Box-plots showing distributions of EFB, SP, BY, and TSW within types I, II, and III. (A) (B) (C) (D) are phenotypic details for EFB, SP, BY, and TSW, respectively. 08WH, year 2008 Wuhan; 09WH, year 2009 Wuhan; 09YC, year 2009 Yichang; 09HG, year 2009 Huanggang. aa represents genotype pBnA7.SUT1.a- BnA7.SUT1.a; ba represents genotype pBnA7.SUT1.b- BnA7.SUT1.a; and bb represents genotype pBnA7.SUT1.b- BnA7.SUT1.b. * t-test between ba genotype and aa genotype, between bb genotype and aa genotype significant at P = 0.05, ** significant at P = 0.01; ※ t-test between bb genotype and ba genotype significant at P = 0.05, ※ ※ significant at P = 0.01.
