Discussion

Field experiment evaluated 32 sunflower genotypes for genetic variability and yield traits, indicating significant heritability.

Genetic variability was observed for seed yield and oil content in sunflower genotypes.
Traits like seed yield per plant exhibited high phenotypic (54.4%) and genotypic (56.3%) coefficients of variation.
High heritability coupled with high genetic advance for seed yield suggests effective selection conditions.
Results indicate additive gene action predominates in sunflower yield-related traits, aiding future improvement programs.

Naveen et al. (2025) studied this question.
