This project focused on evaluating germplasms for resistance to insect pests and develop anthropod resistant varieties.
1. Obtain and evaluate germplasm for resistance toarthropod pests. Determine which resistance sources or mechanisms are most useful to sorghum improvement. Determine the inheritance of insect resistance. 2. Develop and release high yielding, agronomically improved sorghums resistant to selected insects including the sorghum midge. 3. Identify and define potential sources of more efficient plant nutrient extraction and/or utilization in sorghum. 4. Develop agronomically elite sorghums with improved nutrient use efficiencies; 5. Develop new methods for determining nutrient use efficiencies and study responsible mechanisms when appropriate. 6. Determine the effects of nutrient use efficiency on water use efficiency in sorghum.
