Interpretive Summary:

Technical Abstract: Hybrid rice breeding in the US has depended largely upon male-sterile lines originating in China or from other Asian sources. By contrast, the program in Arkansas has developed all of its male-sterile lines at Stuttgart,AR using germplasm accessions available in the USDA Rice Germplasm Collection stored at Aberdeen, ID. Crosses between genetically diverse accessions have resulted in 18 two-line (EMS) and 6 three-line (CMS) male-sterile lines that are being developed and used for testing hybrid combinations. The accessions were obtained from Indonesia, West Africa, Madagascar, Japan, Sri Lanka, and the United States. Several male-sterile lines cross well with locally bred restorers.
