Abstract
The article presents the study results of the tocopherols contents in the lines breeded by Yuriev Plant Production Institute, mutant lines with a modified spectrum and also fourth-generation inbred lines. The α-tocopherol predominance and a low β-, γ- and δ-tocopherols content in all lines of the genetics and sunflower breeding laboratory has been established. The maximum α-tocopherol content is 99.22 % of the total amount in the X135B line, which was one of the paternal components in breeding schemes. A high β-tocopherol content was found in the line X736B – 6.13% of the total amount. The X279B line has a high γ-tocopherol content, which was 3.59% of the total tocopherols amount. The line Х134В had increased δ-tocopherol content – 1,22% of the total amount. The results of mutant lines analyzes, which were used as a maternal component in breeding schemes of crosses, showed the presence of the entire tocopherols spectrum. The high β-tocopherol content was shown in lines Vk-L-4, Vk-L-7, Vk-L-8 – 57.21 %; 55.62; 46.81 % of total amount, respectively, high γ-tocopherol content – in lines Vk-L-1, Vk-L-2, that was 21.37 % and 13.00 % and δ-tocopherol – 68.75 % and 13.83 % of total amount, respectively. These research results make possible using these lines as sources of different tocopherols isomers increased content in order to create new sunflower forms with the desired tocopherol complex. The study of I4 on the composition of different tocopherols isoforms showed the presence of whole complex. Thus 12, 16, 17, 25, 29, 47 showed a high β-tocopherol content – 25.10%$ 42,01; 46,12; 43,03; 58,44 and 43,99 % of the total amount, respectively. The high γ-tocopherol content was tagged in 5 lines (7, 11, 12, 19, 38), which was 49.00%, 19.40; 11.72; 75.65 and 42.26% of the total amount respectively. One line (12) was also distinguished by the presence of the entire tocopherols spectrum: α-tocopherol content was 43,43%, β-tocopherol – 25,10%, γ-tocopherol – 11,72%, δ-tocopherol – 19.75% of the total amount.. The increased δ-tocopherol content was observed in lines 12 and 19 – 19.75 % and 10.02 % of total amount, respectively. The results of the studies indicate the possibility of using the obtained material in the sunflower breeding schemes to get new forms with an altered composition of tocopherols and also adapted for cultivation in the Eastern Forest-steppe zone conditions.
