| 摘 要： | 倒伏是水稻生产中常见的问题之一,倒伏不仅影响水稻产量,同时也影响水稻品质。从20世纪50年代的矮化育种开始,水稻倒伏问题一直受到研究者的关注。不同的研究者对水稻倒伏有不同的分类方法。文章从力学角度、抗倒能力的评价指标以及遗传角度讨论了水稻倒伏的研究现状;同时指出目前的研究大多只停留在理论水平,还没有形成一个统一、准确的抗倒能力评价指标,通过分子标记辅助选择大规模培育优良抗倒伏品种(系)的期望仍未实现。

| Abstract: | Lodging is one of common problems in rice production,and it has impact on the yield and quality of rice.Since the breeding for dwarfness began from 1950's,researchers have paid attention to the lodging of rice all along,and different researchers have different classifications on the lodging of rice.The present research status of rice lodging was mainly discussed in the paper from the view of mechanics,the appraisal standards of the ability of lodging resistance and the heredity.It pointed out that these researches stayed in theoretical level and the unified and accurate appraisal standard is still not formed.Moreover,the expectation that the lodging resistance of rice varieties(line) would be bred through molecular marker-assisted selection has still not yet realized. |
