The extent of genetic diversity plays an important role in varietal improvement programme of a particular crop. An experiment was conducted to study genetic divergence in 25 genotypes of cauliflower and data was recorded for 17 quantitative characters. On the basis of D2 statistics, the genotypes were grouped into three clusters. Based on inter and intra-cluster distances, maximum intra-cluster distance was observed in Cluster I, indicating that the genotypes included in this cluster were genetically diverse. Further, inter-cluster distances revealed maximum values between Clusters I and II, followed by Clusters I and III and, clusters II and III. On the basis of cluster means, Cluster I was observed to be important for earliness and yield characters suggesting the scope of improvement for these traits through the use of genotypes included in this cluster. On the other hand, for morphological and quality characters, Cluster II was observed to be important. Hence, genotypes from diverse clusters with high mean values for different characters present the best choice for further exploitation in cauliflower improvement programme.Keywords
