Purpose. Conducting economic evaluations of late varie­ties of white cabbage of various sort types bred by Kyiv experimental station of the Institute of Vegetables and Melons NAAS of Ukraine (IVM). Methods. Field, laboratory, statistical. Results. Experimental studies included phenological observations of plants growth and development, biometric measurements of vegetative and edible parts of plants, determination of biochemical сomposition of heads, records of yield and storability of late varieties of white cabbage of such sort types as Amager and Langedijska winter. Varieties with the highest yield, best biochemical composition and excellent storability of cabbage heads during four and six month periods were identified. Conclusions. Among the cabbage samples of Amager sort types, late variety Vasylyna was characterized by the highest yields. Olga variety provided the significant increase in productivity. Violanta variety had the highest yield within the sort type Langedijska (Langendijker) winter. Knyagynіa variety far exceed indices of standard Langendijker detsema. Late varieties of the first sort type produced the highest yield, the second ones demonstrated better biochemical composition and excellent storability of cabbage heads during four and six month period.

Purpose. To conduct a comprehensive agrobiological assessment of broccoli hybrids Brassica oleracea L. convar. botrytis (L.) Alef. var. сymosa Duch. in terms of the key agronomic traits under the conditions of the Western Forest-Steppe of Ukraine. Methods. The object of the study was the following foreign broccoli hybrids: ‘Lucky F1’ (reference), ‘Batavia F1’, ‘Belstar F1’, ‘Monaco F1’, and ‘Rumba F1’. Phenological observations, biometric measurements, and records were conducted in accordance with the Methodology of Experiments in Vegetable and Melons (2001). Results. On ave­rage over the years of research, the highest yield was obtained from hybrids ‘Monaco F1’ (41.2 t/ha) and ‘Rumba F1’ (38.0 t/ha). A slightly lower yield was in ‘Belstar F1’ (32.3 t/ha) and ‘Batavia F1’ (29.6 t/ha). In general, all hybrids under investigation provided a significant yield increase (6.3–17.9 t/ha) compared to reference ‘Lucky F1’ (23.3 t/ha). The largest diameter of the main head was recorded in the hybrids ‘Rumba F1’ (19.7 cm), ‘Monaco F1’ (20.5 cm) and the smallest in ‘Lucky F1’ (14.3 cm). The weight of the main head of all hybrids was significantly higher than that of reference (295 g): ‘Batavia F1’ 451 g, ‘Belstar F1’ 477 g, ‘Rumba F1’ 514 g, and ‘Monaco F1’ 542 g. The weight of the side heads of the broccoli ranged from 328 g (‘Lucky F1’) to 807 g (‘Monaco F1’). The highest biochemical indicators of commodity product were provided by hybrids ‘Rumba F1’ and ‘Monaco F1’: the total dry matter content was 11.3 and 11.6%, soluble solids 6.4 and 6.7%, sugars 3.5 and 3.8%, and vitamin C 89.3 and 98.7 mg/100 g, respectively. Conclusions. Under the conditions of the Western Forest-Steppe of Ukraine, it is recommended to grow new foreign broccoli hybrids ‘Rumba F1’ and ‘Monaco F1’, which ensure high yield and quali­ty of commodity product. According to the results of the agrobiological assessment, a typical model of broccoli variety is proposed, which may serve as a project for the development of the evaluation form for ability indicators of Brassica oleracea L. convar. botrytis (L.) Alef. var. сymosa Duch. for distribution inUkraine.

