N2 - This study was conducted in 2019‒2020 to morphologically characterize and cluster 26 germplasm entries of Bouffordia dichotoma, the native legume collected in eastern Amhara (Ethiopia) for eventual selection of promising lines as forage crops. The IBPGR descriptors list were used for characterization of the entries and data were analyzed using R software. Cluster analysis was conducted to understand the genetic diversity within the collection and to group similar entries. The experimental design consisted of completely randomized blocks with three replications for one year. The resulting dendrogram showed 3 distinct groups of entries: Group 1 with 12 entries; Group 2 with 6 entries; and Group 3 with 8 entries. Group 1 was significantly different (P<0.05) from Groups 2 and 3 in terms of days to first flower, terminal leaflet length, terminal leaflet petiole length, length of inflorescence and plant height, as well as emergence, establishment, vigor, flowering and maturity. Leaf color of Groups 1 and 2 was light green while that of Group 3 was green. While most entries had semi-erect growth habit, those in Group 3 were prostrate or trailing. Three distinct types of seed coat colors were observed with Group 1 including dark brown, light brown and yellow, while Groups 2 and 3 were yellow only.
