Identification of Novel Associations of Candidate Genes with Resistance to Late Blight in Solanum tuberosum Group Phureja
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82858
Abstract
The genetic basis of quantitative disease resistance has been studied in crops for several decades as an alternative to R gene mediated resistance. The most important disease in the potato crop is late blight, caused by the oomycete Phytophthora infestans. Quantitative disease resistance (QDR), as…

Assessing weather-yield relationships in rice at local scale using data mining approaches
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/76628
Abstract
Seasonal and inter-annual climate variability have become important issues for farmers, and climate change has been shown to increase them. Simultaneously farmers and agricultural organizations are increasingly collecting observational data about in situ crop performance. Agriculture thus needs new tools to cope with changing…

AI-powered banana diseases and pest detection
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/103473
Abstract
Banana (Musa spp.) is the most popular marketable fruit crop grown all over the world, and a dominant staple food in many developing countries. Worldwide, banana production is affected by numerous diseases and pests. Novel and rapid methods for the timely detection of pests and diseases will allow to surveil and develop control measures with greater efficiency. As deep…

Patterns of sequence divergence and evolution of the S1 Orthologous regions between Asian and African cultivated rice species
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/43933
Abstract
A strong postzygotic reproductive barrier separates the recently diverged Asian and African cultivated rice species, Oryza sativa and O. glaberrima. Recently a model of genetic incompatibilities between three adjacent loci: S1A, S1 and S1B (called together the S1 regions) interacting…

Reduction in nutritional quality and growing area suitability of common bean under climate change induced drought stress in Africa
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97890
Abstract
Climate change impacts on food security will involve negative impacts on crop yields, and potentially on the nutritional quality of staple crops. Common bean is the most important grain legume staple crop for human diets and nutrition worldwide. We demonstrate by crop modeling that the…

Adaptation of common bean lines to high temperature conditions: genotypic differences in phenological and agronomic performance
Bioversity-CIAT Alliance (Bioversity-CIAT Alliance)
https://hdl.handle.net/10568/107018
Abstract
The common bean is the most important legume for human consumption and is grown in areas under conditions of varied rainfall and temperature that limit its yield. The objective of the present study was to identify genotypic differences in adaptation of 91 bean genotypes to high temperature…

Abstract
Undomesticated wild species, crop wild relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change and the growing human population. Here, we study 56,342 domesticated hexaploid, 18,946 domesticated tetraploid and 3,903 crop wild relatives in a massive-…

Informal “Seed” Systems and the Management of Gene Flow in Traditional Agroecosystems: The Case of Cassava in Cauca, Colombia
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/42478
Abstract
Our ability to manage gene flow within traditional agroecosystems and their repercussions requires understanding the biology of crops, including farming practices' role in crop ecology. That these practices' effects on crop population genetics have not been quantified bespeaks lack of…

Towards a collaborative research: a case study on linking science to farmers’ perceptions and knowledge on Arabica coffee pests and diseases and its management
https://hdl.handle.net/10568/76547
Abstract
The scientific community has recognized the importance of integrating farmer’s perceptions and knowledge (FPK) for the development of sustainable pest and disease management strategies. However, the knowledge gap between indigenous and scientific knowledge still contributes to misidentification of plant health constraints and poor…

Source-Sink Relationships in Crop Plants and Their Influence on Yield Development and Nutritional Quality
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/99101
Abstract
For seed crops, yield is the cumulative result of both source and sink strength for photoassimilates and nutrients over the course of seed development. Source strength for photoassimilates is dictated by both net photosynthetic rate and the rate of photoassimilate remobilisation from source tissues. This review…
