Description |
An investigation was undertaken during rabi 2008-09 at Main Agriculture Research Station, Saidapur farm, University of Agricultural Sciences, Dharwad. The experimental material comprised of four F2 populations produced by selfing leading commercial hybrids viz., Golden summer, Bomby, Atlas and Orobelle. The F2 populations were grown in an unreplicated yield trial under shade house with misting facility and observations were recorded on sixteen different characters. Considerable variation was observed between as well as within the F2 populations as evidenced by the higher mean and wide range of values for most of the characters studied. High PCV and GCV was observed for fruit weight, fruit volume, seeds per fruit, pericarp thickness and yield per plant. High heritability coupled with high GAM was observed in respect of characters fruit weight, fruit shape index, fruit surface area, fruit stalk length and pericarp thickness. Character association studies revealed positive significant association of average fruit weight (0.743) with yield in all the populations studied. Other fruit characters like fruit length (0.505), fruit surface area (0.572) and number of fruits per plant (0.736) also showed positive significant association with fruit yield per plant and also among themselves indicating that one should not neglect these characters while selecting for yield. Studies conducted to know the contribution of each component trait towards fruit yield per plant revealed that fruit weight (0.8443) and fruit surface area (0.635) are the most important characters contributing to yield through high positive direct effect and also indirectly through other component traits. Number of fruits per plant, fruit volume and growth parameters also contributed towards fruit yield in sweet pepper due to positive direct and indirect effect. For all the characters studied two populations viz., Golden summer and Orobelle emerged as potential for improving productivity in sweet pepper, as revealed by higher genetic variability and character association parameters. |
