Synergistic Activities

1) Collaborative research and training activities with Chinese colleagues on the genetic and physiological basis of phosphorus efficiency in crops has had significant impact. New varieties of soybean (Glycine max) with greater phosphorus acquisition efficiency are being bred and released in collaboration with Dr. Xiaolong Yan at South China Agricultural University.

2) New varieties of common bean (Phaseolus vulgaris) are being bred and released in Africa and Latin America that carry root traits identified and genetically tagged through research on the architectural basis of phosphorus acquisition efficiency, in collaboration with bean breeders at CIAT and in national agricultural research institutes, funded by USAID.

3) An integrated program to develop new bean varieties with superior adaptation to drought and low soil fertility has been initiated in Mozambique with funding from the McKnight Foundation, including breeding, trait physiology, agroecology, socioeconomics, and nutrition.

4) Formation of ideotypes for drought tolerance and nitrogen use efficiency in maize.
