Interpretive Summary:

Technical Abstract: Rice has been produced in the United States since pre-revolutionary days. Currently around 3 million acres are harvested each year with 84% of the acreage occurring in the southern US. Public breeding efforts, which began in the early 1920’s, have produced about 150 rice varieties for production in the southern US. We have compiled agronomic and grain quality data from multi-state regional trials, and analyzed pedigree data from the southern US rice breeders to explore breeding trends over the last 30 years. In addition, county level weather and varietal production data have been assembled over this same time period. Genotyping by sequencing (GBS) data have been assembled for the 150 varieties to assess genetic relationships not evident by pedigree, population structure, and patterns of introgression. These databases will be used to explore how breeding genepools and agronomic potential have changed over time and how the southern US rice germplasm can be predicted to respond to changing climate scenarios.
