The study investigated the status of cereal cyst nematodes (CCN) in the main wheat-growing areas of Kyrgyzstan in 2020. Soil samples were taken from 69 different wheat fields located in Chuy and Issyk-Kul provinces. CCN were found in thirty-one out of the sixty-nine locations surveyed. The highest occurrence of CCN was in the Tyup location in Issyk-Kul province with 81 cysts (250 cm3 soil)-1. The CCN populations were identified by both morphological and molecular analyses. According to the results, all populations were identified as Heterodera filipjevi. No variations in rDNA-ITS sequencing da ...Daha fazlası
