The aim of the research is to identify species that are resistant to weather factors and stress and are able to grow under different environmental conditions. For this it is necessary to solve a number of objectives: to select species, to master the crossbreeding technique, conducting of crossbreeding, obtaining and growing of hybrid seeds.
