Comparison of Twenty Selected Fenugreek Genotypes Grown under Irrigated and Dryland Conditions: Morphology, Yield, Quality Properties and Antioxidant Activities

In this study, 18 fenugreek genotypes and two cultivars were cultivated under irrigated and dryland conditions to determine the morphological, yield, quality, and bioactive properties. The morphological and seed yield values showed differences among the fenugreek genotypes and cultivars. The PI 286532 and PI 639185 genotypes for total alkaloid content and the PI 426973 and PI 572538 genotypes for trigonelline content were prominent under both irrigated and dryland conditions. The PI 215615 and PI 286532 genotypes were found to be rich in fixed oil contents under two growing conditions, while all fenugreek genotypes had high linoleic contents. The PI 568215 and PI 251640 genotypes and the g & uuml;rarslan cultivar had the highest antioxidant activity compared with the other genotypes. The PI 215615 and PI 302448 genotypes and the g & uuml;rarslan cultivar were found to be superior with respect to phenolic and flavonoid contents. Generally, the cluster analysis clustered the genotypes into two main groups and two sub-groups. Group B included more than 66% of the genotypes and cultivars. The biplot analysis accounted for over 53% of total variations. As a result of this study, most of the genotypes were found to be high in the examined properties, and these genotypes were good sources of natural components with potential applications in the food and pharmaceutical industries.
