Abstract:

This paper presents the results acquired from the study of eight carrot hybrids which are suitable for growing in the climatic zone of woodland steppes, while considering a set of economical and/or biological, biochemical, and organoleptic properties. The carrot hybrids that were studied have a wide range of variation in their economic value indicators, which makes it possible to grow them for storage and processing in various soils and climate conditions without irrigation. The most productive carrot hybrids are White Sabine F₁ and Yellowstone F₁ with a commercial yield of 55.8–58.7 t hа^–1 and an average taproot weight of 118.7–136.2 g. The levels of preservation of the taproot of the hybrids White Sabine F₁ and Purple Haze F₁ after seven months of storage in conditions that involved the use of a stationary pit storage facility was at 81.4% and 80.2% respectively. The use of the taproots of the hybrids Yellowstone F₁ and Viking F₁ for drying ensures a yield of a high-quality, biologically-valuable finished product with a yield of 11.4–11.7%. Dry hybrid Evolyutsiya F₁ and Mars F₁ carrots contain more than 40 mg (100 g)^–1 of β-carotene.
