Description Sunflower inbred lines (RHA) derived from different sources with Rf gene were evaluated during 2018- 2020.Genetic variability, phenotypic and genotypic coefficients of variation, heritability and genetic advance were assessed for seven traits related to seed yield, its attributing traits and oil content in 50 RHA lines of sunflower. The analysis of variance revealed highly significant differences for all the characters among the RHA lines. The magnitude of differences between PCV and GCV was relatively low for all the traits, indicating less environmental influence. The estimates of GCV and PCV were high for seed yield/plant. High heritability in broad sense estimates (>90%) were recorded for all the traits under study indicating, the predominance of additive gene action and selection of RHA lines based on these characters would be more valid and selected RHA lines are likely produce high yielding hybrids. Effective for target plant selection in early generation.
