Mining Major Alleles of Oil Content Loci in Soybean[Glycine max(L.) Merr]

Increasing oil content in soybean is an important goal for soybean breeding.Using 18 SSR primers,polymorphisms were examined among 241 germplasms and three major loci of oil content were identified in soybean.These include Satt343,Sat_295,and Satt598.Three unique alleles(Satt343_3,Sat_295_6 and Satt598_7)of these loci had positive correlations with oil contents in soybean using Chi-square and T-test analysis.Two candidate genes relevant to oil content were found within the 3 cM region of Satt343 and Sat_295,respectively.These results may be significant for soybean breeding for high oil content.
