摘要
通过对51个品种的倒伏指数进行聚类分析,将51个品种分为高抗倒型、普通型和倒伏型;将高抗倒型植株性状与倒伏型进行对比,得出抗倒伏品种的基部节间的抗折断力较大,基部节间的长度较短,这说明即使在株高较高的情况下,提高基部节间的抗折断力,降低基部节间的长度仍能提高抗倒性,这对目前的超高产育种具有一定指导作用。
The 51 varieties were classified into high - resistant, normal and inverted types by clustering analysis of 51 varieties. The conclusion was contained such as : resistance of the base of the anti-inverted euhivars was larger ,and the length of the base internodes was shorter, with comparison of high anti-inverted plant traits and Lodging type . This showed that even in the case of plant height than to improve the fracture resistance of basal internode, and lower basal internode length could still improve the lodging resistance. This had some guiding effect on the current high - yield breeding.
