摘　　要：对利用N离子束和γ射线诱变获得的粳稻日本晴和籼稻"9311"89份株高突变体的株高性状和产量性状进行了相关分析。结果表明,株高和水稻的产量与其构成因素:穗粒数、结实率、千粒重以及穗长、单株茎秆干重有着一定的相关性。株高与穗长、穗粒数、千粒重、单株茎秆干重、单株生产力呈极显著的正相关,与有效穗数呈极显著的负相关。通过对株高与其他产量结构因素的相关分析,进一步了解了株高的变异对于水稻经济产量因素的影响。The total 89 plant height mutant lines induced from rice cultivars Nipponbare and ＂9311＂ by ion beam implantation and γ-rays irradiation were used for analysis of the correlation between plant height and yield component. The results indicated spike length, ear grains, thousand-grain weight, stem dry weight and yield have significantly positive correlation with the plant height, while the number of productive ear has significant negative correlation with it. The correlation analysis of the plant height and yield component will help to reveal the influence of the plant height and the factors of yield component.
