Abstract
Wide range of genetic diversity was observed among twenty three germplasm lines of ash gourd collected from different parts of U.P. and Uttarakhand. Genotypes PAG-50, Pant Petha-1, PAG-64, PAG- 12, PAG-14 and PAG-09 were high yielding lines while considering both the seasons summer and kharif 2006. Based on Mahalanobis’ D2 analysis all germplasm lines were grouped into 5 clusters. The clustering pattern indicated that geographical distribution need not necessarily be related to the genetic diversity. Cluster I was very large containing 14 genotypes (summer) and 10 genotypes (kharif) season. The commercially released cultivar Pant Petha-1 was grouped in cluster II along with other genotypes in both the seasons. The inter-cluster distance was found maximum between cluster III and cluster IV (summer) and cluster II and cluster V in (kharif) seasons. The genotypes in these clusters may possibly be utilized in hybrid breeding programme for successful exploitation of hybrid vigour in ash gourd.
