Abstract
The objective of this study was to investigate newly created lines and regionalized varieties of two-row barley by yield and some economic traits, as well as to establish the possibilities of using them in the crop breeding program. To achieve this purpose a research was carried out at the Institute of Agriculture in Karnobat in the period of 2011-2013. Subject of study were 4 regionalized varieties and 6 newly created lines of winter two-row barley. The experimental design was a randomized block method in four replications. Data was obtained on grain yield (t ha-1); biometric measurements were taken for several traits: spike length, number of spikelets per spike, number of grains per spike, grain weight per spike and 1000-grain weight. Two-factor analysis of variance, PC and cluster analyses were used. The results of the investigation showed that out of the tested lines of winter two-row barley, the yield was greatest Кt 1241, Кt 1239 and Кt 1228. The lines of the first cluster, which formed longer spikes and could cross with Кt 1241, are suitable for source material. Line Kt 1241 distinguished by heaviest spike and biggest grain, which allows its successful inclusion it various breeding programs. It is characterized by high grain yield, which makes it suitable for further testing as a variety
