Aim of work: estimation and selection in the breeding nursery of the best weekend and hybrid forms on economic-valuable signs. Expansion of genetic variety is due to creation of new hybrid material. Research methods: the field, laboratory, instrumentation gravimetric. Basic results of research: new plant-breeding numbers are distinguished on a sign"long-termness of plants", namely: diploid are 10 numbers, tetraploid are 3 numbers. On combinations the saturant crossing is conducted and seed are got. At artificial frozing of hybrid combinations plants are distinguished with an increase firmness to the depressed temperatures in an amount . On combinations the saturant crossing is conducted and seed are got. In 4 combinations (on marker signs) hybrids in the amount of 16 plants according to vegetative and seed productivity are identified. Imbridization of 22 rooms.
