Heterosis and combining ability estimates for the total number of eggs laid per female in silkworm, Bombyx mori L
Heterosis and combining ability for total number of eggs laid per female silkworm Bombyx mori L were investigated in a six parent diallel crossing programme in four rearing seasons. Magnitude of heterosis varied from seasons to season and was not consistent over characters. Effect of season was important in the expression of genetic variances and other parameters studied. Considerable amount to...
متن کاملEstimation of Genetic Parameters, General and Specific Combining Ability in Iranian Endemic Coriander Populations
In any breeding program, knowledge of the nature of gene action involved in the inheritance of traits is a basic requirement. In this research, diallel crosses progenies of six coriander landrace were evaluated in F1 and F2 generations. The genotypes were evaluated in different irrigation conditions in three separate experiments, in which each experiment was conducted in a randomized complete b...

متن کاملgeneral and specific combining ability and heterosis estimation of some cucumber lines for qualitative traits in partial diallel design
partial diallel design can be used to investigate the general and specific combining ability, and heterosis. combining ability and heterosis were studied in a 6×6 partial diallel cross to see the nature of gene action for fruit quality indices in cucumber (cucumis sativus l.) during 2007 to 2009. analysis of variance revealed highly significant differences among all the f1 hybrid means and thei...
متن کاملgeneral yield and specific combining ability and heterosis of some cucumber lines in partial diallel design
combining ability and heterosis were studied in a 6×6 partial diallel cross during 2007-2009 to see the nature of gene action in cucumber (cucumis sativus l.). analysis of variance revealed high significant differences among all the f1 hybrid means and among their respective six parental values for all the traits examined. the mean squares attributed to general combining ability (gca) and speci...
