Summary of molecular marker analysis for each of the crosses.

P1: susceptible parent; P2: resistant parent. Parent specific alleles (PSA) are alleles present in only one of the parents. Shared alleles: are alleles present in both parents and in all their progeny. PSA in progeny: is the average number of alleles present in each individual progeny that originated either from parent P1 or P2 (exclusively).P1：感病亲本（susceptible parent）；P2：抗病亲本（resistant parent）。亲本特异性等位基因（Parent specific alleles, PSA）指仅存在于其中一个亲本中的等位基因。共享等位基因（Shared alleles）指同时存在于两个亲本及其所有后代中的等位基因。后代中的亲本特异性等位基因（PSA in progeny）指每个后代个体中仅源自亲本P1或P2的等位基因的平均数量。
