The purpose of the study: the study of promising numbers in the competitive and preliminary testing and propagation of seeds of promising varieties. The main results of the work. In the analysis of the descendants of the first generation by plant height, the highest heterosis by trait was observed in hybrids, where thematernal form was a tall parental component and depression where the lowest parent component used. The main results of the work. In breeding and hybrid nurseries in F1 the analysis of the collected samples on economically valuable features was carried out. In F2 - F6 selections were made on the following grounds - the number of seed boxes on the plant, plant height, weight of 1000 seeds and oil content in the seeds; According to the results of research in the control nursery in 2021, two samples №4 (Vodogray / Sunny) and №5 (Sympathetic / Blue-Orange) exceeded the South Night standard in terms of straw yield by 0.49-0.63 t / ha, in terms of yield seeds - by 0.16 - 0.75 t / ha and were characterized by a high oil content in the seeds - 41.0-43.0%, resistant to lodging and fusarium wilt. In the previous variety test of 11 numbers of the standard standard Southern Night (1.81 t / ha) on seed yield by 0.22-0.43 t / ha exceeded four selection numbers 4 (KR4-20), 5 (KR5-20) , 6 (KR1-19) and 10 (KR5-19) and were characterized by oil content in the range of 41-43.0%, resistance to lodging and fusarium wilt. Out of 7 numbers of the competitive variety test, the national standard variety Southern Night, in terms of seed yield, significantly exceeded only one number 2 (PSV2-20) by 0.28 t / ha. In terms of oil content, the majority of tested CSR samples were in the range of 41-43%, and in terms of oil collection - 0.67-0.77 t / ha, which exceeds the standard by 0.02-0.14 t / ha. Most specimens were resistant to lodging and disease. Product Description popup.authors Kondratiuk Viktor V. Kopatch Zoya I Pyvovar Tetiana M. popup.nrat_date 2022-03-09 Close
