Genetic analysis of heterosis for yield and yield components in rapeseed (Brassica napus L.) by quantitative trait locus mapping.
The main objective in this research was the genetic analysis of heterosis in rapeseed at the QTL level. A linkage map comprising 235 SSR and 144 AFLP markers covering 2045 cM was constructed in a doubled-haploid population from a cross between the cultivar "Express" and the resynthesized line "R53." In field experiments at four locations in Germany 250 doubled-haploid (DH) lines and their corre...
متن کاملCombining 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 کاملA Dynamic and Complex Network Regulates the Heterosis of Yield-Correlated Traits in Rapeseed (Brassica napus L.)
Although much research has been conducted, the genetic architecture of heterosis remains ambiguous. To unravel the genetic architecture of heterosis, a reconstructed F(2) population was produced by random intercross among 202 lines of a double haploid population in rapeseed (Brassica napus L.). Both populations were planted in three environments and 15 yield-correlated traits were measured, and...
متن کاملCombining Ability Estimates for Yield Some Traits in Tomato (Lycopersicon esculentum L.) by Line×Tester
12 single crosses (F1) achieved by combining four testers and three commercial lines of tomato were evaluated for their response to water deficit stress and the combining ability of yield and some yield components. The layout was split plots according to randomized complete block design with three replications and three irrigation levels (FC, 60%FC and 40%FC). Crossing among lines and test...
متن کاملEstimation of Combining Ability and Gene Action for Agro-Morphological Characters of Rapeseed (Brassica Napus L.) Using Line×Tester Mating Design
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...
