security? Is the world better off with or without GM food?

Introduction to genetic engineering technologies and principles at B4FA 2013 Accra media fellowship workshop
For more information please see www.b4fa.org
The advances of modern plant technologies, especially genetically modified crops, are considered to be a substantial benefit to agriculture and society. However, so-called transgene escape remains and is of environmental and regulatory concern. Genetic use restriction technologies (GURTs), developed to secure return on investments through protection of plant varieties, are among the most controversial and opposed genetic engineering biotechnologies as they are perceived as a tool to force farmers to depend on multinational corporations’ seed monopolies. In this work, the currently proposed strategies are described and compared with some of the principal techniques implemented for preventing transgene flow and/or seed saving, with a simultaneous analysis of the future perspectives of GURTs taking into account potential benefits, possible impacts on farmers and local plant genetic resources (PGR), hypothetical negative environmental issues and ethical concerns related to intellectual property that have led to the ban of this technology

All living organisms have the ability
to improve themselves through
natural means in order to adapt to
changing environmental conditions.
However, it takes hundreds of years
before any detectable improvement
is obtained. Man then learned how
to domesticate and breed plants
in order to develop crops to his
own liking and needs using various
means including biotechnology.
Biotechnology is defined as
a set of tools that uses living
organisms (or parts of organisms)
to make or modify a product,
improve plants, trees or animals,
or develop microorganisms
for specific uses. Agricultural
biotechnology is the term used in
crop and livestock improvement
through biotechnology tools. This
monograph will focus only on
agricultural crop biotechnology.
Biotechnology encompasses a
number of tools and elements of
conventional breeding techniques,
bioinformatics, microbiology,
molecular genetics, biochemistry,
plant physiology, and molecular
biology.
The biotechnology tools that
are important for agricultural
biotechnology include:
- Conventional plant breeding
- Tissue culture and
micropropagation
- Molecular breeding or marker
assisted selection
- Genetic engineering and GM
crops
- Molecular Diagnostic Tools

7. ORGANIC AGRICULTURE (IFOAM)
“Organic Agriculture is a production system that sustains the health
of soils, ecosystems and people. It relies on ecological processes,
biodiversity and cycles adapted to local conditions, rather than the
use of inputs with adverse effects.”

In financial year 2020, over two percent of the net area in India was under organic farming, a major
increase
from last year (4.3 million Ha). In general, the area under organic farming has increased continuously,
signifying more demand for organic food.
11. ORGANIC PRODUCERS
organic producers worldwide : 3.1 million
India with the highest number of producers (13,66,000),
Uganda (2,10,000),
Ethiopia (2,04,000).
A total of 72.3 million hectares were organic at the end of 2019, representing a growth of 1.6 percent or 1.1
million hectares compared to 2018.
Australia has the largest organic agricultural area (35.7 million hectares),

12. DEFINITION OF ORGANIC PLANT BREEDING
ACCORDING TO IFOAM NORMS 2012
12
General Principles :
Organic plant breeding is
sustainable, enhances
genetic diversity.
Organic breeding is always
creative, cooperative and
open for science, intuition,
and new findings.
Organic plant breeding is a
holistic approach.
Organic plant breeding is
based on viable plants.
Organic varieties are
obtained by an organic
plant breeding program.
13. REQUIREMENTS:
Plant breeders shall select their
varieties under organic conditions
that comply with the requirements of
this standard. All multiplication
practices except meristem culture all
shall be under certified organic
management
Organic plant breeders should not use
genetic engineering……..!
Organic plant breeders shall disclose
the applied breeding techniques.
Organic farming looks at the
breeding of new varieties in a
holistic way.

