International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82434
Abstract
During the past 20 years of close collaboration with CIAT in the cassava breeding program in the Philippines, much has been achieved, not only in terms of human capacity building but also in the acquisition of improved cassava germplasm. These materials were used in a multy-year selection scheme, which culminated…

Cassava Breeding I: The value of breeding value
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/76975
Abstract
Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials—UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how the data at SRT could be used to predict the probabilities of genotypes…

https://hdl.handle.net/10568/76298
Abstract
Amazonian Dark Earths (ADEs) are fertile soils for agricultural production as well as important archaeological resources for understanding the pre-Columbian past of the Neotropical lowland rainforest. ADEs are threatened by expanding land exploitation and there is a need to develop efficient approaches to soil mapping and analysis for documenting these…

Historical climate trends, deforestation, and maize and bean yields in Nicaragua
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/53064
Abstract
Nicaragua has already experienced substantial climate change, in part due to a loss of one half of its forest cover in the last half-century. In this study, we assess the extent to which historical climate trends have contributed to stagnating yields for maize (Zea mays) and bean (Phaseolus vulgaris), the two main staple crops in the…

Development of disease-resistant rice by optimized expression of WRKY45
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/53033
Abstract
The rice transcription factor WRKY45 plays a central role in the salicylic acid signalling pathway and mediates chemical‐induced resistance to multiple pathogens, including Magnaporthe oryzae and Xanthomonas oryzae pv. oryzae. Previously, we reported that rice transformants overexpressing WRKY45 driven by the maize ubiquitin promoter were strongly…
