稻瘟病(Pyricularia oryzae)和白叶枯病(Xanthomonas campestris PV.oryzae)是我国水稻的两个重要病害,常同田发生,培育和筛选双抗品种,为兼治两病最经济有效的措施。作者1975年从国外引进452个品种(系),经病圃和人工接种鉴定,初步筛选出75个抗叶瘟和穗颈瘟的品种,后经8年对稻瘟和白叶枯病的抗性鉴定及株选,至1984年选出抗两病的中迟熟品种12个(称“双抗品种”)。1985年从中选出7个参加全国水稻
Pyricularia oryzae and Xanthomonas campestris PV.oryzae are two important diseases of rice in our country. They often occur in the same field, cultivate and screen double-resistant varieties, which is the most economical and effective way to treat both diseases. In 1975, 452 varieties (lines) were introduced from abroad. After identification by nursery and artificial inoculation, 75 varieties of leaf blast and panicle blast were initially screened. After 8 years of resistance to blast and bacterial blight Sexual identification and selection of strains, to 1984, the selection of two disease resistant late varieties 12 (called “double anti-species”). Seventeen selected from them in 1985 to participate in the national rice
