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 69 plants. On combinations the saturant crossing is conducted and seed are got. On 8 combinations (on marker signs) the hybrids are distinguished 70 plants. Estimating numbers translated on the ploid level of poliploid plants are preliminary (on morphological signs) distinguished with the signs of tetraploid set of chromosomes in an amount 15 things.
