In order to evaluate genetic diversity of Iranian indigenous Fenugreek populations on the basis of morphological traits, thirteen populations were collected from different regions of Iran and the experiment was conducted based on a completely randomized design with three replications. Results revealed that all populations exhibited significant differences for majority of studied traits. Yield of landraces varied between 5.29 to 27.87gr of fresh weight. The minimum and maximum fresh weights were recorded in Marand and Marvdasht landraces, respectively. Also, landraces bloomed 46 to 79 days after sowing. Thousand kernel weight was variable from 8.60gr (Ardestani) to 29.80gr (Marvdasht). Correlation coefficients showed significant positive correlation of leaf area and fresh weight. Also, a significantly positive correlation was observed between height at harvest time with fresh weight and number of stems with number of flowers, and number of pods with number of seeds per pod. In this study, factor analysis dropped features into six main and independent groups. Factors with eigenvalues higher than one were justified 80.47 percent of total variance. Cluster analysis divided all populations into three main groups, in which, there were three, two and eight landraces, respectively. Generally, the results showed that Iranian Fenugreek landraces have a high genetic diversity in regard to the studied traits.
