ENVIRONMENTAL TESTS OF CRAMBE АBYSSINICA UNDER THE CONDITIONS OF THE MIDDLE VOLGA REGION
The article deals with the results of testing the varieties of crambe abyssinica of domestic and foreign breeding. Their productivity was studied in the conditions of the Middle Volga region, which in the average for three years varied in the range 2.58-3.05 t/ha, oil content reached high values of 47.5-49.4 %. The estimation of the compensatory effects on the elements of the structure of the crop by the criteria of adaptation of different varieties to individual temperature factors in different periods of ontogeny. These indicators quantify the reactions of crambe varieties to environmental factors during the vegetative period, adaptability and ecological plasticity to the growing conditions. According to the indicators varieties Polet (bi = 0,95; σdr2 = 0,08), Belenzian (bi = 0,98; σdr2 = 0,08) and Demetra (bi = 0,99; σdr2 = 0,07) were identified. They are more adapted to unfavorable conditions and adapted to the agro-climatic conditions of vegetation in the conditions of Penza region. There shown economic and biological characteristics of the new varieties of the of crambe abyssinica Demetra and Polet with a yield of up to 3.22 and 3.06 t / ha, respectively. The original producer of these varieties is Penza SRIA, they are included in the State Register of Selection Achievements and recommended for all regions of RF.
