IDENTIFICATION OF PUTATIVE YIELD ENHANCING QTL FROM EXOTIC SOYBEAN GERMPLASM. CELLULAR AND MOLECULAR BIOLOGY OF SOYBEAN BIENNIAL CONFERENCE. 2002. p. 201. Interpretive Summary: Technical Abstract: This study evaluates exotic soybean germplasm as a source of genes for the improvement of seed yields in North American domestic soybean germplasm. A population was developed by crossing lines of domestic and exotic origin. Traits including days to flower, days to maturity, reproductive period, plant height, lodging, seed yield, and seed protein and oil content was evaluated in replicated field trials at multiple locations in 2000 and 2001. A genetic linkage map was constructed using simple a sequence repeat marker that span the 20 linkage groups of the soybean genome. Significant quantitative trait loci (QTL) were detected using single marker-trait analysis and composite interval mapping methods. QTL introgressed from the exotic germplasm with positive effects on yields were identified. These results suggest that there may be useful genes for yields in exotic soybean germplasm. |
