  1. The haplotype at the Scmv1 locus was detected by its flanked SSR markers R1-2 and B4; while the haplotype at the Scmv2 locus was identified by its co-segregating marker DJF004. The genotype SS/SS means both of the Scmv1 and Scmv2 loci are the same as Zheng58 or HuangC; RR/RR means both loci are the same as Chang7-2 or X178; RR/SS means Scmv2 and Scmv1are the same as Chang7-2/X178 and Zheng58/HuangC, respectively; while SS/RR means Scmv2 and Scmv1 are the same as Zheng58/HuangC and Chang7-2/X178, respectively.
  2. P-value and χ2 were calculated by SAS 9.1 using two-way ANOVA.
