摘　　要：以辽宁省的13个杂交粳稻品种为试材,研究了产量性状与产量的相关性。结果表明:产量性状中,穗粒数是影响产量的主导因素,千粒重是影响产量的重要因素。穗长和二次枝梗数对产量影响大,株高对产量也有一定影响。Thirteen hybrid japonica rice combinations bred in Liaoning Province were used as entries, the correlations between yield and yield components were studied. The results showed that the grains per panicle were the main factor for yield and 1 000-grain weight was an important factor. Panicle length and secondary rachis-branches influenced yield greatly and plant height also affected yield to some extent.
