大豆回交群体耐旱耐盐的选择牵连效应及响应分析
Hitchhiking effect and responses analysis about drought tolerance and salt tolerance of the backcrossing introgression lines in soybean
摘要
Abstract
In this study, the hitchhiking effects in a backcross population with strong selection under salty and drought conditions were analyzed by scanning multiple molecular loci, and 34.38% of the loci were found with segregation distortion in random population. After drought and salt tolerance selection, the segregation distortion ratio increased to 51.56% and 55. 88%. SSR alleles showed a serious distortion and genotype structure in backcross in-trogression lines changed considerably after drought or salt tolerance selection. Three putative drought - tolerance related loci (Satt338,Satt640 and Sa?_108) and five putative salt - tolerance loci (Sat_271,Sattl26,Satt640, Satt5l3 and Sat_108) were obtained with chi - square test (P <0.0001) based on hitchhiking effect calculated by comparison of the introgressive frequency of alleles between random population and selected population.关键词
