Interspecific crosses of impatiens produce sterile hybrids. Amphidiploids bridge the transfer of genes from one species to a relative species. The experiment was conducted at the Experimental Station of the Indonesian Ornamental Crops Research Institute from January 2021–July 2022. The study was carried out to estimate the variability parameters for quantitative and qualitative characters and the similarity of the parents and their progenies. A Randomized Complete Block Design was used with 15 amphidiploid genotypes as the treatment. The genotypic and phenotypic variations were calculated using Analysis of Variance and expressed as genotypic and phenotypic variances and broad sense heritability estimate. The qualitative characters were analyzed as the degree of similarity for pairs of clones and their parents, cluster analysis of the morphological data, and matrix coefficient analysis. Results showed that the genotypic coefficient of variance ranged from 0.56% (eye zone width) to 68.64 % (flower width). The phenotypic coefficient of variation also had a similar trend as the genotypic coefficient of variation indicating that these characters are less influenced by the environment. The heritability varied from 17.05 (leaf width) to 99.35% (flower width). The level of similarity between genotypes based on the color of the flower, leaf, pedicel, spur, and stem was 14% suggesting differences in the genotypes. The results of this study imply that the following generation of crosses between amphidiploid genotypes with large variations followed by high heritability can turn out varied offspring and effective selection within the early generations.
