一份抗纹枯病水稻品种ZH5的抗病虫特性和生物学性状

两年的温室、大田人工接种和自然诱发等抗病虫鉴定结果表明，ZH5除抗纹枯病外，对稻瘟病、白叶枯病和稻飞虱也具有较好的抗性。生育期、株型观察和稻米外观品质分析表明，ZH5综合农艺性状好，具备“理想株型”的特征。由于具有优质、高产、多抗的特性，ZH5是无公害优质稻生产的理想品种，也是优质、多抗育种，特别是抗纹枯病育种的理想抗源材料。

Disease and Insect Pest Resistance and Agronomic Traits of Rice Variety ZH5 with Sheath Blight Resistance

An experiment on identification of disease and insect pest resistance was conducted through artificial and natural disease inoculations in greenhouse and fields in 2005 and 2006.The results indicated that ZH5 was resistant to rice sheath blight(Rhizoctonia solani),rice blast(Magnaporthe grisea),rice bacterial leaf blight(Xanthomonas campestris pv.oryzae)as well as the brown planthopper(Nilaparvata lugens).ZH5 showed good agronomic characters and ideal plant types.With high quality,high yield and multiple resistance,ZH5 is an ideal material for green and high quality rice production,and also for multiple-resistance rice breeding,especially for sheath blight-resistant rice breeding.
