Phytophthora root and stem rot of soybean is a destructive disease of soybean in Iran. During 1998-2005, 142 isolates from soil and diseased soybean plants were collected and tested. Race identification was made possible by inoculating Rps differential soybean cultivars and lines. Of the 142 isolates tested, 110 isolates belonged to race 1 and 32 isolates belonged to race 3. Race 1 was dominant in soil and diseased plant samples. There was no variability in virulence of Phytophthora sojae between the areas surveyed.

Zgnilizna korzeni i pędów soi jest destruktywną chorobą w Iranie. W latach 1998-2005 wyosobniono i przetestowano 142 izolaty pochodzące z gleby oraz chorych roślin. Rasy patogena oznaczano przeprowadzając inokulację odmian i linii soi wchodzących w skład zestawu różnicującego. Ze 142 przetestowanych izolatów - 110 zaliczono do rasy 1, a 32 izolaty do rasy 3. W glebie oraz próbach materiału roślinnego dominowały izolaty rasy 1. Na badanym terenie nie stwierdzono zmienności wirulencji Phytophthora sojae.
