近几年来,江苏里下河地区水稻条纹叶枯病发生危害逐年加重,2004年该病暴发流行,大面积水稻普遍减产减收,发病严重的田块甚至颗粒无收。为研究本地区主要粳稻品种对条纹叶枯病的抗性强弱,筛选出综合性状表现较好(高产、优质、多抗等)的品种,作为大面积水稻生产的当家品种利用,20 In recent years, the occurrence of rice stripe leaf blight in the Lixiahe area of ​​Jiangsu Province has been increasing year by year. In 2004, the outbreak of the disease was widespread. Large-scale paddy rice generally reduced production and reduced the yield. In order to study the resistance of the main japonica rice varieties in the region to stripe disease, the varieties with better comprehensive traits (high yield, high quality, multi-resistance, etc.) were screened and used as the dominant varieties of rice in large area.
