Estimation of genetic variability in F2 population of sunflower (Helianthus annuus L.)

Estimation of genetic variability in F2 population of sunflower (Helianthus annuus L.)

Research on Crops 7(1): 204-205

In sunflower, three F2 generations of cross combination, namely, PI 307942 x GP 270, CO 3 x GP 270 and CO 3 x TNHP 2 were evaluated during December 2001 for six characters (plant height, head diameter, stem girth, 100-seed weight, seed yield per plant and oil content). High estimates of phenotypic and genotypic coefficients of variation were obtained for 100-seed weight in PI 307942 x GP 270.
