摘要
采用累积分布曲线法,在温室人工接种稻瘟病菌系,对3个水稻品种进行了抗性基因分析.结果表明:3个品种对所测菌株的抗性是由一对或两对显性基因控制,在两对基因控制的情况中,存在着基因间互补或重叠作用.
Adopting accumulative distribution curve method and inoculating lice blast strains, resiance genes of three vatieties' were analysed. The result showed: the lesistance of three rice varieties' to these shains was controlled by one of two couples of dominant genes. When controlled by two couple of genes, gene interaction or gene overiap existed.
