Progress 04/01/06 to 03/31/11

Outputs
Progress Report Objectives (from AD-416) To evaluate photoperiod sensitive sorghum germplasm for tolerance to both pre- and post-flowering drought. Approach (from AD-416) Plant 500 sorghum germplasm accessions in a drought-prone environment in Mexico. Lines will be evaluated for tolerance to drought as it relates to their ability to set seed in drought conditions. The goal of this project is to evaluate sorghum germplasm accessions for pre- and post-flowering drought tolerance. Due primarily to the departure of the cooperator for a position outside the cooperating institution, no significant progress was made in FY 2011 in identifying new sorghum germplasm sources of drought resistance. During the life of this project, useful information was gained on identification of sorghum germplasm that might be valuable in sorghum breeding efforts to develop new varieties for use by U.S. farmers in areas where water stress is a frequent problem. The project ADODR monitored the cooperator's performance under this agreement by periodic communications, orally or in writing, and by more intensive interactions at major sorghum meetings, which included appropriate discussions of work progress, problems, and priorities. This project expired in FY 2011.

Progress Report Objectives (from AD-416) To evaluate photoperiod sensitive sorghum germplasm for tolerance to both pre- and post-flowering drought. Approach (from AD-416) Plant 500 sorghum germplasm accessions in a drought-prone environment in Mexico. Lines will be evaluated for tolerance to drought as it relates to their ability to set seed in drought conditions. The goal of this project is to evaluate tropical sorghum germplasm accessions for pre- and post-flowering drought tolerance. In FY 2010, no significant progress was made by the project due to the departure of the key researcher responsible for work at the cooperating institution. The project has been amended to identify a new lead researcher at the cooperating institution who will be responsible for conduct of the work during the remainder of the project's life. The ADODR monitors the cooperator's performance under this agreement by periodic communications, orally or in writing, and by more intensive interactions at major sorghum meetings which include appropriate discussions of work priorities, progress, and problems.

Significant Activities that Support Special Target Populations The goal of this project is to evaluate tropical sorghum germplasm accessions for pre- and post-flowering drought tolerance. In FY 2009, appropriate tropical accessions were selected for study and were grown in central Mexico and in Vega, TX, where annual rainfall is severely limited. Precise measurements of important plant growth parameters under these water-limiting conditions were made. The work, as it progresses, will provide the required information to permit plant breeders to incorporate drought-resistant germplasm into their breeding stocks. Ultimately, the work will result in the development of improved sorghum varieties for use by U.S. farmers in regions where water stress is a frequent problem.

Significant Activities that Support Special Target Populations This report serves to document research conducted under a Specific Cooperative Agreement between ARS and Kansas State University. Additional details of research can be found in the report for the parent project 6202-21000-022-00D, Sorghum Genomics and Germplasm Evaluation.
