[目的]为冬小麦高产抗倒栽培及育种策略提供参考依据。[方法]在大田条件下选用3个不同穗型冬小麦品种,分析其茎秆抗倒性能及产量。[结果]结果表明,重穗型品种兰考矮早8茎秆基部节间特征较好,符合抗倒株型的形态指标,但是个体的健壮弥补不了群体的不足,因此产量不高;中间型品种周麦18节间充实度高、机械强度大,因而有一定抗倒能力;多穗型品种豫麦49基部节间特性及其抗倒能力居中,但是群体较大,弥补了个体的不足,因而产量较高。[结论]不同穗型的小麦品种只要群体适宜,都有一定的抗倒伏能力且获得高产。
[Objective] The research aimed to provide reference for the high-yielding and anti-tilting cultivation and breeding strategies of winter wheat. [Method] Three winter wheat cultivars with different spike types were selected under field conditions to analyze their stem lodging resistance and yield. [Result] The results showed that the heavy panicle variety Lankao Aza 8 had better internodes between stems and stems, which accorded with the morphological indexes of resistant plants. However, the individual’s robustness could not make up for the lack of groups, so the yield was not high. The confluence degree of ZM-18 was high and the mechanical strength was high, so it had a certain ability of lodging resistance. The characteristics of multi-spike variety Yumai 49 and its lodging resistance were middle, but the population was larger, which made up for the deficiencies of individuals. Higher yield. [Conclusion] The wheat varieties with different panicle types had certain lodging resistance and high yield as long as the population was suitable.
