Genetic Variability and Association Analysis for Yield and Its Component Traits in Sunflower (Helianthus annuus L.)

Twenty-nine sunflower genotypes were evaluated for genetic variability and association of various morphological traits with seed yield. The in Randomized Complete Block Design three replications. Eight biometrical viz., days to 50% flowering, maturity, plant height (cm), head diameter volume weight (g/100 mL), 100-seed (g), oil content (%) yield per (g) recorded. phenotypic genotypic variation washigh weight, indicating that selection will be effective improving these characters. Traits high heritability advance highly amenable which was observed flowering height. trait maturity weregoverned by non additive gene action as it showed low advance. Correlation coefficients measure the degree relationship between two or more variables. key had positive significant correlation (0.61), (0.83) (0.73). Path analysis revealed (0.62), (0.34) (0.30) direct effect on Head highest indirect through (0.45)
