摘  要:
为提高鉴定水稻籼粳属性的准确性,用程氏指数法从稃毛,酚反应,第1.2穗节间长度,抽穗时壳色,叶毛和粒形等6项指标对173分水稻材料的籼粳属性进行分析,各项指标的分数加起来后,0~8分为籼(H),9~13分为偏籼(H’),14~17分为偏粳(K’),18~24分为粳(K),以典型籼稻冈46为对照,将供试材料分为籼、偏籼、粳、偏粳四类。

摘  要:
Authenticate the accuracy of the indica or japonica attribute for the sake of the exaltation,utilize Cheng's index method from glume hair, phenol reaction length of the first to second rachis internode,glume color at hea- ding, leaf hair and grain length/width ratio to study on the indica or japonica attribution of 173 rice material, according the mark of every index is added up, 0-8 scores is indica(H), 9~13 scores is indica-clinous(H'), 14~17 scores is japonica -clnious(K'), 18~24 scores is japonica(K) ,Use classic indica G46 as a comparisom and divide materials to four classification.
