Abstract: The present investigation was conducted during Kharif, 2016 at Gaja Research Station, and Seed Testing at Department of Seed Science and Technology, V. C. S. G. Uttarakhand University of Horticulture and Forestry, College of Forestry, Ranichauri Campus with 200 accessions of finger millet including four checks viz., VL-352, GPU-28,PRM-1and PRM-2. Observations were recorded for field parameters, analysis seed quality parameters and diseases incidence. The characters studied morpho-metric traits were days to 50 per cent flowering, productivity tillers plant-1, peduncle length, number of fingers plant-1, finger length, plant height, ear length, days to maturity, seed yield plant-1,1000 seed weight. The incidence of diseases for leaf blast and severity of cercospora leaf spot were recorded. The seed quality parameters were recorded for first count, standard germination, root length, shoot length, seedling length, seedling fresh weight, seedling dry weight, vigour index-I and mean daily germination. The data was utilized for estimation of mean, range, genetic diversity, principal components, coefficients of variation, heritability and genetic advance, ,correlation coefficients. The genotype exhibiting high mean performance for grain yield along with high performance for some other yield components were IC-477722, IC-476745, IC-587978, IC- 477556, IC-476523 and IC-476958. High magnitude of phenotypic and genotypic coefficients of variation were noticed for finger length, finger per plant, days to 50 per cent flowering, and ear length, 1000 seed weight and peduncle length. High heritability coupled with high genetic advance was observed for, plant height, days to 50 per cent flowering, finger length, and 1000 seed weight. The 200 accessions of finger millet were grouped into 15 clusters irrespective of geographical diversity, indicating no parallelism between geographic and genetic diversity. The cluster pairs exhibiting very high inter-cluster distances were cluster VI and XV followed by cluster VI and XIV, cluster V and XV cluster V and XIV and cluster IV and XV would be fruitful for obtaining transgrassive segregants for developing high yielding and better quality finger millet varieties. The accessions IC-476959 was highest for standard germination seedling length and vigour index-I. High heritability coupled with high genetic advance was observed vigour index I in seed quality. Highly phenotypic and genotypic correlation coefficient was observed in seedling length. The genotypes minimum value was found in IC-`477323 IC-476039,IC-475257, IC-477373 IC- 477599 and IC-477156 showed lowest from incidence of leaf blast and IC-477431, IC-0476409,IC- 0477157,IC-476783,IC-476404 and IC-0477187 showed lowest value for severity of Cercospora leaf spot.
