Genetic variability of fenugreek (Trigonella foenum-graecum L.) accessions from agroecological and morphoagronomic traits, Ethiopia

Abstract

To develop crops through selection or hybridization, evidence of accession variability is required. The purpose of this study was to collect information on the variability of Trigonella foenum-graecum L. accessions based on agroecological and morpho-agronomic traits. Data on 11 quantitative characteristics of 160 accessions were collected. The analysis of variance results showed that there were significant differences between accessions for all traits. The first five principal components accounted for 65.9% of the total variation due to the number of seeds per pod, number of pods per plant and number of primary, secondary branches, seed yield (kg), with the first and second principal component accounting for approximately 17.9% and 15.2%, respectively. The Euclidean distance between genotypes ranged from 0.07 to 10.6, and the dendrogram created using the Unweighted Pair Group Method with Arithmetic Means (UPGMA) classified genotypes into two major clusters, indicating a higher possibility of developing varieties through direct selection or genotype crossing.
