Abstract

Genotypes grown in multi-environmental trials may respond differently to a range of climatic factors, soil characteristics and cultural management practices. As such, the proportion of the variation in the phenotypic traits due to the main effects of genotype, environment and their interaction is routinely assessed when selecting best-performing lines. Keeping this in mind, the present study was carried out to find the stable Lilium genotypes evaluated over two locations for two years in a Randomized Block Design along with three replications. Eighteen diverse genotypes of Lilium were assessed for twenty different vegetative, flowering and bulb parameters. Genotype “Eyeliner” indicated stability for the majority of parameters, including days to bulb sprout emergence, bud length, number of flowers/stem, weight of bulblets, and vase life, while genotype “Yelloween” exhibited stability for a variety of parameters, including leaf length, bud length, size of flower, and days to first flower, and is suitable for a variety of environments.
