以浙江省11个粳稻品种(系)对条纹叶枯病抗性进行自然鉴定,并进而用一个与水稻条纹叶枯病抗性基因Stvb-i紧密连锁的RM209微卫星标记进行了分子检测。结果表明,春江051、丙00502SJ、丙00502HSF47、HGP5和HPG6共5个水稻品种(系)检测到Stvbi-抗性基因,其中丙00502HSF47田间表现感病,其它4个品种(系)均表现出良好的田间抗性。Z5、HGP3和HGP4虽未检测到Stvb-i抗性基因,但也表现出较强的田间抗性,推测这3个品种可能含有新的抗病基因或具有其它某种抗病机制。 The resistance to stripe virus was identified from 11 japonica rice varieties in Zhejiang Province. The molecular markers were detected by a RM209 microsatellite marker closely linked to rice stripe virus resistance gene Stvb-i. The results showed that Stvbi-resistance gene was detected in 5 rice varieties (lines) of spring 051, prop 00502SJ, prop 00502 HSF47, HGP5 and HPG6, of which, 00382 HSF47 was susceptible to the disease and the other 4 lines showed good Field resistance. Although there were no Stvb-i resistance genes detected in Z5, HGP3 and HGP4, they also showed strong resistance in the field. It is speculated that these three cultivars may contain new disease-resistance genes or some other disease-resistant mechanisms.
