G.I. Yarovoy, M.S. Negreba. Hybrids crop capacity of pekingese cabbage suitable for growing in the conditions of left bank forest steppe of Ukraine. Pekingese cabbage, which is remarkable for cold resistance, precocity, high yields and high content of nutrients, occupies a special place among the vegetables with a high content of bioactive substances from the cabbage family. The modern technologies solve the problem of the needs of the population in the consumption of Pekingese cabbage in fresh and processed form due to cheaper production and obtaining consistently high yields. Biological features and soil and climatic conditions of the western region of Ukraine support the creation of optimal conditions for the use of new highly productive varieties and hybrids of Pekingese cabbage. This is especially true of new varieties and hybrids, improvement of the elements of the growing technology (date of sowing, transplanting of seedlings, plants layout, nutrition area, fertilization system) that provide consistently high yields in specific soil and climatic conditions. It becomes exceptionally valuable to ground the measures which are aimed at maximum realization of the genetic potential of the varieties and hybrids of Pekingese cabbage. The experimental studies were conducted on the experimental field of KhNAU named after V.V. Dokuchayev during 2014 – 2015, which is situated in the zone of average and unsteady moistening of the eastern part of the forest-steppe of Ukraine. The climate is temperate and continental. The essential variations of air temperature and precipi tations are possible in the zone. The aim of the work was to determine the yield capacity of Pekingese cabbage hybrids suitable for growing conditions in the left-bank foreststeppe of Ukraine. Eight hybrids of Pekingese cabbage were involved into the research: Bilko F1 is the best late (67 days) hybrid of Pekingese cabbage for storage and growing in autumn. The average crop capacity is 50-60 t/ha. Sprinkin F1 is used mainly for spring and early summer fresh selling, but also shows itself well during summer. Pioneer F1 has good keeping quality and superior taste qualities, highly valued in the commodity output market. The average weight of a head is 1.0 – 2.5 kg. Yield capacity is 85 – 90 t/ha. Yuki F1 is a mid-season hybrid. It is resistant to shooting, tolerant to browning of the tips of the leaves and blackspot. Richie F1 is a fast-ripening hybrid. It is resistant to shooting, tolerant to browning of the tips of the leaves and blackspot. It is resistant to heat, suitable for summer planting.
