Abstract: <em>Anthuriumandreanum</em> Linden, is one of the most commercially cultivated anthurium species belonging to the family Araceae. They are widely accepted as ornamental for their showy and colorful spadix. Fifteen <em>Anthuriumandreanum</em> Linden hybrids maintained at the Department of Plant Breeding and Genetics, College of Agriculture, Vellayani were utilized for the study. The hybrids were evaluated for commercially important characters and the genetic parameters contributing to these characters were analyzed. Phenotypic Coefficient of Variation (PCV), Genotypic Coefficient of Variation (GCV), heritability and genetic advance of seventeen characters were studied to identify the yield contributing characters and their gene action. PCV was found higher in magnitude than GCV for all the observed characters. The highest GCV and PCV were observed for the character number of suckers per plant. The characters such as internode length and duration of male and female phases were found to be influenced by environmental factors as they indicate high PCV and low GCV. High heritability coupled with high genetic advance was observed in almost all characters except internode length, days from emergence to maturity of leaves, number of suckers per plant, days from emergence to maturity of inflorescence and duration of female and male phases. These traits are controlled byadditive gene action and are less influenced by the environment. Thus, these characters can be used for reliable phenotypic selection of high yielding and superior anthurium hybrids.
