Genetic diversity of Ethiopian barley (Hordeum vulgare L.) genotypes based on multivariate statistical analysis for acid soil tolerance
Tigist Shiferaw and Mesfin Tadele
Soil acidity is now a serious threat to barley production in most high lands of Ethiopia. Three hundred twenty (320) barley genotypes were evaluated in 2017 main-season, at Holeta Agricultural Research Center using 20x16 Alpha Lattice design under two-soil conditions (limed and unlimed). The objectives of the study were to evaluate the genetic variability among barley genotypes for soil acidity tolerance using multivariate analysis. Barley genotypes were classified into thirteen, sixteen and twelve clusters under unlimed and limed soil condition and by stress index cluster analysis, respectively. Principal component analysis exhibited 81% and 78% of total variation under unlimed and limed soil condition respectively. Phenotypic diversity index was very high for ear attitude, kernel row number and Kernel color and comparatively low for spike density.
