Heterosis Study in Sunflower (Helianthus annuus L.) for Yield Attributing Traits through Line x Tester Matting Design
Journal Title: Grassroots Journal of Natural Resources - Year 2019, Vol 2, Issue 04
Abstract
Heterosis is the increase or decrease in vigour of F1 over its mid or better parental value. The development of new high yielding and stable sunflower hybrids based on hybridization requires information on the heterotic effects for agronomically important traits in the F1 generation. This paper estimates the extent of heterosis for various characters and to isolate promising sunflower hybrids. From the experiment it was revealed that the average heterosis of 8.9% for days to 50% flowering, 65.1% for plant height; 80.3% for head diameter;139.8% for seed yield (kg/ha);107.5% for number of filled seed/head; 5.9% for seed filling %; 10.8% for 100 seed weight, 12.1%for 100 seed kernel weight, 6.5% for hull content; 4.7% for volume weight (g/100 cc); 0.1% for oil content (%;) and 140.4% for oil yield (kg/ha) respectively. In all crosses, seed and oil yield (kg/ha) traits and other desirable traits, P-2-7-1A, CMS-10 A, P-89-1A, EC-601958, R-104, EC-601978, R-138-2, R-630 and R-6D-1 were involved more frequently. Among the 36 sunflower hybrids, for seed yield and oil yield (kg/ha), fifteen crosses displayed significant positive sca effects and performance per se, among them the crosses.
