Thirty nine isolates of Fusarium oxysporum f. sp. ciceris causal agent of chickpea (Cicer arietinum) wilt collected from the different parts of India representing eight races of the pathogen were used for the classification based on vegetative compatibility grouping (VCG). Three hundred and seventy nine (75.9%) nitrate non utilizing mutants generated on 2.5 % potassium chlorate medium were further divided into three classes, namely, nit1(73.3%), nit3(15.6%), and nitM (9.5%) based on utilization of various nitrogen sources. Nit mutants were paired to determine compatibility by varying degree of heterokaryon formation. Self incompatibility was observed in more than 50 % of the isolates. The isolates included in the present study were observed to be belonged to a single VCG (0280). Thus, in spite of variability in the virulence, the Indian population of the pathogen has only one VCG. |
