The present study will generate significant information in terms of phenotypic and genotypic variability in the isolates of F. oxysporum f. sp. ciceris, wilt pathogen of chickpea collected from different geographical locations, which could be used further for development of area specific resistant varieties of chickpea. The accurate and rapid identification of pathogen is essential for all aspects of plant pathology from fundamental research on the biology of pathogens to the appropriate management of this disease. Cost effective molecular diagnostic kit (DArT) will be developed to study the variability in F. oxysporum f. sp. ciceris of chickpea. In addition, identification of rapid and cost effective molecular markers such as DArT will make the chickpea breeding activities faster for wilt resistance and the economic gains obtained will be large. Data generated with DArT markers will be compared with phenotypic data and analyzed using bioinformatics tools. Further, identification of molecular markers could lead to quicker assessment of susceptibility, allow screening of seeds or seedlings, and reduce the need for maintaining virulent isolates of the wilt pathogen.
