Resumen:
The objective of this work was to evaluate 81 lentil cultivars using morphological traits and seed 8 characteristics using digital phenotyping. Caliber (C) and the color traits luminosity (L), color 9 coordinates a and b, and color index (CI) were measured and analyzed with appropriate software; also 10 yield (Y), plant height (PH) and days to flowering (DF) were measured. Highly significant differences 11 between cultivars was present for all traits and high heritability in board sense broad sense heritability 12 (H2B) for C (97%), CI (94%), a (93%) and L and b (83%) were found, indicating high genetic variability 13 for these traits. Digital phenotyping showed to be a powerful tool for germplasm characterization along 14 with field evaluation of agronomical traits. Principal Component Analysis and Cluster Analysis allows 15 de identification of differentiated groups of cultivars with similar characteristics, leading to a more 16 efficient use of the germplasm available as commercial cultivars or as parents in a breeding program. 17 Among these groups, group 1 had 32 cultivars with highest C and group 2 had 21 cultivars with higher 18 Y
