Identification of the Pathogen of Root Rot and Evaluation of Disease Resistant Varieties of Carrot
Root rot is a serious disease in the main production area of carrots in Inner Mongolia.In order to identify the pathogen and screen out resistant varieties,the pathogens were isolated by using tissue isolation method,pathogenicity was determined by using fleshy root inoculation method,and the pathogens were identified through morphological and molecular biology methods.The disease resistances of root rot of 20 varieties commonly used in the main production area were evaluated.The results showed that the pathogen of carrot root rot in the Ulanqab area of Inner Mongolia was Fusarium solani,and one highly resistant variety('Huanai No.7')was selected from the tested varieties.The findings provided the exploration of carrot root rot resistance genes and the selection of carrot resistant varieties.
