The breeding clones are the breeding objects selected after the first selection stage and vegetatively propagated to an amount appropriate for the needs of tests and experiments. This titer accompanies such genotypes until the variety is submitted to the registry. These are potentially future varieties.

The clones tested in the experimental conditions of Niwa are directed to the farms specializing in the cultivation of berry species both in Poland and abroad. Basing on the opinion of the growers, the breeder will decide whether they are the varieties or the next step in biological progress.
