In order to identify diversity of maize inbred lines, a trial consisting of 15 inbred lines of maize were planted in Randomized Block Design (RBD) in three replication at AICRP Maize breeding field of Dr. Rajendra Prasad Central Agricultural University, Pusa during kharif-2016. The diversity was identified on the basis of morphological data like days to 50% tasseling, days to 50% silking, plant height, ear height, number of grains per row, thousand seed weight, tassel length, tassel branch number, cob length and cob girth. Descriptive statistics and cluster analysis were done with the help of MINITAB version18 statistical software and clustering was done by ward linkage method. The inbred lines were grouped into three major clusters A, B and C. Cluster B had taller plants with maximum ear height. The cluster C was characterized with shorter plants with minimum ear height. The inbred lines categorized into cluster C had early flowering, whereas cluster B had late flowering time. The inbred lines grouped into the cluster B were characterized by higher tassel length and tassel branch. Results indicated that amongst the tested inbred lines a wide range of morphological diversity were found. It could be utilized in future Maize breeding program to develop potential hybrids and synthetic varieties.
