Overview

Analysis of maize genotypes demonstrates significant heterosis and combining ability for yield traits.

Key Points

  • Substantial genetic variability was observed in maize genotypes with emphasis on kernel yield traits.
  • The inbred line BLD 203 and tester WNC 40108 showed optimal performance for kernel yield.
  • ANOVA revealed significant differences in traits, indicating genetic diversity among the maize lines.
  • Heterotic effects and gene action dominance were significant, with non-additive effects prevalent across traits.
