A mini collection comprising 32 sainfoin genotypes was cultivated using a randomized complete block design with four replicates. Various parameters were recorded, including the number of plants per area (NPA), total dry yield (TDY), thousand seed weight (TSW), number of main stems (NMS), petiole length (PL), length of inflorescence (LI), number of leaflets per leaf (NLL), leaves per main stem (LMS), number of leaves per stem (NLS), stem dry weight (SDW), leaf dry weight (LDW), inflorescence dry weight (IDW), and number of florets per inflorescence (NFI). The first and second components of the biplot accounted for 88% of the variability in the dataset, with 70% attributed to the first component and 18% to the second. A pentagon was identified, featuring two distinct sections with genotypes 16 and 25, as well as genotype 14, serving as vertex entries. Notably, genotype 14 (Azna) excelled in three traits: NLL, LMS, and NLS. Additionally, vertex genotypes 16 and 25 demonstrated superior performance in other measured traits, including economically significant traits such as total dry yield. In accordance with the ideal entry, genotypes 13, 14, and 19, along with genotypes 16 and 25, exhibited greater favorability compared to other sainfoin genotypes regarding variability in the measured traits. Based on the ideal tester, total dry yield, number of leaves per stem, and number of florets per inflorescence were identified as key factors for assessing variation among genotypes. An examination of genotypes based on total dry yield indicated that genotypes 16 and 25, followed by genotypes 14 and 16, were the most desirable.
