摘　　要：为提高育种预见性和选择效率,对小麦株型问题进行了探讨。认为理想株型应有良好的透光性、遮光性和抗旱保水性,能适应小麦生长的各个生育阶段。选育株型抽穗前紧凑、灌浆后期松散,叶水平角随灌浆进程逐渐加大的品种,小麦功能叶在整个生育时期均能充分截取和利用阳光,有助于提高小麦产量。The ideal plant type of wheat was discussed in order to improve breeding foreseeability and selection efficiency. The ideal plant type of wheat should have good light transmission, light shading, drought-resistant and water retention property, could adapt to each growth stages of wheat. The function leaves of variety could intercept and utilize sunlight sufficiently and the agronomic characters of the variety include compact plant type at early heading stages, incompact plant type at late grain filling stages and the leaf horizontal angle which enlarges gradually along with the grain filling process. These types could contribute to increase the yield of wheat.
