Artificial inoculation technique for peanut stem rot caused by Sclerotium rolfsii and evaluation resistance of peanut seedling in greenhouse
摘要
Abstract
Artificial inoculation technique for peanut stem rot (caused by Sclerotium rolfsii Sacc. )was estab-lished in greenhouse. The results showed that the most efficient inoculations were with oat inoculum to stem base and to soil surface. The inoculation with oat inoculum to soil surface was more convenient in manipulation. There was no significant difference of disease index among peanut seedlings after inoculated with different dosage of oat inoculum of S. rolfsii,and the highest disease index was found in inoculation with four oat inoculums. There was no significant difference of disease index among the seedlings inoculated at 15 - 35days after planting (DAP)with the same oat inoculums. The inoculation technique established in this paper could induce peanut stem rot efficiently,and the dis-ease incidence and disease index were 100% and 89. 2 respectively. The resistance to peanut stem rot of nineteen peanut varieties/ lines were evaluated by this technique and only Zhonghua 16 showed moderate resistance,while others were medium to highly susceptible.关键词
