Cauliflower is a valuable dietetic food product exceling other varieties of cabbage vegetables in biochemical and mineral compositions. It is necessary to raise the productivity of cauliflower and to increase the volume of its production in order to expend the range of vegetable market. Hence, it is important to apply new high productive hybrids adapted to the natural climatic conditions of the region in industry and to research the peculiarities to of their marketable quality formation.
The research aim was to estimate the late ripe cauliflower hybrids according to growth, development and productivity of the crop depending on the hybrid peculiarities and the vegetation period conditions in comparison.
Kasper F1, Skywoker F1, Santamaria F1 late ripe cauliflower hybrids were studied in the experimental field and at the chair of fruit, vegetable growing and storing at KhNAU named after V.V. Dokuchaiev under the conditions of the Left-bank Forest-Steppe in Ukraine in 2015–2017.
It was ascertained that the weather conditions influenced the phenological phases of cauliflower more than the hybrid peculiarities. The average durations of the vegetation period ranged from 93 days for Kasper F1 (control) and Santamaria F1 hybrids and to 100 days for Skywoker F1 hybrid during the research years. The dispersal analysis showed that the hight of cauliflower depended on the hybrid peculiarities at 4 % and on the vegetation period conditions at 46 %. The quantity of leaves and a leaf rosette diameter depend on the hybrid peculiarities at 27–29 % and on the vegetation period conditions – at 6‑19 %. During three research years at an average the marketable productivity level of Skywoker F1 hybrid was high (13,7 t/ha).
It was ascertained that the formation of late ripe cauliflower hybrid productivity depended on the hybrid peculiarities by 1 % and the influence of the vegetation period conditions amounted to 91 %.
