本文仅就利用显性雄性不育基因进行小麦轮回选择育种的选择与交配问题提出一些看法。众所周知,不育株只能由不育株经过异交而产生,因此,全部不育株都是 F_1代。在随机交配而又大量存在复等位基因的轮回选择群体内,不育株不可能获得较好的选择效应。人工安排的株行内姊妹交,也远不及可育株自交纯合速度快。此外,所有影响传粉的 In this paper, we only put forward some opinions on the selection and mating of wheat male-loop selection breeding using dominant male sterility genes. It is well-known that sterile plants can only be produced by outcrossing sterile lines, so all sterile lines are F1. It is impossible for sterile plants to obtain good selection effect in the circling selection population randomly copulated with the presence of multiple alleles. Artificial arrangement of sibling sister line, also far less self-fertile plants and self-homozygous fast. In addition, all affect pollination
