摘要
采用人工病圃测定方法评价了57份生姜品种对茎腐病的抗性。结果表明,生姜不同品种及其不同生育期对茎腐病的抗性差异显著。依据生姜收获前期的病情指数,参试品种可分为中抗、中感、感病和高感等4种抗性类型。其中,中抗类型只有广西大姜1个品种,中感类型包括湖南隆回虎爪姜1、井冈山姜和鲁中大姜等26个品种,感病类型包括浙江瑞安大姜、福建大姜和广西姜等23个品种,高感类型包括台湾肥姜、四川西坝姜和Z102等7个品种。研究没有发现高抗、抗病品种。
The resistance of 57 ginger varieties to stem rot were evaluated by artificial disease nursery method.The results showed that the resistance varied significantly between different varieties and different growth periods of ginger.According to the disease index in early harvest time,the tested varieties could be di-vided into 4 types including moderately resistant（MR）,moderately susceptible（MS）,susceptible（S）and highly susceptible （HS）.Among them,the MR type contained only one variety（Guangxi ginger）;the MS type contained 26 varieties such as Longzhua ginger 1 from Longhui of Hunan,Jinggangshan ginger and Luzhong ginger;the S type contained 23 varieties such as Ruian ginger of Zhejiang,Fujian ginger and Guangxi ginger;and the HS type contained 7 varieties such as Taiwan ginger,Xiba ginger of Sichuan and Z102.The highly -resistant and resistant varieties were not found in this study.
