摘　　要：研究以新配制的48份粳型两系杂交稻组合及越光和盐丰47为试验材料,对粳型两系杂交稻杂交组合的株高、产量及穗部性状进行比较分析。试验结果表明:杂交稻新组合株高的差异较大,变化范围为98~129.0 cm,极差为31 cm。粳型两系杂交稻新组合穗部性状各指标均存在较明显差异,其中变异系数最大是单穗秕粒数,变异系数达74.04%。The experiment was using 48 combinations of Japonica two-line hybrid rice to compare their heights,yields and grain qualities,Yuegusng and Yanfeng-47 to evaluate its grain qualities,providing scientific basia.The test results show that:There are large differences among the new hybridized combinations,ranging from 98 to 129 cm,range 31 cm.There exist significant differences among ear characters of Japonica two-line hybrid rice,coefficient of variation 74.04%.
