摘要

在三个环境中，对通过品系×试验机交配设计开发的30个杂交组合与亲本一起进行了评估，以分别评估亲本和杂交组合对产量及其贡献性状的gca和sca效应。根据红花（Carthamus tinctorious L.）基因型在三种环境下的一致表现，发现BHIMA、GMU 3876、GMU 3863、GMU 7351、GMU 2757、AKS 08R和AKS CMS 2B是产量和大部分产量贡献性状的良好通用组合。在这三种环境中，具有高sca效应的杂交种AKS CMS 2A x BHIMA、AKS CMS 2Ax GMU 3876和AKS CMS 2ax GMU 3863对单株种子产量和其他性状都有希望。结果表明，这些亲本可以在杂交计划中用于个体性状的遗传改良。然而，具有高sca效应的有前景的杂交种可以在多地点试验后用于杂种优势育种。

Selection of elite parents and crosses for seed yield and its components using combining ability analysis over the three environments in safflower (Carthamus tinctorious L.)

Thirty crosses developed through line × tester mating design were evaluated along with parents in three environments to estimate gca and sca effects of parents and crosses, respectively for yield and its contributing traits. Based on consistent performance over three environments in safflower (Carthamus tinctorious L.) genotypes, BHIMA, GMU 3876, GMU 3863, GMU 7351, GMU 2757, AKS 08R and AKS CMS 2B were found to be good general combiners for yield and most of yield contributing characters. Hybrids, AKS CMS 2A x BHIMA, AKS CMS 2A x GMU 3876 and AKS CMS 2A x GMU 3863 having high sca effects were found promising for seed yield per plant and other traits over the three environments. The results indicated that these parents could be exploited in hybridization programmes for genetic improvement of individual traits. However, the promising hybrids having high sca effects may be used for heterosis breeding after multi-locations testing.
