Host Suitability of Four Potato Cultivars To Meloidogyne Incognita Infection Under Greenhouse Conditions
Journal Title: Egyptian Journal of Agronematology - Year 2017, Vol 16, Issue 1
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.
