Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...

Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling...

Legumes may also be used to extend the production season in the cooland warm-season grass pastures. Growing complementary plant species is an alternative approach Grazing systems using forage legumes increase animal to enhancing pasture production. Our objective was to estimate combining ability for native, warm-season grasses and legumes grown in production (Fribourg et al., 1979; Jung et al.,...

Combining ability analysis for grain yield and its contributing characters was carried out among ten female lines from diverse cytoplasmic male sterility sources, five elite restorers 50 hybrids through Line x Tester mating design. The magnitude of SCA variances higher than the GCA all characters, which indicated predominance non-additive gene action in inheritance these traits it further suppo...

Background: Garden pea (Pisum sativum L. var. hortense) belongs to family leguminosae is an important legume vegetable grown throughout the world during cool season. It self pollinated pulse crop with chromosome number 2n = 2x 14. Based on genetic diversity its primary centre of origin Mediterranean region. used as fresh and processed frozen in India abroad. good source vegetarian protein (6.8%...

Artemisia annua is an important medicinal crop used for the production of the anti-malarial compound artemisinin. In order to assist in the production of affordable high quality artemisinin we have carried out an A. annua breeding programme aimed at improving artemisinin concentration and biomass. Here we report on a combining ability analysis of a diallel cross to identify robust parental line...

inheritance of several yield-based drought resistance indices was studied by a halfdiallel method using seven winter wheat varieties. the parental lines were such chosen as to represent a broad range of drought stress resistance. the experiment was conducted in a split-plot design at the research farm, faculty of agriculture, zanjan university, iran, in 1998. irrigated vs. rainfed regimes w...
