In last 20 years in DAI – General Toshevo were created considerable number
of dry bean varieties, corresponding to varied market requirements regarding
technology of cultivation, grain massiveness, cooking duration and taste qualities.
Their introduction and protection of genetic purity was of great importance for the
breeding center. The presented investigation demonstrated the results of including
of cultivars Eliksir, Blyan and Ustrem into complete scheme of seed production.
The presented results showed different percentage of waste progenies depending on
climatic conditions and the stage of initial seed production. The most important for
progenies decline in initial stages were germination and lower seed yield. Diseases
attacks was also connected to individual waste progenies mainly for avoiding of
their further spreading.
