Abstract
Twelve varieties of anthurium were evaluated to determine genetic variability, heritability and genetic advance. Analysis of Variance revealed that magnitude of the Phenotypic Coefficient of Variation (PCV) was higher than Genotypic Coefficient of Variation (GCV) for all the traits. High level of GCV (41.46) and PCV (41.91) were recorded for spadix length, whereas high level of PCV was also recorded for number of suckers per plant (30.88) followed by leaf width (30.50). High heritability was recorded for plant height (99.08) followed by inflorescence stalk length (98.82), petiole length (98.40), spadix length (97.88), water uptake (93.95), leaf width (93.51), leaf length (89.00) , spathe width (91.94), plant spread (87.36), number of suckers per plant (82.72) and spathe length (81.91). High heritability coupled with high genetic advance as per cent of mean was recorded for plant height, petiole length, leaf width, spadix length, number of suckers per plant and inflorescence stalk length showing greater chances of improvement through breeding programme.
