主 题：Line X tester Heterosis Combining ability Sunflower
摘 要：The present research was conducted in Line X tester analysis for estimating combining ability and heterotic effects,restorers malesterile(CMS) crossed with seven tester lines 3x7 21 F_1 hybrids of sunflower were further used to estimate their general combining ability(GCS),specific combining ability(SCA) and heterosis effects on main traits of sunflower during *** this study,seven lines of sunflower were tested with three testers 7x3 of sunflower to obtain twenty one F_1 genotypes from Line X tester mating *** was concluded from present study that among the lines,0505 Cms-6,Peshawer-93 Cms-11,Peshawar-93 Cms-12 were the best general combiners to play the vital role in flowering,maturity,plant height,head diameter,seed index,grain per head and 100-grain yield per *** RHP-53,RHP-42,RHP-46 were also the best combiners for all the ***,hybrid 54CMS-1 x RHP-42 showed best specific combiners,while Peshawer-93 exhibited good specific combiners for grain yield per plant,the hybrids,plant height,head diameter,seed index,grain per head and grain yield per plant,*** differences among the tested sunflower genotypes with regard to mean values of all the investigated traits were *** analysis of variance of combining abilities and the analysis of genetic variance components confirmed the non-additive component.
