摘要

应用植物数量性状“主基因+多基因混合遗传模型”方法分析了C224对条纹叶枯病抗性的遗传效应，并考查了C224与7个保持系组配的杂交组合对条纹叶枯病的抗性。结果表明，C224对条纹叶枯病的抗性遗传符合2对加性显性上位性主基因+加性显性多基因的混合遗传模型（E1），两对主基因的加性效应分别为-12.47和-24.75，均呈负向显性，上位性和互作效应明显；主基因的遗传率为92.12%，多基因遗传率为2.74%，抗性遗传存在明显的主基因效应。在C224与7个保持系组配的杂交组合中，有5个组合对条纹叶枯病的抗性达到高抗或中抗水平。

Abstract

Resistance inheritance to rice stripe disease of C224 were analyzed by the mixed major gene plus polygene mixed genetic model of quantitative traits. Meanwhile, the resistances of seven crosses derived from C224 and seven maintainer lines were investigated. The results showed that rice stripe disease resistance of the rice restorer line C224 was controlled by two major genes with additivedominanceepistatic effects plus polygene with additivedominance effects(E1 model). These two major genes showed different additive effects and negative dominance effects. One major gene′s additive effect was about -12.47 and the other was -24.75. There were significant epistatic and interactive effects between the two major genes. The heritability of the two major genes was about 92.12%, while the heritability of polygene was about 2.74%. The resistance to rice stripe disease had a significant major gene effect in the seven crosses. Of the seven crosses five possessed high or medium rice stripe disease resistance.
