Abstract: The characteristics and inheritance for resistance to brown planthopper, Nilaparvata lugens (BPH) of 94-42-5-1, derived from Oryza rufipogon have been studied. Results showed that 94-42-5-1 had very high and broad spectrum resistance to BPH biotype 2, biotypes Pantnagar (India) and Cuulong (Vietnam). The latter two biotypes are highly virulent to rice. The line 94-42-5-1 was highly resistant to all the three BPH biotypes and higher than any other tested varieties with known resistance genes used. It is one of the high BPH resistance resources with AA genome. Inheritance analysis showed that the resistance of 94 42 5 1 to Cuulong biotype was conferred by two recessive genes with duplicate nature and one single recessive to Pantnagar biotype.

摘要： 研究了普通野生稻(Oryza rufipogon Griff.)株系94-42-5-1对稻褐飞虱(Nilaparvata lugens Stal)的抗性及其遗传规律。94-42-5-1高抗稻褐飞虱生物型2、印度潘特纳加生物型和越南九龙江生物型，其抗性均达到高抗1级，具有对稻褐飞虱抗谱广、抗性强的特点，是在AA染色体组稻种资源中发现的高抗稻褐飞虱抗源之一。抗性遗传分析表明，94-42-5-1对潘特纳加生物型的抗性为1对隐性基因遗传，对九龙江生物型的抗性受2对互相独立的隐性重复基因控制。