Цель. Провести комплексную агробиологическую оценку гибридов капусты брокколи Brassica oleracea L. convar. botrytis (L.) Alef. var. сymosa Duch. по основным хозяйственно-ценным показателям в условиях Западной Лесостепи Украины.Методы. Объектом исследования были гибриды капусты брокколи иностранной селекции: ‘Lucky F1’ (контроль), ‘Batavia F1’, ‘Belstar F1’, ‘Monaco F1’ и ‘Rumba F1’. Фенологические наблюдения, биометрические измерения и учеты проводили в соответствии с Методикой исследовательской дела в овощеводстве и бахчеводства (2001). Результаты. В среднем за годы исследований наивысшую товарную урожайность головок формировали гибриды ‘Monaco F1’ (41,2 т/га) и ‘Rumba F1’ (38,0 т/га). Нес­колько ниже она была в ‘Belstar F1’ и ‘Batavia F1’ – 32,3 и 29,6 т/га соответственно. В общем же все исследуемые гибриды обеспечили существенный прирост урожайнос­ти (6,3–17,9 т/га) по сравнению с контрольным вариантом (‘Lucky F1’ – 23,3 т/га). Наибольший диаметр центральной головки зафиксирован у гибридов ‘Rumba F1’ и ‘Monaco F1’ – 19,7 и 20,5 см, наименьший у ‘Lucky F1’ – 14,3 см. Масса центральной головки у всех гибридов была значительно выше показателя контроля (295 г): ‘Batavia F1’ – 451 г, ‘Belstar F1’ – 477, ‘Rumba F1’ – 514, ‘Monaco F1’ – 542 г. Масса боковых головок в зависимости от гибрида колебалась от 328 г (‘Lucky F1’) до 807 г (‘Monaco F1’). Самые высокие биохимические показатели товарной продукции обеспечили гибриды ‘Rumba F1’ и ‘Monaco F1’: содержание общего сухого вещества составило 11,3 и 11,6%, растворимых сухих веществ – 6,4 и 6,7%, сахаров – 3,5 и 3,8% и витамина С – 89,3 и 98,7 мг/100 г соответственно. Выводы. В условиях Западной Лесостепи Украины рекомендуется выращивать новые гибриды капусты брокколи иностранной селекции ‘Rumba F1’ и ‘Monaco F1’, которые обеспечивают формирование высоких показателей как урожайности, так и качества товарной продукции. По результатам агробиологической оценки предложено типичную модель сорта капусты брокколи, которая может служить проектом для разработки соответствующих бланков показателей пригодности сортов Brassica oleracea L. convar. botrytis (L.) Alef. var. сymosa Duch. для распространения на территории Украины. | Purpose. To conduct a comprehensive agrobiological assessment of broccoli hybrids Brassica oleracea L. convar. botrytis (L.)

Об’єктом дослідження були гібриди капусти броколі іноземної селекції: ‘Lucky F1’ (контроль), ‘Batavia F1’, ‘Belstar F1’, ‘Monaco F1’ та ‘Rumba F1’. Фенологічні спостереження, біометричні вимірювання та обліки проводили відповідно до Методики дослідної справи в овочівництві та баштанництві (2001).Результати. У середньому за роки досліджень найвищу товарну врожайність головок формували гібриди ‘Monaco F1’ (41,2 т/га) і ‘Rumba F1’ (38,0 т/га). Дещо нижчою вона була в ‘Belstar F1’та ‘Batavia F1’ – 32,3 та 29,6 т/га відповідно. Загалом усі досліджувані гібриди забезпечили істотний приріст урожайності (6,3–17,9 т/га) порівняно з контрольним варіантом (‘Lucky F1’ – 23,3 т/га). Найбільший діаметр центральної головки зафіксовано в гібридів ‘Rumba F1’ та ‘Monaco F1’ – 19,7 і 20,5 см, найменший – у ‘Lucky F1’ – 14,3 см. Маса центральної головки в усіх гібридів була значно вищою за показник контролю (295 г): ‘Batavia F1’ – 451 г, ‘Belstar F1’ – 477, ‘Rumba F1’ – 514, ‘Monaco F1’ – 542 г. Маса бокових головок капусти броколі залежно від гібрида коливалася від 328 г (‘Lucky F1’) до 807 г (‘Monaco F1’). Найвищі біохімічні показники товарної продукції забезпечили гібриди броколі ‘Rumba F1’та ‘Monaco F1’: вміст загальної сухої речовини становив 11,3 і 11,6%, розчинних сухих речовин – 6,4 і 6,7%, цукрів – 3,5 і 3,8% і вітаміну С – 89,3 та 98,7 мг/100 г відповідно.Висновки. В умовах Західного Лісостепу України рекомендується вирощувати нові гібриди капусти броколі іноземної селекції ‘Rumba F1’ та ‘Monaco F1’, які забезпечують формування високих показників як урожайності, так і якості товарної продукції. За результатами агробіологічного оцінювання запропоновано типову модель сорту капусти броколі, яка може слугувати проектом для розроблення відповідних бланків показників придатності сортів Brassica oleracea L. convar. botrytis (L.)
