The paper presents the results of evaluation of the collection large-seeded lentil cultivars using cluster analysis in the conditions of the Saratov region. The application of this method promotes the grouping of the studied genotypes according to the set of traits required by the breeder according to the criterion of the greatest similarity. The evaluation of the model popula-tion studied showed low variability (< 10%) in the following traits: stem length, content of protein, ash, fiber and NFE in seeds, i.e. the varieties dif-fered little from each other in the above traits. The following traits: sprout-ing-full flowering, sprouting-full ripening, height of lower bean attachment, 1000-seed weight, fat content in seeds were characterised by medium varia-bility (10-20 %), and other studied traits were characterised by high variabil-ity (> 20 %): number of beans per plant, number of seeds per plant, seed weight per plant, seed yield.
As a result of cluster analysis, samples with high values of economical-ly important traits were identified: protein content (k-2806, k-2981, k-2886, k-3086, k-3083, k-3059, 2511, k-3052, Oktava); yield (k-3035, k-2844, k-2867, k-2843, k-3061, k-2985, k-3054, k-2850, k-3033, k-3034, k-2945, Nadezhda), plant height and level of lower bean attachment (k-2776, k-3030, k-2920, k-2910, Delta, Danaya). They are recommended to use them in fur-ther breeding work when developing varieties with different breeding meth-ods.
