Combining ability analysis provides useful information for the selection of parents, in breeding program cucumber at Can tho, VietNam, as well related to nature and extent gene activities involved. Cucumberimprovement involves strategies enhance yieldpotential quality cucumber. Targeting improvement new varieties plants, combining abilities genetic parameters 12 traits estimated from full diall...

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.,...

Heterosis and the nature and combining ability was studied in 7 × 7 diallel cross in maize for grain yield and yield contributing characters. The significant estimates of GCA and SCA variances suggested the importance of both additive and non-additive gene actions for the expression studied traits. Preponnderance of additive gene action was noticed for ear diameter and 1000-kernel weight and th...

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...

Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 2003) and at two locations in Khartoum S...

Selecting appropriate donors and acquiring information about the genetic basis of inheritance is essential for breeding programs. In this study, a diallel cross was produced by crossing 15 progenies with five commercial lines wide diversity different rice traits (grain yield, plant height, days to flowering, panicle blast, brown spots, leaf scald, grain discoloration) in an incomplete design. T...

a study of the combining ability and gene effects, that can obtained through diallel cross analysis provides considerable information to breeders for a design of breeding programs. inheritance and genetic control of yield and its components were studied in a full diallel cross for seven iranian cantaloupe cultivars namely: rish-baba, shah-abadi, samsouri, dastjerdi, magasi-neyshabour, till-toro...
