摘　　要：应用程侃声提出的形态指数法，对宜恢1577从稃毛、酚反应、第1-2穗节间的长度、抽穗时壳色、叶毛和粒形六个性状进行了鉴别，确定了宜恢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。The indica-japonica character of a novel rice germplasm Yihui 1577 was identified based on six agronomic traits （lemma hair, pheno reaction, internode length between the first and second nachiees, the hull color at heading, leaf hair and grain shape） with the morphological index method founded by Mr Cheng. The restdts showed that Yihui 1577 belongs to japonicalinous restorer line. The yield combination ability analysis of Yihui 1577 made by not complete dual crossing with 4 CMS lines and 6 restore lines indicated that general combination ability effect value of Yihui 1577 was 0.226 and that of Minghui 63 was - 0.113, the former was superior to the latter.
