Abstract

The aim of this paper was to determine the correlation between qualitative-technological traits and grain yield as well as the variability of these properties in two-row barley varieties. The experiment was conducted during the period of 2012-2014 on the research fields of the Faculty of Agriculture, in two different locations in the Republic of Macedonia, Ovche Pole and Strumica. The total numbers of 21 genotypes are used as research material, of which 5 are Macedonian, 2 are Croatian, 2 are Serbian and 12 genotypes originate from Bulgaria. The following qualitative-technological traits are analyzed: protein content, grains uniformity of I and II class, water sensitivity, soaking degree, 1 000 grains weight and hectoliter weight. No matter the average grain yield values are higher for tested genotypes grown in Strumica, still the genotypes tested in Ovche Pole presented better qualitative-technological traits. Using the principle component analysis we have determined that as far as qualitative traits and grain yield are concerned, two main components with cumulative percent of variation of 67,60% were identified for genotypes analyzed in Ovche Pole. The variation among the tested genotypes grown in Strumica is higher and were identified three main components with cumulative percent of variation of 70,36%. In both of the locations significant positive correlation was established between the grain yield and 1 000 grains weight. On the other side, negative correlation was obtained between grain yield and grains uniformity of II class. Significant positive and negative correlations between the qualitative-technological traits and the grain yield, for the genotypes of both of the locations were obtained, between: grains uniformity of I and II class, grains uniformity of I class and 1 000 grains weight, grains uniformity of II class and 1 000 grains weight. Key words: correlation, PCA, barley, yield, genotype
