| 摘 要： | 运用程氏指数法，从辞毛、酚反应、第1稳节与第2稳节间的长度、抽稳时壳色、叶毛和粒形等6项指标对宜恢3551(YR3551)的籼梗属性进行了分析。结果表明，YR3551总评分为15．6分，属于偏粳型水稻；进而确定了强优势杂交组合冈优3551属于水稻亚种间杂种。

| Abstract: | The indica or japonica attribution of the rice restorer line Yihui 3551 (YR3551) was identified on the basis of the six indexes of the Chen's Index Method, i.e., glume hair, phenol reaction, length of the first to second rachis internode, glume color at heading, leaf hair and grain length/width ratio. The results showed that the total score of YR3551 was 15.6, indicating that YR3551 is grouped into the japonicaclinous type. Therefore, it is proved that the new hybrid Gangyou 3551 (Gang 46A/YR3551) with very strong heterosis, which has been certified and released to farmers' fields in Sichuan Province, belongs to intersubspecific hybrid rice. |
