Abstract: (78 Views)
Cereal cyst nematode is acknowledged globally as a biotic constraint for wheat production in the world. A total of 150 composite soil and root samples were randomly taken from wheat fields of Kohgiluyeh and Boyer-Ahmad province during 2016-2020, along with recording the geographical coordinates of the sampled locations. Species was identified based on morphological and morphometric features and molecular characters. Among 75 soil samples, from rain-fed and irrigated wheat fields of the province, 42 soil samples (56%) contained Heterodera filipjevi. The percentage of infested of rain-fed and irrigated wheat fields in the province was estimated to be 55 and 57.6 respectively, with 2.6 eggs and J2s/g of soil. The average population of eggs and second-stage juveniles (J2s) in cysts extracted from infested soils collected from wheat fields in the province was estimated as. The minimum population density of H. filipjevi (0.5 eggs and J2s/g of soil) was found in wheat fields of villages Tol Khosrow in Boyer-Ahmad county. The rain-fed wheat field (Dehdasht cultivar) of Lirab village in Basht county with 13.7 eggs and J2s/g of soil, has the highest mean population density of H. filipjevi. The average population of eggs and J2s in both rain-fed and irrigated wheat fields infested with the H. filipjevi in all counties of the province were estimated to be 2.6 and 2.51/g soil, respectively. In total rain-fed and irrigated wheat fields, the highest and lowest mean populations of eggs and J2s of H. filipjevi were 4.9 and 1.18, respectively, in Basht and Gachsaran counties.
