Abstract:
An experiment was conducted with 30 genotypes of lilium to study the genotypic and phenotypic coefficients of variation, heritability and expected genetic advance. The data indicated that estimates of phenotypic coefficient of variation (PCV) is greater than those of genotypic coefficient of variation (GCV) for all the traits studied indicating apparent variation is not only due to genotypes but also due to the influence of environment. High heritability coupled with high genetic advance were observed for most of the traits indicating the presence of additive gene action. High estimates of GCV (>20%), PCV (>20%), heritability (>60%) and genetic advance over mean (>20%) were obtained for days to bulb sprouting, plant height at 60 days after planting, number of leaves, leaf area index, total chlorophyll, flowering duration, stalk length, stalk diameter, florets per stalk, stalks per square meter and bulbs per plant showing that selection of these characters may be relied upon for pure line selection for improvement.
