为探讨杂交早稻为什么高产?各主要经济性状与产量间的关系?以杂交早稻威优64组合为例,估计其主要经济性状的简单相关系数,净相关系数,以及七个主要经济性状对单株重的通径系数,并分析各性状对单株重的效应,试图为育种工作提供参考。材料和方法本试验于1986年早季,在我所测交圃试验田中进行。3月15日播种,4月21日插秧,7月23日收获。供试材料威优64组合作为33个测
In order to explore why the yield of early hybrid rice is high? The main economic traits and yield relationship? Early hybrid rice combination of Youyou 64, for example, estimated the main economic traits of simple correlation coefficient, net correlation coefficient, and seven major economic traits of single plant Heavy path coefficient and analyzed the effect of each trait on plant weight in order to provide reference for breeding work. MATERIALS AND METHODS The experiment was conducted in the early 1986 morning in the Tiaoyu experimental field I tested. Sowed on March 15, planted on April 21, and harvested on July 23. Test material Wei You 64 combinations as 33 test
