水稻高产育种中,由于产量受环境影响较大,因此早期世代多通过与产量关系密切,遗传力大的性状的选择,来建立高产生态类型,从而达到选择高产品种的目的。为此;对性状相关的认识,对于后代选择是很重要的。同时,这种知识对确定综合高产栽培农艺措施,也有参考价值。通径分析是相关分析的一种发展,它通过成因分析,更能清楚地显示出各种性状对产量的不同影响。本文以水稻区域试验中的优良品种和品系的16个农艺性状和产量的相关及通径分 In the high-yielding rice breeding, because the yield is greatly affected by the environment, the early generation mostly establishes the high-yielding ecotype by selecting the traits closely related with yield and heritability, so as to achieve the purpose of selecting high-yielding varieties. For this reason, understanding of traits is very important for future generations to choose from. At the same time, this kind of knowledge has some reference value to determine the comprehensive agronomic measures for high-yielding cultivation. Path analysis is a development of correlation analysis that shows clearly the different effects of various traits on yield through genetic analysis. In this paper, the rice regional trials of fine varieties and lines of 16 agronomic traits and yield correlation and path
