Plant genetic resources are in the base of creating new adaptive varieties. Grain quality of 53 Bulgarian rye ac-cessions from the collection of the National Genbank has been evaluated. In two years the following traits were de-termined: 1000 kernel weight, test weight, crude protein, lysine+histidine, lysine+histidine in protein, crude fats, cel-lulose and ash content. The genetic distinctiveness was performed by a hierarchical cluster analysis considering the complex effect of the examined parameters. The 5 clusters in the dendrogram showed the considerable genetic dis-tinction among the evaluated rye accessions. Some of them have high protein content (15 %), lysine + histidine (1.2%), large grain, so they are valuable genetic material to be included in the effective breeding programs for high quality.
