Abstract

Tanha Maafi  Z. & Heidari R. 2015. Review on incidence of soybean cyst nematode in Iran. Plant Pathology Science 4(2):1-16.

Soybean cyst nematode, Heterodera glycines, is widespread in major soybean producing countries and is considered as the most suppressed agent of soybean yield in the world. This nematode was reported from northern Iran in 1999 for the first time. Presently SCN is widely distributed in Golestan and Mazandaran provinces and infestation rate is a remarkable showing broad range of infestation. In most fields, the population density is above the damage threshold level reported for this nematode in the literatures. The HG Type 0 (race 3) has been defined as the dominant type in the region and Katoul (DPX) is the only resistant cultivar to this type of SCN in Iran. Importance of soybean cyst nematode, distribution and severity of infection, nematode morphology, symptoms, race/Hg Type, life cycle, reaction of Iranian cultivars against the dominant SCN Hg Type in Iran, and its management, based on the researches conducted in Iran and in the world are presented in this paper.
