摘 要 ：利用单体分析和多亲本常规杂交 ,研究了小麦多子房性状基因遗传传递规律和细胞质效应。结果表明 :小麦多子房性状有显、隐性两种基因类别 ,均位于 6B染色体 ;粘果山羊草和偏凸山羊草细胞质对 F1杂合显性多子房性状具有抑制表达作用。多子房小麦对 K、Ven型不育系有着不同程度的育性恢复能力 ,恢复度变幅为 4.82 %～ 48.67%。

Abstract:The gene loci and cytoplasm effect of three multi ovary wheat (MOW) lines were studied by monosomic chromosome analysis and nucleus substitution in this paper.The results were as follows:the MOW character was conditioned by both dominant and recessive ge
