水稻白叶枯病是水稻危害最严重的病害之一。浙江省的水稻白叶枯病菌有Ⅰ—Ⅶ7个致病型,存在着致病力极强的Ⅱ型菌。我国水稻抗病品种抗源单一,大面积种植单一抗源品种有引起病害大流行的危险,因而寻找新的抗源已显得十分重要。利用野生稻来扩大栽培稻的遗传资源和强化其抗病性是水稻品种改良面临的一项重要任务。疣粒野生稻是我国现存的3种野生稻之一,经湖南省
Rice bacterial blight is one of the most damaging diseases of rice. There are 7 pathogenic types Ⅰ-Ⅶ of Xanthomonas oryzae in Zhejiang Province, and there is a highly pathogenic type Ⅱ bacteria. It is very important to search for a new source of resistance in our country, where the resistant varieties of rice are single-sourced and single-sourced varieties are planted in a large area, causing the risk of disease pandemic. The use of wild rice to increase the genetic resources of cultivated rice and to strengthen its disease resistance is an important task facing rice varieties. Warty wild rice is one of the three existing wild rice species in our country, which passes through Hunan Province
