Morphological and Molecular Characterization of () Populations Parasitizing Pistachio in Kerman and Khorasan Razavi Provinces, Iran.

Root-knot nematodes (RKNs) are the most destructive nematode species in main pistachio cultivation areas of Iran, and adversely affect crop quality and yield. So far, and have been reported infecting pistachio. In this study, four populations of were found infecting pistachio in Kerman and Khorasan Razavi provinces.

Penetration and Development of on Four Pistachio Rootstocks and their Defense Responses.

Pistachio yield is annually reduced due to root-knot nematode infections. In order to evaluate its resistance to , three domestic pistachio rootstocks, namely, Badami, Ghazvini and Sarakhs, and a wild pistachio, Baneh ( subsp. ), were selected.
