Screening twenty genotypes of carnation for resistance against two isolatesviz., IIHR and Pune of Fusarium oxysporumf. sp. dianthi, revealed that the genotypes varied in their response to the presence of the pathogen. It was observed that the genotype Loris, took the least number of days for first symptom appearance in both IIHR (39.5 days) and Pune isolates (38.5 days), whereas, the genotype Gioele took the highest number of days for the isolate IIHR (60 days) and the genotype Praga for the isolate Pune (57 days). In addition, the genotype Praga recorded the least per cent disease incidence for both IIHR (24.99 %) and Pune (16.66 %) isolates and also the least disease severity for both IIHR (8.56 %) and Pune (8.98 %) isolates.
