摘要
应用通径分析和逐步回归相结合的统计方法，研究了诱发籼稻品种ＩＲ１５２９－６８－３－２产生的５０个早熟突变系的高产基因型特征。结果表明：在这５０个早熟系群体中，高产基因型的特征首先是大穗，其次是多穗。将这一结果应用于育种实践，成功地选育出扬幅籼２号、扬幅糯４号和中籼９４１７。
The elementary characters of high yielding genotype were investigated for 50 early mature mutation lines induced from a indica rice cultivar IR 1529 68 3 2 by the statistical procedure of path analysis combined with stepwise regression. The results showed that the characteristics of high yielding genotype was higher panicle and kernels per panicle. Three high yielding rice cultivars, Yangfuxian 2, Yangfunuo 4 and Zhongxian 9417 were bred by applying above results in rice breeding.
