Abstract
The genetic diversity in 48 lupin (Lupinus albus (L.) accessions collected
from the Amhara region, Ethiopia, was assessed using seed storage protein
markers (SDS-PAGE). A total of 30 different protein bands with sizes ranging
from 11 to 100 kDa were detected. The average number of protein bands, the
percentage of polymorphism, and gene diversity in the accessions were 16.96,
20.35, and 0.072, respectively. Genetic diversity estimates showed that West
Gojam and Bahir Dar areas could be the most important sources for lupin
genetic resources. The pair-wise comparison of genetic distances (GDs) among
the accessions ranged from 0.011 to 0.378. The most distantly related
accessions were accession 6, collected from the West Gojam zone, and
accession 28 from the Bahir Dar area. Principal coordinate analysis (PCoA)
showed the absence of a distinct group, and most of the accessions were
intermixed. Population structure analysis revealed that the 48 lupin
accessions could be assigned to three clusters. Similar to PCoA, no defined
grouping based on geographic origin was observed. Accessions from different
geographic origins being grouped together could be attributed to a common
origin for the various accessions in the different zones, or it could be the
result of seed-mediated gene flow among different lupin growing areas of the
country.
