The purpose of research: to assess the source material for spring rape ecological parameters ductility and stability of quantitative traits productivity, create and determine effects of dominance hybrids of the first generation to get promising breeding material to create on its basis high-grade oil type. Research Methods: Field (phenological observations), laboratory and measurement and weight (structural analysis of collection and hybrid material, accounting productivity, determination of the chemical seed composition), mathematical-statistical (correlation and regression and analysis of variance calculation parameters of adaptability, degree of phenological dominance, true heterosis, combining ability). Most stable sign of spring rape is height of plant (V = 11,0%). The mass of seeds from a plant was the most volatile in 2015, the driest year when the coefficient of variation was 32.4% and the average for the five years 30.5%. The greatest effect of general adaptive capacity _ have sort samples of Aira (vi = 2,56), Antei (vi = 2,0) and Sirius (vi = 1,1). Were noted high value of varians of a specific adaptive capacity have appeared in sort sample Sirius (?2SAZi = 15.16), Aira (?2SAZi = 13.77), Antei (?2SAZi = 13.03) and Ataman (?2SAZi = 12.47). The largest relative stability of genotypes were characterized varietal samples Ataman (Sg = 22,2%) and Sirius (SGI = 21.62%), the lowest grade Hunter (SGI = 17.47%). Are allocated best genotypes that combine high performance with a stable level of harvest samples revealed varietal Aira (STSH = 9.95), Antei (STSH = 9.65) and Hunter (STSH = 8.51). In the selected group got two genotypes (Aira and Antaeus) with a high overall adaptive capacity. This indicates that they can be extremely productive with high resistance to environmental conditions of varietal sample that have been studied. In the competitive strain testingare highlighted four rooms, which are on 0,08-0,40 t / ha higher than standard, the contents of oil allocated numbers are high (44,0-45,5%). Created and transferred to the state variety trials sort of spring rape Success.
