Abstract

Evaluation of sixteen potato (Solanum tuberosum) cultivars (Banba, Belleni, Bresius, Burren, Cara, Diamant, Hermes, Kuras, Lady Balfour, Lady Rosetta, Metro, Mondial, Solana, Synergy, Spunta and Strux) for their susceptibility and resistance against both Meloidogyne javanica and Rotylenchulus reniformis infection was tested under greenhouse conditions. The behavior of both nematode species was greatly governed by the tested cultivars. None of the potato cultivars was immune host for both nematode species infection. M. javanica succeeded in invading and developing on all tested potato cultivars except Kuras and Solana cvs. which were considered as highly resistant and moderately susceptible hosts, respectively. On the other hand, Belleni, Bresius, Hermes, Lady Rosetta, Solana, and Synergy were ranked as highly resistant (HR) to R. reniformis, while the rest cultivars showed various degrees in their susceptibility to R. reniformis infection.