14. The genome is respected
as an impartible entity .
The cell is respected as an
impartible entity .
Technical interventions not
allowed
The natural reproductive
ability of a plant variety
respected. NO terminator
technologies
Organic plant breeders
may obtain plant variety
protection, but organic

16. AT PRESENT PLANT BREEDING SCENARIO :
16
FiBL., 2015
Over the past several decades, plant breeding has become increasingly formalized and centralized.
Most breeders working for large seed companies, as well as most public breeders, focus their attention
primarily on the largest markets for seed
The three largest companies Monsanto, DuPont and Syngenta control 53 % of the global proprietary seed
market.
This focus on the needs of large-scale, conventional agriculture leaves organic farmers without varieties that
are adapted to then needs of their systems.
19. BREEDING OBJECTIVES FOR DEVELOPING VARIETIES SUITED TO
ORGANIC CONDITIONS :
19
Optimal adaptation to local climate and nutrient dynamics.
Nutrient efficiency
Tolerance to mechanical weed control
Durable resistance and tolerance against pests and diseases
Improving legume symbiotic effectiveness
Rhizosphere competence for disease suppression
Yield stability
Storability
Human nutritional, sensorical quality and some secondary metabolites may be valuable in resistance to human diseases.
Organic plant breeding aims should be defined on a crop by crop bases involving farmers, breeders, traders, and consumers
20. BREEDING TECHNIQUES :
In breeding , various techniques can be applied to different anatomical levels of a plant :
Whole plant level, i.e. the single plant, its progeny or a population
Tissue level, i.e. the plant parts, organs or cell cultures
Cell level, i.e. an isolated single cell, protoplasts, pollen or egg cell
DNA level, i.e. the nuclear DNA or extra-chromosomal DNA
20
21. DIFFERENT BREEDING TECHNIQUES FOR OPB :
Inter-specific hybrids:
Critical issues from the perspective of organic farming:
Crossing barriers between species are not clearly defined boundaries, but become stronger with
increasing differentiation of the species, i.e. the chance of successful fertilization and seed
formation decreases correspondingly.
Technical interventions, such as in vitro fertilization of the egg cell and pollen or in vitro
cultivation of the embryo shortly after fertilization not
allowed except……
21
22. EMBRYO RESCUE IN PLANTS :
In order to improve frequency of progeny of wide crosses, the embryo is transferred to artificial media in rare
cases. The embryo is derived from natural fusion of egg and pollen cell.
22
23. BRIDGE CROSSING :
Critical issues from the perspective of organic farming:
None
23
24. CGMS :
Critical issues from the perspective of organic
farming:
seed saving is not possible. These individuals may only be used
as mother plants for further breeding. Male sterility is
passed on to the progeny.
24
25. SHUTTLE BREEDING :
Critical issues from the perspective of organic farming: None
25
26. PROTEOMICS / METABOLOMICS :
Critical issues from the perspective of organic farming:
none unless chemical or genetically engineered plants are not
Involved in cultivar development
26
27. CLONAL VARIETIES :
Critical issues from the perspective of organic farming:
Application of synthetic rooting hormones and pesticides
are prohibited
27
28. APOMIXIS :
Critical issues from the perspective of organic farming:
None unless it is not induced through chemicals
28
29. SYNTHETIC VARIETIES :
Critical issues from the perspective of organic farming:
None and in open pollination care should be taken to
Prevent out crossing with conventional grown varieties and GMO
29
30. POLYPLOIDISATION :
Yes, if natural colchicine and if applied on intact seed or plants
Tetraploid plants occur in nature but can also be induced by anti-mitotic drugs, e. g. colchicine or oryzalin.
Tetraploid plant often show higher vigor. The antimitotic drug can be obtained from plants. Application can
take place on the whole seed or on seedlings. No in vitro step is necessary.
30
31. MARKER-ASSISTED SELECTION:
Critical issues from the perspective of organic farming:
Plants are evaluated merely based on their DNA Sequence,
So none
1. Early generation marker-assisted selection
2. Marker-assisted Backcrossing
31
32. MARKER ASSISTED GENE PYRAMIDING (MAGP) :
Pyramiding is a breeding strategy for taking genes from different parents and stacking them in one progeny
MAGP is one of the effective method for accumulating multiple resistance genes, it is one of the most
important applications of molecular markers to organic plant breeding.
It is used for traits which are quantitative in nature oa
Steps Cumulating of all target genes in a single genotype
32
Homozygous state
Pedigree
37. SPEED BREEDING :
The principle behind speed breeding is to use optimum light intensity, temperature, and daytime length
control (Croser et al.)
Speed breeding had been reported to shorten generation time by extending photoperiods ,while certain crop
species, such as radish (Raphanus sativus), pepper (Capsicum annum), and leafy vegetables such as Amaranth
(Amaranthus spp.) and sunflower (Helianthus annuus) responded positively to increased day length
It is not allowed by using phytohormones
37
39. FAST TRACK BREEDING BY SINGLE SEED DESCENT
In order to speed up the breeding process, plants are
stressed by reduced space, or water to cause fast onset
seeds allowing several generations per year, e.g. wheat, ground
nut.
39
Sejal ., et al 2019
40. DOUBLE HAPLOIDS OBTAINED BY POLLINATION WITH INDUCTOR
LINE AND SPONTANEOUS DUPLICATION (IN VIVO) SHGD :
Egg cells can be induced by cross pollination with inductor line into develop haploid embryos without fusion of
the egg cell and pollen and, thus, no recombination of genes. The haploid embryo can spontaneously double
their chromosomes to become homozygous double haploid plants . This was a standard practice in maize
breeding.
All steps are in vivo;
no in vitro culture,
no application of chemicals.

