Abstract
A research work on genetic divergence, analysis was estimated in 75 genotypes of fenugreek (Trigonella foenum-graecum L.) grown in an Augmented Block Design during Rabi season of 2019-20 at Main Experiment Station of Department of Vegetable Science Acharya Narendra Deva University of Agriculture and Technology, Ayodhya. The objective of this study was to characterize morphological differences and yield related traits among 75 fenugreek accessions. Genetic diversity among 75 fenugreek genotypes (Trigonella foenum-graecum L.) was assessed. The estimation of genetic diversity among tested genotypes was highly significant, which got grouped into 8 clusters with cluster VI comprising maximum genotypes. Maximum intra-cluster distance (31.23) was observed in cluster V followed by cluster IV (15.51). Similarly maximum inter cluster distance was recorded between the cluster V and VIII (111.88) followed by cluster III and VIII (111.81) respectively. Although maximum cluster means for seed yield traits was recorded for cluster V and III respectively, suggesting a wide range of diversity for most of the economic traits that would enable breeder to identify the genotypes with suitable traits to be used in direct selection and also in improvement programme for broadening the genetic base. 75 accession showed distinguished variation in the dendrogram for all the studied parameters.
