Overview

Combining ability and heterosis affect grain yield in cytoplasmic male sterile rice hybrids, suggesting non-additive gene action predominates.

Key Points

  • Non-additive gene action significantly impacts yield components and hybrid performance in rice cultivars.
  • Higher sca variance compared to gca variance indicates more influential non-additive effects on grain yield.
  • Certain parental lines demonstrated strong general combining ability for grain yield and components.
  • Specific combinations showed better heterotic effects, enhancing hybrid performance for grain yield significantly.
