MM and mm denote the two genotype of molecular marker M; QQ, Qq and qq denote the three genotype of QTL; r represents the recombinant probability between molecular marker M and QTL; μdenote the overall mean value. a and d denote the additive effect and dominant effect, respectively; q and p denote the genotype frequency of QTL QQ and qq in tester, respectively (p+q = 1).

*When the genotype of QTL in tester is QQ,, and its genotype frequency is q.

#

When the genotype of QTL in tester is qq,, and its genotype frequency is p.

§

When the genotype of QTL in tester is a mixture of QQ and qq, the genotype frequency of QQ and qq are q and p, respectively.
