【摘要】 用菲律宾6个白叶枯病菌系（小种）,将95个水稻品种（品系）划分为5个品种类群,为今后开展品种抗病性的基因分析提供了必要的条件。通过测试,提出舟松62、二九丰（早籼） 城特232、T₈₅₂₈、H₁₀₁、6003、T₈₈₅₀₆、T₈₈₅₁₇、R₈₉₅、绍糯₈₈₄₃、丙₈₈₁₅₁、台₂₀₂、T₈₈₅₂₂（晚粳）等13个具有广谱抗性的品种（系）,可作杂交亲本利用。本文研究并探明了浙江省主要水稻品种对稻白叶枯病的抗性隶属,为有针对性的抗病育种、实现不同抗性基因的累加互补、有计划地培育多系品种和稳定持久的广谱抗性品种以及抗病良种在生产上的合理布局提供依据。更多还原

【Abstract】 By using six isolates(physiological races)of Xanthomonas campestrispv.oryzae.from Philippines.95 rice cultivars(lines) so far tested can bedistinguished in to 5 groups of genic cultivars.This will be the basis of fur-ther studies on the genetic analysis of disease resistance after repeatedtrials in accordance with reaction of resistance or susceptibility to ricebactreial blight(BB).The wide spectrum resistance to BB was involved in13 cultivars tested,such as Zhousong 62,Erjioufeng,Chengte 232 etc.whtchare able to resist various races and could be recommended as BB resistancesources for breeding.更多还原
