Aim: Millets play a key role in the food security of Central Himalayan Region. Evaluation of finger millet [Eleusine coracana (L) Gaertn] genetic diversity is yet lacking in this region. Hence, the present study was conducted with the aim to explore, collect and evaluate the genetic diversity of finger millet in order to identify trait specific germplasm for crop improvement.


Methodology: Exploration expeditions were conducted in the finger millet growing areas of Central Himalayan Region i.e., Uttarakhand State of India. A total of 314 accessions were collected from altitudinal range of 225 ? 2250 m asl. Collected germplasm was grown at one place and evaluated for various pheno-physiological traits.??


Results: Ample diversity was found in pheno-physiological traits viz., flag leaf length (17.91 ? 97.92 cm), fag leaf width (0.83 ? 1.23), flag leaf angle (19 - 530), peduncle length (9.02 ? 45.43 cm), plant height (71.71 ? 140.30 cm), days to 50% flowering (66.00 ? 98.00), days to 80% maturity (117.00 ? 147.00), days to harvesting (141 - 149), ear head length (4.16 ? 14.61 cm) and 1000 seed weight (1.01 ? 4.71 g). In addition, these accessions were evaluated for variability in total chlorophyll (1.02 ? 6.90 mg.g-1 fresh weight), carotenoids (0.87 ? 4.33 mg.g-1 fresh weight) content and lipid peroxidation (0.55 ? 7.42 n mol MDA formed. mg-1 protein. hr-1). Seeds of collected germplasm had wide variability in nutritional traits viz., carbohydrate (72.56 ? 79.22%), fat (1.31 ? 2.52%) and protein (5.66 ? 12.96%) content. Principal components responsible for variability were identified. ??


Interpretation: Central Himalayan Region has been found to have enormous diversity of finger millet. Collected germplasm had remarkable ability to withstand varying weather conditions and resistance to environmental/ abiotic stresses. Substantial diversity noticed in different traits might be utilized for crop improvement to develop nutritionally rich and abiotic/ biotic stress tolerant varieties.
