Abstract
A half diallel cross between five divergent sunflower genotypes was evaluated under two contrast locations of Kafr El-Hamam (fovourable soil as a control) and Tag Al-Ezz (as salt affected soil) Agricultural Research Stations using randomized complete block design with three replications. High significance variation among genotypes and their components was detected for all studied traits at both and combined locations. Selection in early generations would be effective at both locations for improving days to 50 % flowering, days to physiological maturity, plant height, head diameter, No. of green leaves plant–1 and seed oil content, but the remaining studied traits took an opposite trend. The parent L125 behaved as the best combiner at both locations for seed weight plant–1 and one or more of its components. The cross L460×L335 was found to be superior and exhibited highest specific combining ability effects and heterosis at both locations for seed weight plant–1 and one or more of its attributes. Gardner and Eberhart and Jones’s analyses (modified Hayman analysis) gives the same information as Griffing’s analysis method 2. Moreover, Hayman’s analysis may be given more information over the others about genetic component, so recommended using any one of these three methods along with Hayman’s analysis.
