摘要: 详细介绍了目前国内油菜株型育种的研究现状,分析了油菜理想株型的主要构成要素及其研究进展。提出在油菜株型育种实践中可以将油菜株型分为花前期、花期、角果形成期3个阶段分别进行研究。花前期叶片颜色较深、叶片直立、干物质产量高的油菜株型可以作为理想株型。开花期的花瓣面积小、有效光合面积大的油菜株型可以作为理想株型。角果期田间通风透光、角果皮和茎皮的面积大、光合作用强的油菜株型可作为理想株型。

Abstract: This article described the research situation about plant type breeding of rape, sum up the main elements and study progress about ideotypes of rape. The plant type breeding of rape concluded before the blossom period, flowering stage, pod formation stage. Before the blossom period, the darker leaves, erect type leaves and higher dry -matter yield maybe the ideotypies of rape. In flowering stage, the ideotypies of rape may include the smaller petal area and larger effective photosynthetic. In the pod formation stage, light ventilation, larger pericarp and stem bark superficial area, stronger photosynthesis maybe the ideotypies of rape.
