Abstract

The present investigation entitled, “Study of Combining ability and Gene action in Sunflower (Helianthus annuus L.)” was undertaken to study the combining ability and gene action in parents and hybrids for seed yield and components traits in sunflower in which six female lines were crossed with four male lines so as to obtained 24 F1s. The crosses and parents with two checks, were evaluated in a randomized block design with two replications during Kharif 2017 at Experimental farm at Oilseeds research station, Latur. Data were recorded on 10 characters viz., days to 50% flowering, days to maturity, plant height (cm), head diameter (cm), seed filling (%), 100-seed weight (g), volume weight (g100/ml), hull content (%), seed yield per plant (g) and oil content (%). Among the female parents CMS 10A was good general combiner for days to 50 % flowering, days to maturity, plant height (cm), seed filling (%) and 100 seed weight (g). CMS 2A is found to be good general combiner for), seed fi
