Object of research - analytical selection of lettuce seed. Subject of investigation - sortoobraztsov collection and breeding material lettuce seeds (177 samples). The purpose of research - to create lines and varieties of salad puff and capitate with a set of useful traits productively, to study the effect of growth regulators on seed productivity of varieties of lettuce seeds, explore after-mutagenic factors in expanding the range of selection-genotypic variability of forms salad. For chemical, morphological and organoleptic characteristics identify the best examples of salad for eating fresh. Methods - hybridization and individual and mass selection. In nursery inbred lines studied 56 samples of lettuce foreign and domestic origin, useful and productive characteristics (yield) distinguished 10 sortoobraztsov - at yield 8,1-9,0 t / ha. On the content of ascorbic acid color samples: Local 12 - 31.18 mg / 100 g, VDB - 33,78 mg / 100 g vs. 24.10 mg / 100 g standard, with high content of dry matter allocated Designs: Local 12 - 10 , 36% and Red credo - 10.41% against 9.65% in the standard. In nursery mutant forms M4-M5 evaluated 84 samples. Highlight of 14 samples stebluvannya extended period of 6 days. This nursery selected 10 best designs. All mutant forms of the yield higher than the control plants, the largest yield of leaf mass marked four samples: Snowflake (6) K-7121, gold layer (15) K-7170, Godard (18) K-7214, the princes K-7219, the yield of which varying from 8.0 to 8.7 t / ha. For dry matter content (10,29-11,31%) allocated like Godard (3) i.d.3 K-7094 and raspberry layer (3) i.d.1 K-7098 at 9.64% in the standard. The content of ascorbic acid ranged 18,91-36,87 mg / 100 g total sugar 0,95-1,45%. In breeding nursery F6-14 maximum yield for color samples: K-7292 F10 (Significant 495/745 x) and K-7295 i10 (Sarada Sans). These samples will be used to create lines. A variety of lettuce seeds puff Krutyanskyy, green mass yield of 9.5 t / ha, which is 3.8 t / ha, or 67% more than standard - grade gold layer. Drought 7 points (ustandartu 5 points). Dry matter content 9.54% (by 16.3% more than standard), total sugar 1.23% (by 66.2% more than standard), 27.9 mg of ascorbic acid / 100 g (16% from standard). Economic efficiency 21 thousand. UAH. / Ha. A variety of salad puff Patriot green mass yield 9.8 t / ha, 3.5 t / ha or 54.3% more than standard (grade Snowflake), drought 7 points (in standard 5 points), dry matter content 5.33% (6.2% in the standard), total sugar 0.75% (7% more than the standard), ascorbic acid 26.12 mg / 100 g (25.5% more than standard). Economic efficiency of 23.5 thousand. UAH. / Ha. A variety of salad puff Major green mass yield of 9.3 t / ha, 2.9 t / ha or 45.7% more than standard (grade Snowflake), drought 7 points (in standard 5 points), dry matter content 6.42% (3.5% more than the standard), 0.8% total sugar (23.1% more than standard), ascorbic acid 35.98 mg / 100 g (76.5% more than the standard ). Economic Efe-executor's 23.5 thousand. UAH. / Ha. A line lettuce seeds puff Ellan, green mass yield of 6.8 t / ha, which is 1.1 t / ha or 19.3% more than standard. Drought 7 points (ustandartu 5 points). Dry matter content 10.14% (by 23.6% more than standard), 1.23% total sugar (by 51.3% more than standard), 27.9 mg of ascorbic acid / 100 g (9.6% more than the standard). Economic efficiency 20 thousand. UAH. / Ha. Developed and submitted application number 2015 07557 for a patent for utility model "Method of obtaining new varieties of lettuce seeds puff variety," which features the fact that in the invention the task as more fully realize the potential of selective use of source material lettuce seed obtained by induced mutagenesis , including through the pre-treatment of seeds original forms of action of the physical mutagen, such as ?-irradiation of seeds. Using the method gives a new form, with up to 47% of the original sample distinctive morphological identification signs. Developed and submitted application number 2015 07903 for a patent for utility model "Method of improving the productivity of plants lettuce seed seed variety puff" through the use of composite preparations for pre-treatment of seeds that will improve the reproductive performance of seed plants salad at 24-28% Increase their resistance to early stebluvannya and provide high quality crop grown seed of high reproductions. Proven effectiveness presowing seed layer raspberry varieties of lettuce growth regulator D1, which provided seed yield increase of 22% to control. A reproduction of the original three varieties of lettuce: Gold layer (received basic seeds 5 kg), raspberry layer (5.7 kg) and Snowflake (17 kg), Olzhych (2 kg) Dyvohray (4 kg), Godard (6 kg).
