DELIBALTOVA, V. and Hr. KIRCHEV, 2010. Grain yield and quality of bread wheat varieties under the agroecological conditions of Dobroudja region. Bulg. J. Agric. Sci., 16: 17-21

The field experiment was conducted in the selected area of Uzovo village, Dobrich area in the period 2004-2007. The test was performed by means of a block method with four replications; experimental field area - 15 m2 after sunflower predecessor. The following wheat varieties were tested; Albena, Pryaspa, Enola and Karat. The aim of the study was to establish the grain yield and quality of four Bulgarian bread wheat varieties, grown in the region of Dobroudja.The analysis of the results showed that under the agroecological conditions of Dobroudja region the highest grain yield was obtained from Karat variety - 6000 kg ha-1, followed by Albena - 5300 kg ha-1 and the lowest one - from Enola variety 5130 kg ha-1.The test weight of the investigated varieties is close values, witch indicates that it is in effect - largely on the weather conditions of the year, rather than the variety. The thousand kernel (grain) weight and wet gluten content of Albena variety were highest (50.7g and 28.0%) and lowest of Enola - (46.51g and 26.0%). The lowest values of relaxation of gluten reported with the variety Albena - 7.3 mm and the highest - with the Karat variety - 9.8 mm.
