摘要
通过喷雾接种具有鉴别能力的稻瘟菌生理小种037、007、033、035、017、333、137、101,根据病斑型推断部分水稻品种的稻瘟病真抗性基因型.基因型为十的是合江11号、合江12号、合江13号;pi—i的是合江14号;pi—k的是龙粳1号;pi—km的是合江22号;pi—api—i的是合江18号;pi—ipi—k的是合江19号;pi—api—ta的是合江20号、东农85—08:pi—ipi—km的是合江23号.pi—api—k的是东农78—24.
The genotypes of true resistance to blast of some main cultivars of Heilongjiang province were tested by spray inoculating with the physiological races of Piricularia oryzae with the ability to differentiate the resistant genes to blast namely: 037、007、033、035、017、333、137、101. The results were infered by types of lesions. Genotype+ : Hejiang 11,Hejiang 12, Hejiang 13; genotype Pi-i:Hejiang 14; genotype pi-k: Longgen 1; Genotype pi-km:Hejiang 22;pi-a pi-i: Hejiang 18; pi-i pi-k: Hejiang 19,pi-a pi-ta: Hejiang20; Dongnong 85-08, pi-i pi-km: Hejiang 23; pi-a pi-k: Dongnong 78-24.
