Листовая капуста, объединяющая две группы разновидностей в составе вида капуста огородная (Brassica oleracea L.), имеет многоцелевое использование: в качестве ценного сочного корма для всех видов сельскохозяйственных животных и птицы, а также пищевое и декоративное. Широкое генетическое разнообразие культуры структурировано в 18 агроэкологических сортотипов. В последние годы культура в качестве кормовой незаслуженно забыта в России. Настоящая статья посвящена изучению хозяйственно ценных признаков 46 образцов листовой капусты из мировой коллекции генетических ресурсов ВИР им. Н. И. Вавилова при выращивании в Северо-Западном регионе РФ (г. Пушкин) в 2014–2020 годах. Установлены источники признаков продуктивности (массы растения, доли, высоты и диаметра стеблей, числа листьев, ветвистости): Schnitt Gelber Butter, Максилла, Lacta, Col Forrajera, местный сорт Черногории к-384 (урожайность 132–180 т/га при размещении 30 тыс. растений на 1 га). Выявлена устойчивость или высокая толерантность изученных сортообразцов листовой капусты к поражению болезнями (килой, пероноспорозом, альтернариозом, сосудистым бактериозом). Установлено, что к листогрызущим вредителям (капустной моли и капустной совке, а также к капустной мухе) устойчивы главным образом курчаволистные сорта различного происхождения и местные плосколистные сорта из Испании и Абхазии. Выделены источники высокого содержания аскорбиновой кислоты и пигментов (хлорофиллов, каротиноидов, антоцианов): главным образом местные и тёмноокрашенные сорта, включая сорт пальмовидной капусты с тёмно-зелёными листьями и гибрид листовой и брюссельской капусты с тёмно-фиолетовыми листьями. По комплексу ценных признаков выделены старый российский сорт Мозговая синяя сиверская, испанский местный сорт Berza alta, немецкий курчаволистный сорт Gruner halbhoher. Кормовая капуста заслуживает возвращения в рацион животных и, соответственно, расширения площадей её возделывания в РФ. Brassica oleracea L. convar. acephala (DC.) Alef. and B. oleracea L. convar. fruticosa (Metzg.) Alef. can be used as a valuable fresh forage for livestock and poultry, food or ornamental plants. High genetic diversity of these crops is represented by 18 genotypes adapted to various environments. Unfortunately, over the last years these plants were not used in livestock feeding. The report deals with economically important traits of 46 kale genotypes obtained from the N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The crop was cultivated in the north-west of Russia (Pushkin) in 2014–2020. Such genotypes as Schnitt Gelber Butter, “Maksilla”, Lacta, Col Forrajera, and k-384 had the best characteristics (plant mass, proportion, height and diameter of stems, leaf number and lateral development), leading to productivity of 132–180 t ha-1 when seeding 30 thousand plants per 1 ha). Genotypes showed high resistance to various diseases (clubroot, mildew, Alternaria leaf spot, black rot). Curly kale as well as genotypes from Spain and Abkhazia had high tolerance to diamondback moth, cabbage moth, and cabbage fly. The sources of high content of ascorbic acid, chlorophylls, carotenoids, and anthocyanins were identified: mainly local dark-colored varieties. “Mozgovaya sinyaya siverskaya”, Berza alta, Gruner halbhoher had a number of economically important traits. Kale is recommended for livestock feeding, and therefore the area of its cultivation should be increased in Russia.

When we evaluated the nucleopolyhedrovirus of the diamondback moth, Plutella xylostella (L.) (PxMNPV), in small plots of collard, Brassica oleracea L., artificially infested with this insect, numbers of larvae were reduced in all tests. Further reductions were obtained with the addition of a fluorescent brightener (Blankophor P167®) in both tests in which it was included. Addition of an ultraviolet light protectant (photostabilized titanium dioxide) to PxMNPV also improved control, but only when the test was conducted in May and June. Titanium dioxide had no effect when the test was conducted in September. Addition of both materials together did not improve results compared with addition of Blankophor P167 alone. No virus treatment, however, was as effective as the insecticide spinosad.

DIVERSITY OF SUPRESSIVE LAND MICROFLORA IN CONTROL OF PALLDER DISEASE IN CUBES PLANT (BRASSICA OLERACEA L.)Cabbage (Brassica oleracea L.) was a vegetable crops cultivated in the highlands to meet the needs of the community vegetable. The main obstacle was the cultivation of cabbage root disease outbreak mace (clubroot), which until now have not found an effective control techniques. Clubroot disease caused by organisms that resemble fungi: Plasmodiophora brassicae Wor. which was the soil inhibitant and soil borne pathogen. Therefore, there must be a way to control environmentally friendly by using suppressive soil, find microbes antagonists related to the cabbage plant habitat in the soil. The results showed that the index of diversity both on suppressive and conducive soil of 1.2304 and 1.2811 respectively, and the index of dominance on the suppressive and conducive soil were 0.6677 and 0.6838.  Prevalence micoflora of the suppressive soil amounted to 44.22 % and 43.06 % conducive soil all dominated by Fusarium spp. Microbial antagonist as a potential control of P. brassicae was Trichoderma sp. Based on the analysis in the suppressive soil as much as 171 x 103 cfu /g soil, higher than on the conducive soil to 90 x 103 cfu /g soil.
