大豆;油分;位点;等位基因
摘  要：
应用241份国内外大豆资源和18个SSR引物,卡方检验及t检验鉴定出3个与大豆油分含量正向相关的重要位点,分别为Satt343,Sat_295和Satt598,每一位点各含1个与油分相关的重要等位基因,分别为Satt343_3,Sat_295_6和Satt598_7,这3个等位基因对油分含量呈正效应,并在分别在引物Satt343和Sat_295附近发现已定位的与油分含量相关的基因。

摘  要：
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.
