Brief Project Summary:

The goals of this project are to: 1) Identify germplasm with increased heat tolerance by exploiting genetic variability of MG III and IV genotypes; 2) Develop a better understanding of the mechanisms that protect soybean yield from losses during episodes of high temperature stress; and 3) Initiate incorporation of heat tolerance traits into advanced soybean germplasm and development of mapping populations.

This project has advanced an unprecedented set of recombinant inbred line populations (RIL) for targeted and efficient improvement of soybean tolerance to high temperatures. Further this project has provided us 1) germplasm with increased tolerance (and susceptibility) to heat stress, 2) progeny of crosses between heat tolerant and heat susceptible lines as part of RIL population development, 3) preliminary understanding of physiological mechanisms associated with heat tolerance and heat susceptibility. Additional efforts are necessary to advance the unique RIL populations under development to the point where they can be used for genetic mapping which is expected to lead to the identification of novel molecular markers and possibly genes and biochemical pathways that can be targeted to improve soybean heat tolerance.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
