摘    要:采用相关,回归,通径分析等方法研究了不同群体水稻产量及产量构成因素的相互关系。结果表明,不同群体水稻产量构成因素表现不同,单位面积穗数随着群体变小,穗粒数随着群体变小而增加,但有一定限度,千粒重随群体变小而增加,通径分析表明;穗粒数对产量的贡献最大,单位面积穗数次之,千粒重再次之,空秕率最小。

关 键 词:群体 水稻 产量 产量性状 通径分析

Abstract:With the methods of correlation and regression balance and path coefficient analysis, relationship between rice yield and its components were studied in different rice populations.The results show that rice yield components are significant in different rice populations. With rice density decreasing, panicle number decreases, grain number per panicle increases limitedly, and so does! 1 000-grain weight. Path coefficient analysis shows that in contribution to rice yield, grain number per panicle comes first, the panicle number second, 1 000-grain weight third and blighted grain rate last.
Keywords:rice  yield  yield component  path coefficient analysis
