Abstract

The aim of this paper was to study the relationship between grain yield and yield related components in spring barley varieties using multivariate analysis.
Five spring barley varieties (Makedo, Xanadu, Josefin Variety, Gladys Variety and Scarlet Variety) were used as an experimental material. Only Makedo was domestic variety and the other spring barley cultivars were introduced. The field trial was carried out on the experimental field area in Probištip, Republic of North Macedonia, during two growing seasons (2013 and 2014). Two row barley varieties were arranged in a randomized complete block design with three replications. The size of experimental plot for each variety and replication was 5 m2. During the vegetative period, all recommended agronomic practices were applied for growing crop. Grain yield and some important yield associated traits, like number of spikes per m2, plant height, number of grains per spike, 1 000 grain weight and hectoliter weight were evaluated. Makedo variety showed the highest value for grain yield (6 844 kg/ha), followed by Xanadu (6 638 kg/ha). Also, Makedo has the highest values for number of spikes per m2 and the number of grains per spike. Principal component analysis (PCA) was utilized to examine the variation and to estimate the contribution of each trait to total variability. Two main components with Eigen value greater than one contributed 82.46% variability existing in the barley varieties for yield contributing traits. PC1 accounted 59.92% of the total variability and the traits like number of spikes per m2, grain yield and number of grains per spike were positively contributing to the first main component. The second PC accounted 22.53% of the variation and 1 000 grain weight was the main highly positively trait of PC2. Only Makedo variety showed positive values among both main components. Grain yield showed positive correlations with number of spikes per m2 (r= 0.795) and number of grains per spike (r =0.632).