IFOAM., 2017
41. ECO-TILLING = TARGETING INDUCED LOCAL LESIONS IN GENOMES
AND DECO-TILLING :
Analysis of natural available genetic diversity by reverse genetics
A system to detect SNPs that we call DEco-TILLING. The DEco-TILLING method facilitates the development
of useful genotyping assays rapidly and inexpensively and can reduce bias.
41
42. TRANSPOSONS :
Transposons are jumping genes that occur in nature and are responsible for mutations. Transposon activity
can be modified in order to increase mutation rate. This can be done by chemicals or by physical stress like
drought or heat.
42
47. OBJECTIVES :
To develop a tomato MAGIC population;
To perform an organic PPB program, in order to obtain new varieties adapted to organic condition.
To evaluate the selected seedling by the Marker Assisted Selection (MAS), for the pyramiding of interesting
genes that are present in the eight founders;
To obtain the RILs through SSD that will be genotyped to find QTLs and develop new molecular markers for
important agronomic traits.
47
48. MATERIALS AND METHODS :
The Solanum lycopersicum lines were selected for the resistance to fungi, bacteria and viruses The Solanum
cheesmaniae is a wild relative accession and it was selected for traits as biotic and abiotic stress tolerance,
yield and resiliency.
48
50. PARTICIPATORY PLANT BREEDING APPROACH :
The 400 G4 tomato plants obtained in summer 2017 was used in participatory breeding programs (PBB).
This activity was carried out during the spring–summer 2018 growing season on three Italian organic farms:
North ,Central and South Italy.
The farmers, in collaboration with the scientists, selected the most desirable plants of the core collection in
their own fields.
The field experiments carried out in three farms were conducted by applying the local technique for tomato
organic production.
50
51. FARMERS EVALUATION :
single plant evaluation was visually performed by farmers, researchers and technicians, who individually
indicated a score ranging from 1 (= bad value) to 4 (= very good value).
On the basis of this score, the fruits were collected from the selected plants and were evaluated for the
quality parameters.
51
52. Finally, the fruits of these plants were collected, and the selection by the researchers testing other measuring
parameters followed in the laboratory. The total number of parameters evaluated during the selection were :
52
53. Even if the first selection years are not enough to draw a general conclusion on the production of adapted
tomato materials, the findings of this research pointed out that the Participatory Plant Breeding program,
assisted by the molecular analysis, is not only economically and agronomically feasible, but it also
beneficial environmental effects.
this study on organic tomato agronomic sustainability can be considered a key tool to produce plants adapted
to low input crop managements especially in organic production.
53
55. CONCLUSIONS
The MAGIC population developed together with the whole genome sequences of the founder lines and the
collection obtained from the PPB are extremely important to develop genotypes adapted to organic
The production of these materials could represent a stable, long-lasting collection and an important
genetic resource both for scientists and farmers communities.
MAGIC lines were identified new molecular markers associated to important agronomic traits. This research
will further allow us to follow the allelic frequencies evolution in the different environmental conditions.
55
57. OBJECTIVES :
The reintroduction of improved traditional varieties suitable for organic agriculture
The objectives of this work were to evaluate under organic and conventional agriculture several maize
varieties improved for grain yield or quality along with other open-pollinated populations of maize
the past by farmers under traditional agriculture.
