| 摘 要： | 水稻倒伏是严重影响水稻产量与品质的一个重要因素。影响水稻倒伏的因素主要有品种差异、栽培条件及水稻植株高度等,而秆壁厚度和茎粗与抗倒伏性密切相关,茎秆中贮藏物质含量的多少及组成成分决定其抗倒性能,此外,钾、硅等元素与水稻茎秆的抗倒伏性也密切相关。文章在阐述水稻倒伏的遗传学研究的同时提出了在育种上应选择倒伏指数低的品种（系）作为亲本,尤其应采用以亲本倒伏指数低×低的组配育种方式,并指出应从改善水稻栽培条件和加强抗倒伏品种培育等方面来增强水稻的抗倒伏性。

| Abstract: | Rice lodging is an important factor which has serious impact on the yield and quality of rice.The main factors which affect rice lodging are varietal differences,cultivation conditions,plant height and others.Thickness of stem wall was found to be closely related to lodging resistance,the content and composition of storage substances in stem plays decisive role in imparting rice lodging resistance.In addition,potassium,silicon and other elements are closely related to lodging resistance.Genetics research on rice lodging resistance has been discussed in the article,and it is pointed out that rice variety（line） with low lodging index should be selected as parents,especially hybrid combinations of two low lodging index coordinate parents and rice lodging resistance should be enhanced from the aspects of improving cultivation condition and strengthening variety breeding for lodging resistance. |
