摘　　要：以自然结实率与植株形态为育性指标,对野败细胞质的10个恢复系进行恢复基因的遗传分析,结果表明I:R24I、R26、明恢63、527、先恢207、密阳46、R326、岳恢9113、R402、盐恢559,轮回422、R228、R838均具2对独立遗传的主效显性恢复基因,IR24I、R26、明恢63、527、先恢207、密阳46、岳恢9113、R402、盐恢559,轮回422、R228具有2对等位的恢复基因,R326具有2对不等位的主效恢复基因,R838的具有1对不等位的主效恢复基因;利用恢复系杂交后代强恢株出现的机率,评价了16个恢复系材料,其中先恢207、密阳46、R527、明恢63、轮回422、R228强恢遗传传递力高,是优良的恢复系亲本。The natural seed rate percent and some morphological characteristics were used as indicator of plant fertility to conduct genetic analysis to the restoring genes of 10 restorer lines. The results showed that IR24, IR26, MH63, R527, XH207, Miyang46, R326, Yuehui9113, R402, Yanhui559, LH422, R228 and R838 all have two pairs of independent hereditary major dominant restoring gene; IR24, IR26, MH63, R527, XH207, Miyang46, Yuehui9113, R402, Yanhui559, LH422, and R228 have two pairs of allelie restoring gene; R326 was identified to have two pairs of non-allelic major restoring gene; R838 has one pair of non-allelic major restoring gene. According to the probability of strong restorer lines in the segregating population, the 16 restorer lines were evaluated, the results showed that XH207, Miyang46, R527, Minghui63, LH422 and R228 have strong restoring genetic transmission power, which are the good parents of restorer line.
