| 摘 要： | 2004~2005年对福建省18个水稻新品种进行了苗期人工接菌和田间病圃自然诱发抗稻瘟病鉴定。结果表明,参试品种对1996年以前分离的稻瘟病菌株群体抗性水平高于2003和2004年分离的稻瘟病菌株。不同水稻产区采集的菌株对水稻新品种致病性有差异,以福建省的宁德、三明、龙岩三个地区的菌株致病性较强,水稻新品种室内苗瘟和田间穗颈瘟的鉴定结果较为一致。通过分析,认为宜香优673、D优15和冈优148三个水稻新品种抗病性较好,可考虑在生产上示范应用。 |

| Abstract: | From 2004 to 2005,identification of 18 rice new varieties resistant to Magnaporthe grisea were carried out by artificial inoculation in greenhouse and natural inducing in field in Fujian Province.The results showed that tested rice new varieties resistant to Magnaporthe grisea populations isolated before 1996 were higher than to ones isolated in 2003 and 2004.Rice blast fungi isolated from Ningde,Sanming,Longyan areas had stronger virulence to rice new varieties.Identifications results of rice cultivars resistant to seedling blasts in greenhouse was similar to neck blasts in field.By analysis and evaluation,resistance of rice varieties Yixiangyou673,Dyou15 and Gangyou148 were stronger,and could be applied in production. |
