Haplotypes analysis of genes with variations related to HSW. E1 and E2: Harbin in 2015 and 2016; E3 and E4: Gongzhuling in 2015 and 2016; E5 and E6: Shenyang in 2015 and 2016. In each subgraph, the symbols ‘^*’ and ‘^**’ next to gene IDs represent the suggested significance of the t-test at p < 0.05 and p < 0.01, respectively, “^o” represents mild outliers, “*” represents extreme outliers and error bars represent Std. Deviation
