Description

The object of research - varieties and lines of winter oilseed rape. The purpose of research: to evaluate sort of collection of samples and the newly created source material of winter rape, to get breeding material and on its basis to create high-yield varieties of oil type and synthesize valuable components to create high heterosis hybrids. Research Methods: field (phenological observations), laboratory and measurement and weight (structural analysis of collection and hybrid material, accounting productivity, determination of the chemical composition of seeds), mathematical-statistical (correlation and regression and dispersion analysis, calculation the parameters of adaptability, degree of phenological dominance, true heterosis, combining ability). Established that stable feature is the height of plant, V10,1%. Considerable variability inherent attributes "number of pods from a plant" (V = 31,8%), "the number of seeds from a plant" (32.0%), and the "weight of seeds per plant" (33.2%). Marked a strong positive correlation between individual productivity and the number of seed pods per plant (r = 0,93 ± 0,06) and with a mass of 1000 seeds (r = 0,79 ± 0,13). Are allocated sort samples of 9 with a high ecological plasticity and 4 sort samples with high stability yield seeds. Was held hybridization for 130 combinations, resulting in fruits (pods) formed in 104 combinations whose seeds will be sown to study next year. The high total matching capacity on the basis of the weight of seed plants were characterized by 4 sort samples of Black giant _, Anna and Hypanis, low - Rohan, Visbi and Belana. High values of constants a specific combining ability was found in the object of research - varieties and lines of winter oilseed rape. The purpose of research: to assess the collection of samples and grades the newly created source material of winter rape, to get breeding material and on its basis to create high-yield varieties of oil type and synthesize valuable components to create high heterosis hybrids.

The high total matching capacity on the basis of the weight of plant seed _ were characterized sort samples the Black giant _, Anna and Hypanis, low - Rohan, Visbi and Belana. High values of constants a specific combining ability of hybrid populations found: Rohan / Belana, Anna / Rohan, Hypanis / Belana, of Black giant / Anna Hypanis / Visbi. The estimation in the number of 35 hybrid combinations with the participation CMS identified forms. All of them showed fixing sterility. The level of heterosis amounted 10-35%. In the competitive nursery were highlighted 4 numbers that by the yield of seed exceeded the standard for 0.4-0.8 t / ha and were characterized by low content of erucic acid - 0-0,3% and glucosinolates - 5-15 mmol / g. Created and transferred to the state variety trials sort of winter rape Monopolist. Application number 15040026 from 5 March 2015.
