摘要
以病区时空动态效应强度检验为核心,以纬度病圃、抗谱测定和抗性信息流的追踪考证作为持久抗瘟性鉴定评价方法的基础。经综合评价,认为特特勃(Tetep)、小粒野生稻Oryzaminuta J.S.Presl ex C.B.Presl、湘资3150、天津野生稻、谷梅二号、魔王谷等具有持久抗瘟性,可作抗源用,其中小粒野生稻兼具持久抗褐飞虱Nilaparvata lugens St(?)l性能;提出了持久抗瘟性鉴定的原则和方法。对持久抗瘟性的时空动态特性、广谱抗性与持久抗性的关系等进行了讨论。
Tetep,Oryza minuta J. S. Presl ex C. B. Presl, Tianjin Yeshengdao, Xiangzi 3150,Gumei 2 and Mowanggu with durable blast resistance have been integrally evaluated through tests of rice blast nurseries, the resistant spectrum and textural research of
the information of blast resistance. O. minuta persistently resists Nilaparvata lugens Stal as well. The different principles and methods of identification of durable blast resistance were suggested in the paper. Characteristics of time and space trends of durable blast resistance, the relationships between broad spectrum of resistance and the durable resistance were also discussed in this paper.
