ESTIMATION OF THE VARIETIES WITH DIFFERENT ECOLOGICAL ORIGIN ACCORDING TO THEIR MAIN TRAITS AND PROPERTIES

Abstract

The article presents the results of productivity and grain quality of 47 winter durum wheat varieties of various ecological origin studied in 2016–2018. All studied samples belong to semi-dwarf and dwarf forms (height of 61–105 cm). Semi-dwarf forms possessed high lodging resistance (3.9 points). The grain harvest of the main part (89.3%) of the samples ranged from 8.41 to 9.65 t/ha in the environmental test. Only three varieties (“Lazurit”, “Agat Donskoy”, “Andromeda”) in the winter durum wheat trial are characterized with high yields ranging from 9.65–10.0 t/ha. The yield of the standard variety of “Khristella” was 9.03 t / ha on average in 2016- 2018. The varieties “Kondor” (116.8%), “Zolotko” (123.0%), “Afina” (126.9%) showed high frost tolerance of the plants through the years of research, in comparison with the standard variety “Donchanka” (100%). In the ecological test the main part (68%) of winter durum wheat varieties possessed large grain. “1000-grain weight” was more than 40 g: “Amazon” (42.9 g), “Lazurit” (47.7 g), “Diona” (42.1 g), “Alyi Parus” (43.7 g), “Dnepryana” (45.4 g), “Krupinka” (46.9 g), etc. The studied samples had high percentage of protein (13.6–15.1%), gluten (22.8–27.0%), SDS-sedimentation (30–45 ml), carotenoids (468–779 μg/%), nature weight (777.0–819.0 g/l), kernel hardness (85–98%). The technical and culinary qualities of the pasta made from the main part of the samples were evaluated as excellent (the varieties “Donchanka”, “Oniks”, “Kiprida”, “Atoll”, “Kermen”, “Winter Gold”, etc.) and as good (the varieties “Teya”, “Eirena”, “Lazurit”, “Diona”, “Alyi Parus”, “Krupinka”, “Afina”, etc.).
