摘要：

Chickpea is an important cool-season food legume grown and consumed throughout the world. Amongst various biotic stresses which affect chickpea production, wilt caused by Fusarium oxysporum is one of the important diseases. Over the years, different races of this pathogen have been identified and characterized. Because of the significance of this disease, it is a prerequisite that the chickpea genotypes (both new as well as old) must be evaluated for their reaction against wilt before they are released as a new variety. In the present study, 31 chickpea genotypes comprising promising lines and earlier released varieties were evaluated for wilt resistance in the wilt sick plot. In addition, 18 SSR markers, which were earlier reported to be linked with wilt resistance QTLs were used to characterize these genotypes. The wilt reaction ranged from resistant [0% (WR 315) to 10% (PG 15,016, Vijay)] to highly susceptible type [53.33% (BG 3065; NDG 14–11) to 100% (JG 62)]. It was observed that majority of the lines from North India were susceptible to wilt, while those from the state of Maharashtra (western India) were resistant indicating that the genotypes from different parts of India have resistance against different races which are prevalent in different regions. It was also observed that molecular markers could group these chickpea genotypes largely based on their reaction against wilt and to some extent on the basis of their pedigree. © 2020, Indian Phytopathological Society.
