摘要:

为比较24个水稻品种在鄂西南不同地区稻瘟病发病情况,筛选适合鄂西南种植的水稻品种,在2018、2019年分别在鄂西南10个地点(忠路、来凤、巴东、建始、长阳、鹤峰、宣恩、柏杨和咸丰,以武汉黄陂作对照)种植24个水稻品种,调查叶瘟和穗颈瘟发病情况。结果表明,2019年各地点的发病情况明显高于2018年,10个地点中发病最严重是宣恩,而咸丰2年都没有品种发生稻瘟病。在实验的24个品种中‘荣优华占’抗性最好,适合在鄂西南推广种植。

Abstract:

To compare the incidence of rice blast among 24 rice varieties in southwest Hubei and screen suitable varieties, the 24 rice varieties were planted in 10 locations, Zhonglu, Laifeng, Badong, Jianshi, Changyang, Hefeng, Xuan’en, Baiyang and Xianfeng, with Wuhan Huangpi as control, and the incidence of leaf blast and neck blast were investigated between 2018 and 2019. The results showed that the incidence of blast in all the above areas in 2019 was significantly higher than that in 2018. The most severe outbreak was Xuan’en, and no rice blast occurred in Xianfeng for 2 years. Among the 24 varieties tested, ‘Rongyou Huazhan’ has the best resistance and it is suitable for popularizing in southwest Hubei.

Key words: rice, leaf blast, neck blast, southwest Hubei, variety
