1978—1984年,作者对来自国内外不同生态条件下的7,344份水稻品种资源,在苗期或成株期,用人工接种的方法,对稱瘟病、白叶枯病和褐稻虱的抗性进行了鉴定,结果表明:同时抗上述两病一虫的有BG379—3、IR26和IR36等181份品种(系),占2.5％。这些品种主要是由国际水稻研究所提供的籼稻型品种(系)。在粳稻型品种中尚未发现同时能抗上述两病一虫者。王齐头、红禾和农虎4号等2,084份品种(系),对上述两病一虫均无抗性,这些主要是中国品种,占28.4％。对褐稻虱具有抗性的,主要是国外的籼稻型品种,粳稻型品种几乎全感此虫。抗稻瘟病的品种也以籼稻型品种为主,并且抗性较强;粳稻型的品种抗性较弱,在来自云南省的陆稻品种中抗稻瘟病的比例高。抗白叶枯病的以粳稻型品种居多,而且抗性强;宽叶类型籼稻品种易感此病。
In 1978-1984, the authors studied the resistance of 7,344 rice cultivars under different ecological conditions at home and abroad to artificial blast, bacterial blight and brown planthopper at the seedling or adult stage by artificial inoculation The results showed that there were 181 varieties (lines) of BG379-3, IR26 and IR36, which accounted for 2.5% of the total. These varieties are mainly indica rice varieties (lines) provided by the International Rice Research Institute. In japonica rice varieties have not been found at the same time be able to fight these two diseases and insects. 2,084 varieties (lines) such as Wangqitou, Honghe and Nonghu 4 were resistant to the above two diseases and one insects. These were mainly Chinese varieties, accounting for 28.4%. Resistant to brown planthopper, mainly foreign varieties of indica rice, japonica rice varieties almost full sense of this insect. Rice cultivars resistant to blast were also mainly indica rice cultivars with strong resistance. Japonica rice cultivars with low resistance were highly resistant to rice blast in Upland rice varieties from Yunnan. Bacterial blight resistance to japonica rice varieties are mostly resistant and resistant; wide-leaf type Indica rice varieties susceptible to the disease.
