Online published on 7 June, 2018. Abstract An investigation was carried out to study genetic diversity and associations between yield components and agronomical traits in 60 genotypes of fenugreek. Analysis of variance showed significant differences among cultivars for all the growth parameters studied. High genotypic and phenotypic coefficient of variance was recorded for seed yield followed by number of pods/plant and seed viogur-II. High heritability was also observed for seed yield (81.75%) and number of pods/plant (73.91%). Seed yield was significantly and positively correlated both at genotypic and phenotypic level to plant height, number of branches/plant, number of pods/plant, number of seeds/pod, test weight, germination and vigour. Highest positive direct effect on test weight followed by seed vigour-I, plant height and number of seeds/pod were also recorded. The information generated on these statistical parameters would be beneficial to identify the accessions having better yield potential which can be utilized in improvement of fenugreek.
