利用野生大豆染色体片段代换系定位单株粒重QTL
QTL Mapping for Seed Weight per Plant by using the Wild Soybean Chromosome Segment Substitution Lines
摘要
Abstract
To study the QTL mapping of seed weight per plant,which is beneficial to increase the yield of soybean.In this study,the BC3 F3 population is a chromosome segment substitution lines which constituted by 161 lines,with the wild soybean ZYD00006 as donor parent and the cultivar Suinong 14 as recurrent parent,selfing and backcross continuously for several years.The genetic background of this population relatively consistent,which reducing the interference greatly and improving the accuracy of QTL mapping.The QTL mapping was combined by ANOVA Method and T-test for independent samples.A total of 9 QTLs underlying seed weight per plant were detected which distributed on 7 linkage groups.Three QTLs were detected by both methods,including QSW-J-1,QSW-J-2,QSW-G-1.2 QTL were in accord with known results.Another 7 ones were the new discovery QTL,which should be specific loci in our materias.The fragment length of QSW-J-1 was 7.0 cM,and the additive effects of it is-2.7 g,which could be used as the first choice loci for further study.关键词
