The Program has been reduced from 8 senior staff positions and a total of 14 principal staff positions in 1991, to its current level of 3 senior staff. Improved Rice Gene Pools . The objective of this study is to increase rice genetic diversity and enhance gene pools for higher and more stable yields. Improved Germplasm , which involves identification of progenitors for crossing, evaluation of segregating material, and observational yield trials. These populations are subjected to QTL analysis and suitable isogenic lines are produced for variety release.
Anther culture is used to speed up the process.
Determination of the Physiological basis for Yield Enhancement and Adaptation to Acid Soils. Here the new plant types are characterized and screened for iron toxicity. Their traits are characterized from wild rices and nutrient uptake investigated under low pH and high Al conditions. Finally their traits for intercropping with pastures are studied. This project also involves training, workshops, and support to other related projects both within CIAT and at other institutions.
