The genetic effect and contribution of epistatic QTL for KSRTs detected in Z1 and Z2.

** P≤0.01.aai and aj represent the main effect of the loci i and j, and aij represents the epistatic effect between loci i and j.bR2i, R2j, R2ij, and R2 represent the genetic contribution via the percentage of the total variation explained by the ai, aj, aij and the total interactions for KSRTs respectively.c, d indicate marker intervals mapped to more than one QTL.The genetic effect and contribution of epistatic QTL for KSRTs detected in Z1 and Z2.
