An Expansion of Joint Segregation Analysis of Quantitative Trait for Using P1, P2 and DH or RIL Populations
利用P1、P2和DH或RIL群体联合分离分析的拓展 An Expansion of Joint Segregation Analysis of Quantitative Trait for Using P1, P2 and DH or RIL Populations

More than three major genes controlling quantitative trait are often obtained in QTL mapping. However, it is very difficult to develop joint segregation analysis with three major genes but for DH or RIL population. Therefore, an expansion of the inheritance model, such as linkage between two major genes, three major genes, three major genes plus polygenes, was developed in this paper. Finally, an example of the inheritance of flowering date of soybean for using P 1, P 2 and RIL populations derived from a cross between Keifeng 1 and Nannong 1138-2 was used to explain the procedures.
