End Date: Dec 31, 2014
Experimental lines will be developed by crossing directly with accessions from the USDA Soybean Germplasm Collection or with experimental lines derived from such accessions. These lines will be tested in local and regional tests to identify lines that are equivalent in yield to the best cultivars available. Lines derived from exotic germplasm will also be developed with herbicide tolerance and resistance to important diseases such as soybean cyst nematode, and root knot nematode. Populations will be developed and tested to identify yield QTL with the favorable alleles originating from exotic germplasm and previously identified QTL will be confirmed. Introgress confirmed yield QTL originating from exotic germplasm into improved cultivars. Fine map yield QTL originating from exotic germplasm. Genomic selection procedures will be developed to help select useful parents from the USDA Soybean Germplasm Collection. Improved germplasm will be developed with better adaptation to the early soybean production system of the mid-south. Maturity group II, III and IV lines with high yield, good seed quality and good germination will be developed for this production system. Develop and test new procedures to introgress useful genes for increasing yield from wild soybean. Develop high yielding experimental lines from 35 wild soybean accessions and genotype those lines to determine the wild soybean contribution. Develop core collection for the USDA wild soybean collection. Map yield QTL from wild soybean. Develop and test lines from crosses between soybean and Glycine tomentella. Confirm the yield of lines already developed that exceed the yield of the recurrent soybean parent.
