This project addresses, through breeding, three major production limiting constraints of the acid soil
complex; phytotoxic levels of aluminum and manganese, and low phosphorous availability. In addition to yield, every breeding project must strive to maintain disease resistance and grain quality as a goal.
Screen and evaluate sorghum and pearl millet, in the laboratory and field, for sources of tolerance to low soil phosphorus (P) content and availability; and aluminum (Al) and manganese (Mn) toxicities. Enhancement of elite U.S. and LDC sorghum germplasm with sources of tolerance to Al and Mn toxicities. Train selected U.S. and LDC personnel.
