Implication

Analysis reveals non-additive gene action affects grain yield in sorghum hybrids, suggesting new combinations for improvement.

Key Points

  • Heterosis for grain yield was significant, with the hybrid 3183 A x CB 119 showing a 84.22% increase over the mid parent.
  • The analysis of combining ability highlighted specific hybrids as promising, particularly 234 A x CB 127 and 151 A x CB 126.
  • Line x tester analysis was employed to evaluate combining ability among 48 F1 hybrids produced from six lines and eight testers.
  • Non-additive gene action played a key role in grain yield traits, indicating complex inheritance patterns in sorghum.