57
58. MATERIALS AND METHODS :
They evaluated for agronomic performance and grain quality under organic and conventional agriculture
ten open-pollinated populations, potentially valuable for maize bread or bakery use
Five of these open-pollinated populations (Donostia, Meiro, Rebordanes, Sarreaus, and Tuy)
have been improved for grain yield or flour yield during one or three cycles.
58
60. EXPERIMENTAL DESIGN :
The resulting 20 open-pollinated maize populations and improved cycles from northern Spain and two
commercial checks were evaluated in two farmers fields under organic and conventional agriculture.
Five organic environments and five conventional environments were used between 2010, 2011 and 2012
60
Grown under organic conditions abiding to IFOAM norms
61. The 22 genotypes were evaluated in trials that followed an experimental design of randomized complete
blocks with three replications.
In each plot they measured :
early vigor
plant appearance
days to silking,
ears per plant,
grain yield
flour yield
grain moisture
100 grain weight,
milling test
grain density
61
62. EVALUATION :
62
When they checked the effects of selection for yield, flour yield, and milling test, They found out that most
regression coefficients were not significant, with most of the significant coefficients being negative.
Only Meiro significantly increased yield under organic conditions while it decreased for Sarreaus. Except for
Donostia with a significant decrease of yield in both organic and conventional conditions.
65. CONCLUSION :
GRAIN YIELD was highest for both commercial checks, followed by Meiro(P)C2 and Martikoenea.
EARLIEST VARIETIES, BASED ON FLOWERING AND GRAIN MOISTURE, were Sarreaus and its improved
cycles, Donostia and its improved cycle, and Martikoenea
Maize hybrids yielded 16 % less under organic than under conventional conditions. As a general trend,
open-pollinated varieties performed better in the organic environments for vegetative traits and in the
conventional environments for yield components.
As conclusion, breeding has been efficient for “MEIRO” in organic conditions
65
PH :Serving the wholeness and integrity of living system at various levels (immunity, resilience, regeneration, sustainability )
For breeding : developed ones should be robust, dynamic and resilient able to benefit from interactions with the surrounding biome in which they grow, and to reproduce themselves and to produce high quality, nutritious food.
PE: is about contributing to optimally functioning of a diversity of site-specific ecological production systems
For breeding : decentralized breeding for regional adaptability and enhancing genetic diversity
and adapt organism to the environment instead of the environment to the organism.
PF: is about serving equity, respect, justice and stewardship of the shared world.
It implies the need to develop new socio-economic structures in breeding to ensure free access to genetic resources, no patents of life, and maintenance and accessibility of diversity for future generations.
PC : is about enhancing efficiency and productivity in a precautionary and responsible manner. We argue that there is plenty of unexplored (and forgotten) knowledge for new multifaceted breeding strategies
means that organic breeding refrains from breeding techniques that interfere directly at DNA level, including cell fusion and mutation breeding
spontaneous haploid genome duplication (SHGD) rate of doubling is 10 to 50 %
Reverse genetics : finding function of gene by analysing phenotypic effect by it
Forward genetics : from phenotype to genotype
Eight tomato lines were selected on the basis on their breeding relevance to develop the MAGIC population: seven Solanum lycopersicum lines obtained by the breeding program of ISI Sementi SpA and one wild accession of Solanum cheesmaniae that belongs to the TGRC coded as LA1407
