基于AMMI模型的杂交高粱籽粒淀粉含量的配合力分析(英文)

[Objective] Analysis of combining ability of starch content variation in hybrid sorghum with the assistant of AMMI model. [Method] Based on the analyses of GCA using incomplete diallel cross(NCII), the SCA of hybrid sorghum was analyzed by AMMI model. [Result] For the starch content change of F1 hybrid sorghum, the effects of GCA and SCA accounted for 81.06% and 17.97%, respectively. In the present study, CMS lines 45A, 29A and restorer lines Hui 1, 44R were proved to be the excellent parent materials for preparing high starch hybrid sorghum cultivars. [Conclusion] The improvement of starch content in parents should be mainly concerned in breeding high starch content hybrid sorghum.
