| Abstract | ||
| Survey of eggplant fields showed that 93.33% of the fields were infected with root– knot nematodes , the mean of the infection was 33.33% in these fields reaching it’s maximum value (51.66% ) in the fields of Salamia area while it’s minimum value was 16.66% in the fields of Mosul area . The highest population density of nematode was found in the soil of one of the fields of Rabee’a area and the lowest in another field in the same area . Distribution of root–knot nematode species in eggplant fieids showed the presence of M.javanica and M. incognita .The former one was more widespread . Susceptibility of eggplant cultivars against M. javanica revealed that the cultivars differed among themselves.The cultivar Alton Kopri was the most susceptibile one, while Black beauty was with medium resistance. M.javanica completed its lifecycle in the roots of cultivars Al-Ton Kobri, Asil Zakholi (local) and Syrian in 27,30 and 32 days respectively, while nematode could not complete its life cycle in the roots of Tarhi and Black beauty cultivers. | ||
