摘　　要：以七山占/秋光重组自交系群体为试材,研究亚种特性的变化及其与维管束性状的关系。结果表明,籼粳交后代亚种特征性状、维管束性状都呈现连续变异,表现数量性状的遗传特点。籼粳交后代程氏指数与大小维管束比,大维管束比的相关达到极显著。依程氏指数法与维管束数目比法对籼粳交后代亚种分类的符合度不高。The RILs population that derived from the cross between ＂qishanzhan＂ （indica） and ＂Qiuguang＂ （japonica） was used to study variation about subspecies characteristics and relationship between subspecies characteristics and vascular bundles. The results showed the subspecies characterlstios and .vascular bundles ~ . characteristics all showed continuous variation and genetic characters of quantitative characteristics. There were significant correlation between cheng＇ s index and ratio of large to small vascular bundles, cheng＇ s index and ratio of large to large vascular bundles. The consistent degree between cheng＇ s index and vascular bundles was low.
