摘要
为了明确宁夏固原市马铃薯主栽品种对晚疫病的抗性,采用田间自然发病的方法对20个主栽品种开展了抗病性研究。结果显示,抗病性最强的品种是宁薯12号,其次为冀张薯5号、虎头、费乌瑞它、陇薯3号,它们在发病初期的病情指数为0.44～0.80,发病中期的介于0.98～1.50。综合抗病性、产量和商品薯率对品种优劣进行了排序,结果表明,综合性状表现最好的是冀张薯5号,其次为宁薯12号、陇薯3号、地希瑞、虎头。生产中应同时注重品种抗病性以及产量、商品薯率等经济性状,进行合理布局。
This experiment investigated the disease resistance condition of 20 main potato cultivars to late blight in Guyuan,Ningxia,using the method of investigation in the field.The results indicated that Ningshu No.12 was the most resistant of all,followed by Jizhangshu No.5,Hutou,Feiwuruita and Longshu No.3.The disease index of the cultivars above was 0.44-0.80 in early stage,and 0.98-1.50 in middle stage.Then the study contrasted the composite characters of resistance,yield and commodity potato rate,and results indicated that Jizhangshu No.5 was the best of all in composite characters and the next was Ningshu No.12,and then Longshu No.3,Dixirui and Hutou.In production,famers should pay attention to disease resistance,yields,commodity potato rates and other economic traits of potato cultivars at the same time,to give rational distribution of cultivars.
