摘  要:
应用程侃声先生提出的形态指数法,对创新水稻种质宜恢1577从稃毛、酚反应、第1~2穗节间的长度、抽穗时壳色、叶毛和粒形这6个性状进行鉴别,确定宜恢1577是偏粳型水稻材料;用4个不育系与6个恢复系组成4×6不完全双列杂交作配合力分析,结果宜恢1577一般配合力效应值为0.226,明恢63为-0.113,认为宜恢1577一般配合力优于明恢63。

摘  要:
This paper made an identification about six agronomic trait of Yihui 1577 including lemma hair, phenor reaction, the first and second internode's length, the hull color while heading, leaf hair and grain shape with the morphological index method founded by Prof. Chen Kansheng. This study has proved Yihui 1577 belonging to japonicalinous restorer line. Yield combination analysis of Yihui 1577 was made by partial complete double cross design with 4 CMS lines and 6 restore lines. The result showed that the general combination ability effect value of Yihui 1577 and Minghui 63 was 0.226 and -0.113, indicating Yihui 1577's general combination ability was prior to Minghui 63's.
