بررسی و تعیین ارقام پسته اهلی ‭(Pistacia vera) ‬مقاوم به نماتود مولد غده ریشه

Root-knot nematodes (Meloidogyne spp.) have been recognized as the most important group of plant parasitic nematodes in the world. Because of world-wide distribution and wide host range, this genus causes severe damages on Agricultural crops. Root-knot nematodes are an important pathogen of pistachio trees in pistachio growing areas of the world. One of the best methods to control root-knot nematods is using of resistant cultivars. To evaluate the reaction of pistachio cultivars to the pathogen (Meloidogyne javanica), seeds of nine commercial pistachio cultivars including : Akbari, Owhadi, Ahmadaghaii, Shahpasand, Mollasakineh, Aliabadi, Abbasali, Khanjari and FAS-16-74, were collected from pistachio growing areas in Rafsanjan and Damghan. The seeds were sown in the infected field with M. javanica. Experiment was conducted under complet randomized block design with three replications. Each replicate contained 10 seedlings. one year after plantation, gall index and the population of M. javanica parameters were examined. On the basis of the Taylor and Sasser (1978) method, there was no resistant cultivar.
