Combining Ability Analysis of Yield Component Parameters in Winter Rapeseed Genotypes (Brassica napus L.)
Eight winter rapeseed genotypes GA096, Geronimo, Okapi, Orient, Sunday, Zarfam, SW0756, and Modena were used as parents of a complete diallel mating design. A set of 56 diallel F1 hybrids (with reciprocals) including their parents were evaluated in a 8×8 simple lattice design with two replications during 2007/08. Several agronomic traits like Plant height, number of lateral branches per pod, nu...
متن کاملgene action and combining ability of important agronomic traits in rapeseed (brassica napus l.)
inheritance of yield and its contributing characters in rapeseed (brassica napus l.) was studied in a 8×8 diallel cross through griffing and jinks-hayman analyses. both general combining ability (gca) and specific combining ability (sca) were highly significant for seed yield, seed weight and branches per plant, while only gca for seeds per pod and oil content and only sca for pods per plant an...
متن کاملGenetic analysis of grain yield, days to flowering and maturity in oilseed rape (Brassica napus L.) using diallel crosses
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...
متن کاملcombining ability of quantitative and qualitative traits in rapeseed (brassica napus l.) varieties at two nitrogen levels
the combining ability of quantitative and qualititative traits has been studied quite frequently in rapeseed (brassica napus l.), but rarely at different nitrogen levels. twenty-one genotypes, including 6 parents and their 15 f2 diallel progenies, were evaluated at two nitrogen rates, n0 and n150. a combined analysis of variance revealed significant mean squares of general (gca) and specific (s...
متن کاملGenome-Wide Association Study Reveals the Genetic Architecture Underlying Salt Tolerance-Related Traits in Rapeseed (Brassica napus L.)
Soil salinity is a serious threat to agriculture sustainability worldwide. Salt tolerance at the seedling stage is crucial for plant establishment and high yield in saline soils; however, little information is available on rapeseed (Brassica napus L.) salt tolerance. We evaluated salt tolerance in different rapeseed accessions and conducted a genome-wide association study (GWAS) to identify sal...
