Abstract:
Anthurium andreanum, belongs to the family Araceae is one of the most important cutflower crop in the world and is having a high commercial value. This study was conducted with the objective in identifying the commercially superior Anthurium genotypes, through genetic variability parameters. For the present investigation, twenty commercially significant Anthurium genotypes were considered. The characters examined for the study included both vegetative and floral characters viz., number of spadices, spathe size, spathe length, number of flowers per spadix etc. On analysing the analysis of variance, significant variations were observed for all the characters studied. The character, spadix length and size were noticed to be the highest in the genotype Acropolis White and the genotype Ordinary Orange recorded the highest mean value for the character, number of flowers per spadix. The phenotypic coefficient of variation (PCV) of all characters were found to exhibit a higher value than genotypic coefficient of variation (GCV) indicating the influence of environmental factors. The character, number of suckers/plants recorded high PCV and GCV value. High heritability coupled with high Genetic advance was noticed in the characters spathe size and number of flowers per spadix which indicates that these characters are under additive gene action and are less affected by environmental factors. Selection based of phenotype can be advised for the improvement of these characters.
