| 摘 要： | 利用Charleston×东农594重组自交系构建的SSR遗传图谱及混合线性模型方法对2002—2006连续5年的大豆蛋白质含量进行QTL定位，并作加性效应，加性×加性上位互作效应及环境互作效应分析。共检测到10个控制蛋白质含量的QTL，分别位于第B2、C2、D1a、E和N连锁群，其中1个表现为遗传正效应,9个表现为遗传负效应，另检测到15对影响蛋白质含量的加性×加性上位互作效应的QTL，解释该性状总变异的13.75%。环境互作检测中，发现9个QTL与环境存在互作，贡献率达到4.47%。

| Abstract: | Soybean Glycine max (L). Merr.], widely grown in United States, Brazil, Argentina, and China, is one of the plant protein source. Protein content in soybean is a quantitative trait controlled by multiple genes, and Currently, SoyBase (2007) documented at least 76 QTL associated with protein content that have been mapped in many different populations and environments. The objective of the paper was to investigate epistatic effects and QE interaction effects of QTLs for protein content by mixed linear model. QTLs for soybean protein content were detected in a five-year experiment with the recombination inbred lines (RIL) population derived from a cross between Charleston and Dongnong 594. Ten QTLs with additive effects for protein content were mapped in the linkage groups B2, C2, D1a, E and N, one of which was the positive effect contributed by Charleston, the others of which were the negative effects donated by Dongnong 94. Fifteen QTLs pairs with epistatic effects for protein content in the RIL were detected, accounting for 13.57% of the general phenotypic variation. There existed interaction between 9 QTLs and environment, and the general contribution to protein content was 4.47%. |
