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.
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
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.
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.
