"Aflasafe: a case study for aflatoxin reduction in crops" presentation by "Ranajit Bandyopadhyay, International Institute of Tropical Agriculture, Ibadan, Nigeria"
The document discusses how breeding has impacted genetic diversity in maize genomes over time. It examines changes in ancestry across the maize genome and how the genome has responded to selection for increasing hybrid yield. Specifically, it finds that changing ancestry, not selection sweeps, has driven diversity loss across heterotic groups. The diversity of ancestral lines making up modern inbreds has decreased as germplasm pools have become smaller and more homogeneous. Within a single breeding program, genetic drift in small breeding populations also reduced diversity despite selection for yield.
Improving drought tolerance in maize (zea mays)Delince Samuel
The document discusses improving drought tolerance in maize. Drought stress can cause over 20% yield loss in maize by stopping cell division and growth. The tasseling and silking stages are most critical. Varieties have been developed with drought tolerance, avoidance, and escape mechanisms. Breeding programs aim to improve drought tolerant varieties through recurrent selection and identify drought tolerant traits and genes to increase their frequency in maize plants. Marker assisted selection and quantitative trait loci analysis can also help breed maize with improved drought tolerance.
Use of biotechnologies to increase the storability and shelf life of fruit ExternalEvents
The document discusses using biotechnology to increase the storability and shelf life of fruit. It notes that fruit currently has limited storability and shelf life, resulting in losses for growers and less food availability. Biotechnology can help by developing cultivars with better storage and shelf life through techniques like gene editing. Specific genes involved in ethylene production and cell wall degradation impact ripening and shelf life. New breeding techniques have the potential to precisely modify these genes in popular cultivars to extend shelf life while maintaining taste. This could help tropical crops like mango that currently have limited export opportunities due to short shelf life.
Biotechnology can help address increasing global food demand through more efficient food production methods. As populations grow, cereal production will need to increase 50% worldwide and rice production in the Philippines will need to increase 40% to feed everyone. Agricultural resources are limited by issues like deforestation, overgrazing, and land conversion. Biotechnology techniques like genetic engineering can help develop crops that are resistant to pests and diseases, have higher yields, and improved post-harvest qualities. The Philippines is researching biotech applications like papaya with delayed ripening, vitamin A-enriched rice, and disease-resistant banana, coconut, and sweet potato varieties to improve agriculture. Some biotech products are already being commercialized like Bt corn resistant to

This document summarizes the process of hybrid seed production for maize. It discusses selecting appropriate parent lines and maintaining isolation distances between male and female lines. Key steps include planting ratios, detasseling the male plants, roguing undesirable plants, and harvesting when seeds reach proper maturity. Multiple inspections are needed to ensure genetic purity is maintained throughout production. Proper post-harvest handling and storage is also important for high quality hybrid maize seed.
Development of transgenics for the abiotic stress tolerance is the need of the hour as the existing plant types were prone to vagaries of climate change and therefore a new technology for the development of abiotic resistant varieties through genetic manipulation is imperative.

The presenter's expectations for the meeting and GLOSOLAN network are to develop competency in soil/plant/water/fertilizer analysis, have periodic country member meetings, and share experiences.
Standard operating procedures (SOPs) are important to have in writing to ensure quality and consistency. Quality assurance (QA) policies aim to prevent errors and ensure standards, while quality control (QC) checks that standards are being met. This poster exercise divides participants into groups to discuss why SOPs are important, what quality assurance entails, whether an organization has a QA policy and how it is implemented, and how quality control is performed.

- Nepal has been working to systematically classify its soils since 1957, completing surveys of 55 districts by 1983, though some high hill districts remained unsurveyed for a long time.
- In 1998 and 2014, soil maps of Nepal were prepared using the USDA and WRB soil classification systems, respectively. Around 6000 soil profiles were studied from five physiographic regions.
- The data from 158 representative soil profiles were analyzed and converted to fit the HWSD format using formulas from Batjes et al. 2017 to standardize the data into layers from 0-30 cm and 30-100 cm.
- Major soils identified include Calcaric Fluvisols, Eutric Gleysols, Calcaric Ph

Assessment and Planning in Educational technology.pptxKavitha Krishnan
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.

Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Maize is vital for food security
in Sub-Saharan Africa
• Over 300 million people
depend on maize in SSA
• Example: consumption in
Kenya 103 kg/ yr/ person
• Maize yield is low (1.8 t/ha
compared to world average of
4.5 t/ha)
• Major constraints:
• Drought
• Low soil nitrogen
• Diseases
• Lack of access to quality
seed Recorded droughts between 1971 and 2000, and
the number of people affected
4. Water Efficient Maize for Africa (WEMA)
• A public-private partnership to develop and deploy
drought-tolerant and insect-pest protection white
maize varieties to smallholder African farmers royalty-
free.
Expected Outputs
• Under moderate drought, WEMA maize expected to
increase yields by 25% over 2008 hybrids
• 15% conventional
• 10% transgenic
• Translates into additional 2 million MT maize during
drought years to feed about 14 to 21 million people in
the long-term.
