Large genetic diversity exists in Lupinus albus L. expressed by its morphological and agronomical traits. The aim of this study was to assess the genetic diversity of ten white lupin accessions regarding components of productivity and biological traits. Two years trial was carried out on the experimental field of Institute of plant genetic resources during the period 2018-2019. The traits were evaluated using the International Lupinus albus descriptor; the degree of earliness - by Kuzmova, 2002. Based on agro-morphological traits the studied accessions were grouped into two clusters. The first cluster included only one accession. The second claster was divided into two sub-clusters. The first sub-cluster included three genotypes which differed significantly from the remaining ones by its tall plants, high first formed pods and a big number of grains per plant. The second sub-cluster included six accessions possessing medium-high to short stem and medium-large to large grains. The studied traits were combined into two main clusters. The largest Euclidean distance had between vegitation period and other studied traits. According to the degree of earliness, the lupen genotypes were clustered into three groups - ultra-early, early and late. The BGR 3086 accession was selected also as an ultra-early variety with 1.00 coefficient of earliness together with two other genotypes - selected to the early group with a coefficient of earliness 1.60. Genetically distant genotypes will be involved in the breeding programs for effective combining the important features into a new genotype.
