Description
Summary:This investigation was conducted on experimental farm, Faculty of Agriculture, Al-Azhar University, Assiut Branch, Assiut, Egypt during the summer plantings of 2011 and 2012 to test susceptibility of 14 Okra genotypes for resistance and to powdery mildew disease caused by Erysiphe cichoracearum and for their yield and yield-components under the agro-climatic conditions of Assiut, Egypt. All screened genotypes showed varied degrees of susceptibility to the artificial inoculation with the tested pathogen. Data found here indicated that some varieties e.g. Beheira, A-Aiat,Giza (a), Seds, Beni-Suef landraces and Gold Coast cultivar are more tolerant to powdery mildew disease. The others were varied from highly susceptible to moderate susceptible. The most susceptible genotype was Pusa Sawani in both seasons. On the other hand, Pusa Sawani and Gold Coast cultivars recorded higher values for yield and its components in both tested seasons. The results showed that Beheira, A-Aiat,Giza (a), Seds, Beni-Suef landraces, Gold Coast and Pusa Sawani cultivar could be wed as a good genetic resources in okra breeding programs for powdery mildew disease resistance and yield.
