1981～1990年,笔者以国际稻白叶枯病圃和褐稻虱圃的材料为主,先在历年各自抗性鉴定基础上,选出抗性材料进行交互抗性测定.结果表明.在784个品种中,具有双抗品种327个,可作水稻兼抗甚至多抗育种的抗性供体亲本利用.
From 1981 to 1990, the author focused on the material of the international rice leaf blight nursery and brown rice nursery nursery. Based on the identification of their respective resistances over the years, the authors selected the resistant materials for cross-resistance testing. The results showed that in 784 Among the cultivars, there were 327 pairs of double-resistant cultivars, which could be used as parents of resistant donors for breeding of rice with anti-resistance and even multiple resistance.
