Abstract

Twenty eight genotypes of gladiolus were planted for morphological variation and evaluation during 2005–08 in a completely randomized block design with 3 replications. The mean performance (3 years) of gladiolus data were highly significant for all the twelve growth, flowering and corms traits studied indicating the presence of variability. The genotypes were grouped into 8 clusters. Among the 8 clusters, cluster VIII was largest with 12 genotypes, followed by cluster I having 4 genotypes. The remaining cluster had 2 genotypes each. The maximum intra-cluster distance was exhibited by genotypes of cluster VIII, while the lowest by the genotypes of cluster II. The intercluster distance was highest between the cluster VI and VIII and lowest between cluster I and VI, and II and V. The different clusters have higher mean values for different traits, the genotypes ‘Anjali’from cluster I, ‘Dhanvantari’ and ‘Her Majesty’ from cluster VIII, ‘American Beauty’ from cluster III and ‘Sylvia’ from cluster VI deserve to be considered as potent parents for further improvement programme.
