摘要： Screening of 94-42-5-1, a derivative of wild Oryza rufipogon (Griff.) accession revealed its high resistance against three brown planthopper (]BPH) biotypes from the predominantly rice-growing regions of Asia, viz. biotype 2, Cuulong (Vietnam) and Pantnagar (India), the latter two being the most virulent. Inheritance studies indicated the nature of its resistance to be monogenic recessive against the Pantnagar biotype and digenic recessive against Cuulong biotype. One of the two recessive resistance genes was allelic to bph4, while the other was non-allelic with all other known BPH resistance genes of cultivated species O. sativa L. The new source with the AA genome identical to the cultivated rice, would have great potential in combating the problem for BPH resistance in cultivated rice. [References: 11]
