to study combining ability and genetic parameters of seed yield trait in rapeseed, eight lines of rapeseed were evaluated by a design of half diallel cross. seeds of f1 generation and their parents were grown in a 6 × 6 simple lattice design with two replications. according to the analysis of variance, general combining ability (gca), specific combining ability (sca) and mean squares of genotyp...

the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...

combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. parents and hybrids differed significantly for general combining ability (gca) and specific combining ability (sca) effects, respectively. the variance due to gca and sca showed that gene action was predominantly additive...

combining ability, gene action, heritability and other genetic parameters in bread wheat under drought stress condition were evaluated using half diallel design. nine wheat cultivars and 36 derived f1 assessed in a randomized complete block design with three replications in shahid bahonar university of kerman research field in 2013. evaluated genotypes showed high diversity for all traits. gene...

in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...
