Abstract:
Soybean is a versatile crop due to its multitude uses as a high protein meal and vegetable oil. Seed protein content is an important quantitative traits. To identify the quantitative traits loci (QTL) related to seed protein content,a cross was made with the high protein content variety Qihuang 26 and the low protein content germplasm Huapidou, and derived a F2 population with 170 plants. Two F2∶3 populations were derived from the F2 population in Jinan and Guanxian respectively. SSR marker data of F2 population and phenotype data of F2∶3 population were analyzed with Mapmaker/EXP V3.0 and QTL Cartographer 2.5. One molecular genetic linkage map with 18 linkage groups (LGs) and covering 1 035.6 cM was mapped and 3 QTLs related to seed protein content were identified on D2,E and K linkage groups, explaining 14%,11% and 2％ phenotypic variance respectively in Jinan, and 1 QTL related to seed protein content was identified on E linkage group in Guanxian, explaining 3% phenotypic variance.
