摘　　要：选用36个吉林省主栽品种。对其产量与各产量性状进行相关分析和通径分析。相关分析结果表明:除混合千粒重、结实率与产量为负相关外,其他产量性状与产量均呈正相关,株高、每穗粒数、每穴穗数、谷草比与产量达到了极显著正相关。通径分析结果表明:每穴穗数、每穗粒数、结实率、谷草比对产量的作用较大。Selecting thirty-six main cultivating varieties in Jilin Province, the correlation analysis and pathway analysis of yield, traits were carried out. The correlative analysis showed that except mixed 1 O00-grain weight, seed-setting rate have negative correlation with yield, others have positive correlation with yield, plant height, grains per ear, ears per panicle, ratio of grain to grass have extremely positive correlation with yield. The path- way analysis showed that ears per panicle, grains per ear, seed-setting rate, ratio of grain-grass have significant effects on yield.
