A two-year study was conducted at Giza Research Station, Agricultural Research Center (ARC), Giza, Egypt during 2020/2021 and 2021/2022 seasons to evaluate the yield potential of twenty five lupine genotypes and identify their morphological traits compared with cultivar Giza 1. Twenty six genotypes (75 B 15.17, 75 B 9.15, P 20950, Family 2, Family 4, Family 11, Family 12, Local 12, Local 20, Line 6, Line 15, Line 21, X1/90/72, Sakolta, Qena, Edfo, Isna 1, Isna2, Isna 6, Isna 7, Qous 1, Qous 3, Qous 4, Qous 5, Belbais 9 and Giza 1) were distributed in a randomized complete blocks design in three replications. Sixteen morphological traits were described using UPOV (The International Union for the Protection of New Varieties of Plant) Guidelines. The morphological characterization indicated that the short or medium growth habits of genotypes at the flower bud stage were absent, and very tall genotypes at the green repining stage were not observed. Also, violet, pink, light yellow, and dark yellow flower wings, as well as late or very late maturing genotypes were absent. Moreover, stem anthocyanin coloration and the leaf green color at the flower bud stage, as well as the density of seed ornamentation were observed in all genotypes. The combined analysis of variance showed that lupine genotypes differed significantly for all the studied traits. Meanwhile, seasonal effects and their interactions were not significant for all the studied traits.
