Elucidation the association between yield and agronomic traits in popcorn

Abstract

Maize (Zea mays L., 2n =20) is the most diversified and versatile crop among cereal crops. Among the popcorn inbredlines a significant positive correlation was observed between the number of primary branches per tassel and plant height. Days to 50% anthesis exhibited a strong positive correlation with days to 50% silking and days to 75% maturity. Furthermore, ear length and ear diameter were significantly correlated with the number of kernels per row. The number of kernel rows per ear and the number of kernels per row also showed a significant positive correlation with yield per plant at the genotypic level. Additionally, ear length and ear diameter were significantly correlated with the number of kernels per row. At the genotypic level, ear length, the number of kernel rows per ear, and the number of kernels per row all showed a significant positive correlation with yield per plant. This analysis highlights key associations that influence plant performance and yield, providing valuable insights for maize breeding and selection programs.
