QTL Identification of Plant Height and Analysis of Genotype to Soybean in Selection Population
A primary backcross introgression soybean population was constructed by using Hongfeng 11 as recurrent parent and Clark as donor parent. After screened by drought stress, the genotype of selective population were obtained with the whole genome SSR markers, and the frequency of donor genes segments had been analyzed. QTLs of plant height was mapped by Chitest analysis. In total, 11 SSR excessive introgression on 8 chromosomes were detected with X2 test. The QTL identification was conducted by one-way ANOVA (for single marker analysis, P ＜0.01 ). Eight QTLs of RPH were found in A1 , C2, E,F, L, Mand O linkage groups. The QTL at Satt305 in C2 linkage group was coincident with excessive introgression of X2 test.The same with Sat_136 in E linkage group, Satt586 and GMRUBP in F linkage group, Satt156 in L linkage group, GMSL514 in M linkage group. So these QTL were the essential loci for drought tolerance, and the foundation in fine mapping, cloning and molecular breeding of favorable genes related with drought tolerance.
