摘　　要：本研究旨在评估来自17个省(市)的粳稻品种在云南省的稻瘟病抗性差异,并筛选出具有优异稻瘟病抗性的资源。通过田间病圃自然诱发的方法,对1050份粳稻品种进行叶瘟和穗瘟的抗性鉴定。研究结果显示,叶瘟发病轻而穗瘟发病较重;在叶瘟方面,表现出高抗、抗、中抗、中感、感和高感的品种分别占28.48%、10.95%、9.14%、19.24%、20.00%和12.19%;而在穗瘟方面,表现出高抗、抗、中抗、中感、感和高感的品种分别占3.71%、0.38%、2.57%、19.62%、22.57%和51.14%;进一步对叶、穗瘟结果进行分析,发现有69份既抗叶瘟又抗穗瘟的水稻品种,这69份粳稻品种来源于吉林、黑龙江、辽宁、云南和江苏等5个省。研究结果表明,在田间叶瘟和穗瘟抗性表现较好的这些材料可为抗稻瘟病育种以及抗稻瘟病新基因发掘提供重要的抗源。In order to compare the differences of resistance to rice blast disease in Yunnan among japonica rice cultivars collected from 17 provinces,and to screen favorable resistant resources of rice,we employed the method of natural induction in field blast nursery to assess the resistance of 1050 japonica rice cultivars against leaf and panicle blast.The results indicated that among the 1050 japonica rice cultivars,there was lighter incidence of leaf blast and more severe incidence of panicle blast.Regarding leaf blast resistance,the cultivars exhibiting high resistance,resistance,moderate resistance,moderate susceptibility,susceptibility,and high susceptibility accounted for 28.48%,10.95%,9.14%,19.24%,20.00%,and 12.19%,respectively.As for panicle blast resistance,the cultivars exhibiting high resistance,resistance,moderate resistance,moderate susceptibility,susceptibility,and high susceptibility accounted for 3.71%,0.38%,2.57%,19.62%,22.57%,and 51.14%,respectively.Further analysis of the leaf and panicle blast results revealed that 69 japonica rice cultivars had resistance to both leaf and panicle blast.These 69 cultivars were collected from five provinces of Jilin,Heilongjiang,Liaoning,Yunnan,and Jiangsu.These results suggested that these cultivars with good resistance against both leaf and panicle blast in blast nursery could be served as important resistance resources for blast disease-resistant rice breeding,and discovery of new genes conferring resistance to rice blast.
