| 摘 要： | 对1996～2000年的335份江苏省水稻新品种（系）进行了抗稻瘟病性的分析，江苏省新品种（系）中常规中籼和杂交籼稻对江苏省稻瘟病菌有很好的抗性，对参试菌株的全抗率分别为76.6％和85.1％，中粳稻和单季晚粳稻对江苏省稻瘟病菌的抗性相对较差，全抗率为18.2％和32.1％。感病的籼稻品种对参试的稻瘟病菌代表菌株中的1个菌株感病频率较高，对2个或2个以上的菌株同时感病的频率很低，而感病的中粳稻和单季晚粳稻品种同时对参试的稻瘟病菌代表菌株3个或3个以上的菌株表现感病频率较高，并表现出感病谱的多样性。从参试的品种对江苏省稻瘟病菌感病分布情况来看，中G1小种对大多数品种保持了比较稳定的侵染率。 |

| Abstract: | The resistance of 335 rice varieties (lines) of Jiangsu Province to rice blast were evaluated in 1996-2000. The results showed the resistance to rice blast was higher in middle-season indica rice and indica hybrid rice, the resistance ratio to all tested races were 76.6% and 85.1% respectively. While the middle-season japonica rice and late-season japonica rice showed low, the resistance ratio to all tested races were 18.2% and 32.1% respectively. Most of middle-season indica rice and indica hybrid rice combinations were infected by only one isolate; While the middle-season japonica rice and late-season japonica rice were mainly infected by three isolates or more. It indicated that the resistance pedigree of the middle-season japonica and late-season japonica rice was narrow, and appearing diversity. The race ZG 1 kept a stable infection ratio to Jiangsu Province rice varieties. |
