The study was carried out in the Central Highlands Region, Dhamar Governorate, Republic of Yemen, in nine different locations in mid-July 2020 in three districts which are Mayfa’a Ans, Otma and Al-Hadda, in each district, three locations were chosen for the purpose of studying the phenotypic and productive characteristics of tree varieties of lentil (1 local and two improved Dhamar -1- and Dhamar -2), each cultivar was planted with an area of 150 m² in each site and was relied on 16 descriptive and quantitative traits. The results showed that the cultivars were divided into two groups, the first group included the Dhamar  -1 variety, the second group included the local variety (Landraces) and Dhamar -2, the results of the cluster analysis indicate that the improved variety differed from the local variety  and Dhamar  -2 variety  in many characteristics and the degree of kinship reached 70%, which indicates the presence of genetic divergence between them, while the degree of kinship between the local variety (Landraces) and Dhamar -2 reached 78%, which indicates the presence of genetic closeness between them, and therefore it is possible to rely on the phenotypic characteristics to distinguish between the varieties, the study confirms the importance of expanding it by increasing the number of varieties in addition to the molecular study.

Key words: phenotypic characteristics, cluster analysis, genetic kinship and Lentil.
