Abstract: During the period of 2008-2011 in south-east Bulgaria a field experiment was researched. The varieties bread wheat Sadovo 1, Aglika , Enola and Milena were studied. The experiment was applied in block design with 4 replications and 15 m2 plot size, after predecessor sunflower. The growing of plants was performed in compliance with the standard technology. The aim of the study was to establish the grain yield and quality of four bread wheat varieties, grown in Southeast Bulgaria. The analysis of the results showed that the highest grain yield was obtained from Enola variety – 6057 kg ha-1, followed by Aglika – 5777 kg ha-1 and the lowest one – from Sadovo1 variety 5060 kg ha-1. The test weight of the investigated varieties is close values; wich indicates that it is in effect – largely on the weather conditions of the year, rather than the variety. The thousand kernel (grain) weight of Aglika variety were highest - 49.7g and lowest of Sadovo 1 – 43.4g. The grain of variety Milena produce was highest vitreousness – 81.7 % and variety Aglika lowest –66.5 %. Milena variety show the best values (29.1 %, 10.4 % and 5.7 mm) of the investigated technological properties of the grain (wet gluten, dry gluten and relaxation of the gluten)
among the tested varieties winter wheat.
