The thirty-five diverse genotypes of finger millet including three checks viz., PRM-1, PRM-2 and VL-149 for seed quality parameters at seed testing laboratory of the department of seed science and technology, College of Forestry, Ranichauri Campus, V. C. S. G. Uttarakhand University of Horticulture and Forestry. The data on 14 quantitative traits viz., first count, standard germination, root length, shoot length, seedling length, seedling fresh weight, seedling dry weight, relative growth index, vigour index-I and vigour index-II were collected randomly from 10 seedlings form each genotypes. Genotype IC-308884 was highest for seedling length, vigour index-I and vigour index-II. Genotype IC-354383 was observed maximum germination percentage and relative growth index. Analysis of variance revealed highly significant among the germplasm for all the characters. Correlation studies revealed that all the traits of seed quality were associated with each other in terms of vigour. Seedling vigour-II exhibited very strong and positive correlation with seedling dry weight, seedling fresh weight and seedling vigour index-I while seedling vigour index-I showed highly significant and positive correlation with seedling length, root length, shoot length and standard germination. It is manifest that before assessment of seedling vigour, standard germination and seedling dry weight of the seed lots in any genotype could be used to envisage the yield potentiality of that genotype in open field conditions. | Correlation studies on seed quality traits in diverse genotypes of finger millet (Eleusine coracana (L.)
