利用高世代回交群体对大豆小粒性状的基因型分析及QTL定位
Genotype analysis and QTL mapping small seed size soybean with advanced backcross population
摘要
Abstract
A set of advanced backcross population were constructed with Suinong 14 as recurrent parent and wild soybean ZYD00006 as donor parent. After comparing with recurrent parent Suinong 14,43 BC3F2 individuals with small seed size were screened out, and another 43 individuals from BC3F2 were used as control (random population ). Nine QTLs ( quantitative trait loci) on seven linkage groups controlling small seed size were detected with genotype analysis by chi - square on genetic hitchhiking, and these QTLs showed positive effect on small seed size. Advanced backcrossing lines were used for mapping QTL related to small seed size, and could benefit molecular assisted breeding.关键词
