The study was conducted on performance of eighteen genotypes of glory lily (Gloriosa superbaL.) against leaf blight disease under Tamil Nadu conditions. Experiment was laid out in a randomized block design with three replications at the Medicinal Plants Unit, Botanical Garden, Tamil Nadu Agricultural University, Coimbatore. All genotypes expressed significant variations for percent disease index and varied from 21.73 to 64.48%. The genotype GS 07 and genotype GS 05 exhibited the lowest index (21.73%) and highest index (64.48%), respectively. The percent disease index exhibited highly positive significant correlation both at phenotypic and genotypic levels for polyphenol oxidase. But it had negative significant association with peroxidase, total phenol content and catalase activity. The genotype GS 07 exhibited the lowest PDI value and this genotype considered as tolerant to leaf blight.
