Results researches showed possibility application for extraction water solutions containing hydrogen peroxide, hydroxide and sodium bisulfite in conditions high-temperature influence within 2 hours with technical suitable production cardboard packaging materials. For purification cellulose, it was out additional processing by solution...

In 2024, 6 varieties of the Tomsk school breeding were tested at RGAU MSHA field experimental station. conditions year for cultivation flax proved to be optimal. Among all varieties, Tomich variety was distinguished by highest fiber yield (36.5%). terms seed productivity, 18 leader (82.5 pieces per plant), however, same showed lowest safety harvesting (420 plants from 1 plot). The Krepkov Memory had technical length (71.28 cm).

Effective work with seed material contributes to an increase in germination and sustainable development of agricultural plants. In this study, experiments were conducted on the pre-sowing treatment flax seeds a formulation containing activator growth processes – hydrogen peroxide polymer natural origin inulin, which helps reduce mucus secretion during semi-dry treatment. The experimental results obtained confirm effectiveness proposed formulation, plants facilitates procedure for performing...

In 2022 and 2023, at the field experimental station of Russian State Agricultural Academy named after K.A. Timiryazev, we evaluated some varieties oil flax for adaptability to climatic conditions central region Non-Chernozem zone Federation. During study, yield, elements crop structure, safety plants harvest, as well content oil, protein, fiber in seeds were evaluated. addition, possibility dual usage samples was too. According results coefficients variation signs calculated. The highest...

С целью создания сортов зернокормового направления в течение десяти лет проводили комплексную оценку 80 линий зернового сорго, 55 сахарного 70 суданской травы и 15 чумизы. В результате испытания новых сорго по комплексу биологических хозяйственно-ценных признаков выделены селекционные линии Л-211, Л-226 Л-355, которые среднем за пять превышали сорт-стандарт изучаемым признакам. Данные планируется передать на Государственное сортоиспытание. По результатам изучения селекционного материала...

Расширение площадей под посев сахарного сорго в Нижнем Поволжье сдерживается отсутствием сортов и гибридов, хорошо адаптированных к условиям региона. С целью изучения исходного материала для создания высокопродуктивных конкурентоспособных течение трёх лет проводили комплексную оценку 85 селекционных линий сорго. В качестве стандарта использовали районированный сорт Волжское 51.В результате проведенных исследований установили, что селекционные линии Л-16, Л-25 Л-42 можно выделить как...

For the arid zone of Lower Volga region, grain sorghum is an important forage crop. The paper presents results a comparative assessment yield and biomass breeding lines in nursery preliminary variety testing. volume for testing was 117 lines. most productive were sorghum, which reached 3.95 t / ha (line PSI-17 EV-56); 4.10 EV-113); 4.15 EV-55); 4.50 EV-92) with 3.75 standard Volzhskoe 4. As result scientific research, promising identified: EV-56 EV-92, recommended to be submitted competitive...

The article characterizes the advantages of sudangrass, presents its comparative assessment, and gives recommendations for cultivation a new variety Evgeniya seeds. Implementation program development forage production in Russia other countries implies not only creation varieties but also promotion their introduction. This study aims to test sudangrass refine techniques obtaining high-quality seeds Volga region. For period 2 years, we studied promising variety, lines that were obtained during...

It is given the initial material for selection of grain sorghum and further production testing prospective lines in Volga region. During 2 years, we studied 25 perspective breeding sorghum. As a result conducted scientific research best line grainsorghum MeV-1/16 conditions lower region which has exceeded sort-standard Perspectivniy 1 on complex economic-valuable signs. The Mev 1/16 passed to state variety testing. Production tests showed that obtain maximum yield high-seed seeds it...

A comparative assessment of spring wheat varieties was carried out in the collection nursery. Under conditions Non-Black Earth Zone Russian Federation, that are promising for breeding soft were identified.

In a competitive variety trial, promising selection lines of sugar sorghum were studied in the Lower Volga region. Based on set signs, best identified, which are recommended for transfer to State Variety Testing. Breeding lines, distinguished by high values commercially valuable traits, can be used planned crosses create highly productive varieties and hybrids sorghum.

With the aim of introducing a new variety Sudanese grass, Evgenia, into agricultural production in Lower Volga region, they conducted tests. Clarified methods cultivating varieties for seeds. As result research, it was found that Evgenia characterized by high values economically valuable traits. To obtain high-quality seeds, is recommended to be sown with row spacing 30 cm and seeding rate 0.6-0.7 million pcs. viable seeds per hectare.

Obtaining homozygous lines plays an important role in the creation of highly productive maize hybrids. However, standard method for obtaining such is extremely laborious and time-consuming to implement. The article discusses study a new accelerated creating lines.
