Cultivar reactions of the most nine common commercial cultivars of potato were tested under greenhouse conditions of plant pathology research Institute, ARC-Giza. The nine tested cultivars were divided to three groups . Lady Rosella was the most susceptible cultivar followed by Monalisa and Mondial cvs. Spounta , Nicola and Hemez cultivars showed moderate susceptibility, While Draga followed by Kara and Diamond were the most resistant UR - http://nile.enal.sci.eg/EALE/2009/MUJAS/3409/6/B/6941.pdf ER -
