Abstract:

The present investigation entitled “Heterosis studies in sunflower (Helianthus annuus L.) was undertaken to estimate the heterosis for seed yield and its components in sunflower. The four CMS lines and eight restorer lines were crossed in line x tester model to produce 32 hybrids during Summer- 2017-18 and these 32 hybrids along with two checks were evaluated for days to 50 percent flowering, day to maturity, plant height (cm), head diameter (cm), seed filling percentage (%), 100 seed weight (g), volume weight (g/100ml), hull content (%), seed yield per plant (g) and oil content (%). The magnitude of heterosis over the check Phule Raviraj and MDSFH-411 for most of the characters in the present study were highly appreciable. Among the hybrid viz. CMS-89 x NSH-312 showed the highest significant heterosis for seed yield and its components over the checks Phule Raviraj and MDSFH-411. From the investigation the following hybrids were found promising i.e. CMS-343 x PSMOO-108, CMS-89-1 x NSH-312, CMS-62 x AKSF-12 and CMS-343 x MRHA-2 which showed high per se performance comprising significant standard heterosis for seed yield along with significant heterosis in desirable direction for most of the yield attributes.
