在1989年和1990年试验的基础上,利用计算机对27个早稻高产品种和36个晚稻高产品种的193个性状的育种值进行了逐步回归和通径分析,得到的结果通过x~2测验和预测准确率测验,其效果都十分理想.

• It is reported that computers were used in the gradual regression and the path analysis of the breeding value of 193 characters of 27 high-yield early-rice varieties and 36high-yield late-rice varieties on the basis of experiment data in 1989 and 1990 in this article,The results were tested with x~2 tests and accurancy calculate tests and their effects were ideal.
