The present investigation comprising of 101 barley genotypes was conducted at Genetics and Plant Breeding, Banaras Hindu University, during rabi of 2016-17. Variability and diversity analysis was carried out based on data collected on 13 various quantitative traits. High Phenotypic coefficient of variation (PCV) and Genotypic coefficient of variation (GCV) was observed for grain yield plant, proline concentration and grain per ear. Medium PCV and low GCV values were displayed for days to heading. High heritability coupled with high genetic advance was observed for plant height, spike length, number of spikelets per spike, number of kernels per spike, kernel weight per spike, thousand kernel-weight and days to 50% flowering. These 101 barley genotypes were grouped into 12 clusters based on relative magnitude of the D2 values. The intra cluster distance was found minimum for cluster I and maximum distance in cluster VI while it was zero for cluster III, IV, V, VII, VIII, IX, X, XI and XII as these clusters consisted of only single genotype. The maximum inter-cluster distance was recorded between cluster VIII and cluster X. The cluster V had high mean value for flag leaf length, spike length with awn, spike length without awn and grains per ear. Cluster IV had high mean value for plant height, SPAD value; cluster III had high mean value for stomatal conductivity.
