  1. a based on fisher exact test between midparent value (MPV) and hybrid (qvalue < 0.05)
  2. b above two parsents; based on fisher exact test (FDR < 0.05) between two parents and hybrid
  3. c below two parsents; based on fisher exact test (FDR < 0.05) between two parents and hybrid
  4. d based on fisher exact test (FDR < 0.05); hybrid value must be significantly different than midparent value and not significantly different from lx9801hlEW2b parent
  5. e based on fisher exact test (FDR < 0.05); hybrid value must be significantly different than midparent value and not significantly different from Zheng58 parent
  6. f based on fisher exact test (FDR < 0.05); hybrid value must be significantly different than midparent value and within the parental range
  7. g based on fisher exact test (FDR < 0.05); hybrid value must be significantly different than midparent value and not significantly different from lx9801 parent
