| 摘 要： | 室内试验用 2种方法测定马铃薯晚疫病菌的寄生适合度。结果表明 :复合指数法更适用于此病原物。从品种看 ,米拉表现最抗病 ,其次是坝薯 10号、一墩青和克疫 ,克新 1号、无花和坝薯 9号较感病 ,费乌瑞它和紫山药最感病。从菌种看 ,C5的致病性普遍高于C2 ,而C2的致病性又普遍高于C4。 |

STUDIES ON METHODS ESTIMATING THE PARASITIC FITNESS OF Phytophora infestans(Montgne) de Bary ⅡGEENHOUSE EXPERIMENT |
|
| Abstract: | In greenhouse experiment,two methods were used to estimate the parasitic fitness of Phytophthora infestans(Montagne)de Bary.The results showed that composite fitness index was more suitble for this pathogen.Among cultivatrs,the resistance of Mira to P.infestans(Montagne)de Bary was found to be the highest.The next were Bashu No.10,Yidunqing and Kuannae and the resistnace of Kexin No.1,Wuhua and Bashu No.9 was lower than that of the former?The resistance of Favorita and Purple Yam(Zishanyao)was the lowest.As to isolates,it was found that the pathogenicity of C5 was generally higher than that of C2,and that of C2 was generally higher than that of C4. |
