Investigation of the development of root lesion nematodes (Pratylenchus thornei, P. neglectus, P. penetrans) on different chickpea variesties

In this study, population growth and reproduction rates of root lesion nematodes, Pratylenchus thornei, Pratylenchus neglectus and Pratylenchus penetrans on Bari 2, Bari 3 (Cicer reticulatum) and Cermi (C. echinospermum) chickpea varieties were investigated in the climatic chamber conditions. Pratylenchus thornei reached the highest population density on Cermi variety within 21 days, also on Bari 3 variety within 42 days, and Pratylenchus thornei did not grow on Bari 2 variety. Pratylenchus neglectus reached the highest population density on Cermi and Bari 3 varieties within 28 days. Pratylenchus penetrans reached the highest population density on the variety Bari 3 within 49 days while Bari 2 and Cermi cultivars showed low population densities during the trial period. Considering the reproduction rates of the root lesion nematodes in the tested varieties, Bari 2 cultivar is determined as resistant to Pratylenchus thornei and Pratylenchus neglectus and susceptible to Pratylenchus penetrans; Bari 3 variety is determined as resistant to Pratylenchus thornei, sensitive to Pratylenchus neglectus and Pratylenchus penetrans, while Cermi is sensitive to Pratylenchus thornei and Pratylenchus neglectus and moderately resistant to Pratylenchus penetrans.
