Abstract
Greenhouse experiment was conducted to evaluate suitability of four potato
cultivars i.e. Cara, Draga, Spunta and Solana against M. incognita infection at
20±3°C. Results indicated that none of the tested potato cultivars was immune to
nematode infection since galls or egg masses on root system of such cultivar was
recorded and all plant growth parameters were obviously diminished. Among the
tested potato cultivars, Spunta showed the highest percentage reduction values of
all plant growth characters. Host category of the tested cultivars was determined
according to the relationship between host growth response in term of reduction %
of whole plant fresh weight and R Factor recorded that Cara and Draga potato
cultivars were classified as moderately resistant (MR), whilst potato cvs. Spunta and
Solana were rated as highly susceptible (HS) and susceptible (S), respectively.
