| description | An assay based on electrolyte leakage (LEA) from callus tissue of Solanum spp. treated with culture filtrates of Verticillium dahliae was useful for screening eggplant genotypes for resistance to Verticillium wilt. Loss of electrolytes from the most resistant genotypes was significantly lower than that from the susceptible genotypes when callus tissue was incubated with a 10% filtrate solution of the virulent isolate 122. No difference was detected with filtrate solutions of the avirulent isolate 809 of the fungus. Among the tested genotypes, the S. melongena lines CCR3 and SM19/14 and the wild species S. torvum were the most resistant in the glasshouse tests and released the smallest amounts of electrolytes. The most susceptible cultivars, Lunga Violetta and Giant of China, produced the greatest leakage of electrolytes. LEA performed on stem segments failed to distinguish between susceptible and resistant genotypes of eggplant. |
