  1. a: In linkage mapping, “P1 type” indicates marker phenotype that is the same as that of Zhongshuang11, “P2 type” indicates marker phenotype that is the same as that of No. 73290, “not P2 type ” indicates marker phenotype that is not No. 73290 type; in association mapping, alleles are arranged in alphabetical order according to amplified fragment size. b: “P1/P2” indicates that Zhongshuang11 and No. 73290 have the same genotype in association population.
  2. c: Rare alleles with an allele frequency of < 0.05 are treated as missing data in the association population.
  3. d: SWm, SWb and SWw are the mean values from all the experiments, and the details of each experimental analysis are shown in Additional file 1: Table S10.
  4. e: Being followed by the same letter indicates no significant difference at the 0.05 probability level based on a Duncan-test.
