The grain quality of accessions from the rye collection in the National GeneBank, Sadovo.

Plant genetic resources are in the base of creating new adaptive varieties. Grain quality of 53 Bulgarian rye accessions from the collection of the National Genbank has been evaluated. In two years the following traits were determined: 1000 kernel weight, test weight, crude protein, lysine+histidine, lysine+histidine in protein, crude fats, cellulose 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 distinction 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.
