水稻对白叶枯病的抗病性反应因品种(系)而异,1977～1983年收集了生产上应用的主要品种、国内外引进的丰产抗病品种以及育种工作中筛选的丰产或抗病的品系材料共计5447个,经人工接种进行抗病性反应筛选。1977～1980年的工作已经报道(见《宁夏农业科技》1982年4期)。现将1981～1983年鉴定3258个材料的结果总结如下。鉴定试验过程参试品种(系)由本院作物所水稻室及品种资源室提供。1981～1982年鉴定试验田设在永宁县养和公社王太第四生产队的常年稻田,面积1.56亩;1983年原试验稻田分给专业户宋万珍,面积为1.2亩。
The resistance of rice to bacterial blight varied according to the varieties (lines). From 1977 to 1983, the main cultivars used for production were collected. The high-yielding and disease-resistant cultivars introduced at home and abroad, and the high yielding or disease-resistant A total of 5447 strains of materials, the artificial inoculation screening for disease resistance. Work from 1977 to 1980 has been reported (see “Ningxia Agricultural Science and Technology” 1982 the fourth period). The results of 3258 materials identified from 1981 to 1983 are summarized below. Identification of the test process Varieties (lines) by the Institute of crop rice room and variety resources room. From 1981 to 1982, the experimental field was located in the perennial paddy field of the fourth production team of Wang Tai, Yanghe County, Yongning County with an area of 1.56 mu. In 1983, the original experimental paddy field was allocated to Song Wanzhen, a specialized household with an area of 1.2 mu.
