QTL Analysis of Seed and Pod Traits in Soybean
2012
The population of 149 recombination inbred lines(RIL)derived from the cross of Charleston×Dongnong 594 were adopted.QTLs of one-seed pod,two-seed pod,three-seed pod and four-seed pod form 2006 to 2008 were analyzed by composite interval mapping(CIM)and multiple intervals mapping(MIM)method.Thirteen QTLs and 24 QTLs were mapped by CIM and MIM method,respectively.QTLs were located on 11 linkage groups,and 1 QTL of one-seed pod was mapped by CIM method in two years.One QTL of two-seed pod and 1 QTL of four-seed pod were mapped by MIM method in two years,and the QTL of four-seed pod in two years could explain 72.5% and 37.6% phenotypic variation,respectively.
