Clustering and principal component analysis of Barley (Hordeum volugare L.) Landraces for major morphological traits from North Western Ethiopia

Melkamu Enyew*, Tiegist Dejene, Berhane Lakew and Fisseha Worede

Huge collections of barley landrace genotypes in Ethiopian are not studied for the magnitude of genetic distances from each other. Though knowing the contribution of individual traits is crucial to focus on particular traits in cultivar development; the traits of these genotypes are not yet studied. Hence, this experiment was conducted on 48 barley landrace accessions which were not studied yet and four standard checks to estimate the magnitude of genetic diversity among the genotypes and to identify the major morphological traits contributing for the observed variations. The experiment was laid in Augmented Randomized Complete Block Design in six blocks at Adet in 2016/17 cropping season. The traits used for analysis were days to 50% heading, days to maturity, plant height, total number of tillers/plant, effective number of tillers/plant, number of spikes/plant, spike length, average number of grains/plant, biomass yield/ha, thousand grain weight/gm, grain yield tones/ha and harvest index tones/ha.
