Description Field experiment was conducted for two consecutive years to evaluate snapdragon genotypes for genetic variability, heritability and genetic advance. Analysis of results revealed highest range of variation for number of leaves/plant. General mean was highest for number of leaves/plant and lowest for petiole length. Phenotypic and genotypic coefficient of variation was recorded maximum for number of secondary branches/plant and minimum for days taken to flowering. Genetic advance was observed maximum for number of leaves/plant and minimum for petiole length. High heritability with high genetic advance as per cent of mean was noticed for floret diameter. On the basis of D2 values, thirtyfive genotypes were grouped into five clusters. Maximum inter- cluster distance was observed between cluster III and IV, followed by II and III.
