MM and mm denote the two different genotype of molecular marker M; Q and q denote two alleles of QTL in BCRIL population, Qi (i = 1∼k) represents the multiple alleles of QTL in tester; r represents the recombinant value between molecular marker M and QTL; μidenotes the overall mean value. a, a 1 and a k denote the additive effect of different allele; gi and gi′ (1∼k) denote the genotypic value of the homozygote and heterozygote of QTL, respectively. , .
*When the genotype of QTL is Q 1 Q 1 in tester.
When the genotype of QTL is Q k Q k in tester.
