Discussion

This study demonstrates significant differences in grain yield and popping traits among popcorn hybrids, suggesting potential for improvement.

Crosses showed significant differences for all traits except ears per plant, and positive GCA effects were found for V7, V9, and M3.
Ten hybrids exhibited positive SCA for grain yield and popping volume, indicating their potential for commercial use.
Non-additive gene effects predominated in inheritance patterns, with line × tester interactions contributing significantly to hybrid variance.
The study identified key parental lines and hybrids that may enhance popcorn yield and quality across diverse environments.

Olakojo et al. (2025) studied this question.
