摘要
鉴定了来自江西省农科院等单位提供的131份水稻品种(系)材料对稻瘟病的抗性,其中抗病的7份,中抗的22份,中感的28份,感病的58份,高感的14份。感病材料占77.52%,抗病类型的材料仅占22.48%。加强育种中间材料的抗病性鉴定有利于提高抗病育种之成效。
131 rice breeds provided by Jiangxi Academy of Agricultural Sciences and so on had been evaluated for their resistance to rice blast, in which 7 were resistant, 22 were moderately - resistant, 28 were moderately - susceptible, 58 were susceptible, 14 were highly - susceptible. The susceptible breeds accounted for 77.52%, and the resistant did only 22.48%. The effective method of improving disease -resistant rice breeds was to enhance the resistance identification for medial breeding materials.
