| 摘 要： | 针对广东褐稻虱生物型致害力增强和抗性品种抗性减退的现状,对从国际水稻研究所引进的抗褐稻虱水稻种质资源进行抗性鉴定与评价.结果表明,在174份鉴定材料中,获得5份高抗种质,8份中抗种质.同时还进行抗性单株系筛选,通过抗性鉴定、单株繁育和株系抗性鉴定,获得了对广东高致害力褐稻虱种群具有较高抗性的株系11个,这将为广东的抗褐...

| Abstract: | As the enhancement of virulence of Guangdong native BPH biotype and abatement of rice varieties' pest resistance,resistant evaluation of rice resistant varieties to BPH which had been imported from IRRI had been studied.The experiments results showed that five high resistant lines and eight middle resistant lines from 174 unidentified materials were found.Moreover,through the trials about resistance identification,individual breeding and resistant identification of strains,eleven high resistant strains to G... |
