摘要
以 95 8 3c和 96 4 1a 2个稻瘟病菌系接种 ,用累积分布曲线法对三磅七十箩、魔王谷和毫乃焕与丽江新团黑谷的杂交F2 、F3 、BC1群体进行了抗病基因的遗传分析。发现毫乃焕对菌系 96 4 1a的抗性由 2对显性基因控制 ,1对基因对另 1对基因有抑制作用 ;魔王谷对稻瘟病菌 96 4 1a的抗性受 1对显性基因控制 ;三磅七十箩对菌系95 8 3C的抗性由 1对隐性基因控制 ,首次发现三磅七十箩对稻瘟病的抗性由
Inoculated with two strains (95 8 3c, 96 4 1a) of rice blast by means of Cumulative Distribution curve method, 2 sets of F 3, BC 1 populations of variety Lijianxingtuanheigu / Mowanggu and Lijianxingtuanheigu / Sanbangqishiluo and 1 set of F 2 population of Lijianxingtuanheigu / Haonaihuan were tested with two Yunnan strains of Magnaporthe grisea in greenhouse. The results showed that the resistance of variety Haonaihuan was controlled by 2 dominant genes, one gene restricted the other. The resistance of Mowanggu was controlled by one dominant gene. And it was first found by authors that the resistance of Sanbangqishiluo was controlled by one recessive gene.
