Abstract
Wilt (Fusarium oxysporum f. sp. ciceris) is considered as one of the major factors for low productivity of chickpea (Cicer arietinum). The present study was conducted to determine pathogenic and genetic variability of isolates of F. oxysporum f. sp. ciceris collected from different parts of India. Pathogenic virulence study of 25 isolates of the pathogen on international set of differential cultivars revealed the existence of three new races of the pathogen in India, besides characterization of new isolates in the known four races of the pathogen. Genetic variability within 24 isolates representing seven races of F. oxysporum f. sp. ciceris was assessed by RAPD, with a set of 40 ten-mer primers. UPGMA cluster analysis divided the isolates into seven distinct clusters at 0.55 genetic similarities. The most virulent isolate obtained from wilt sick field of IARI (MB-4C), New Delhi was distinct from others.
