Abstract: Genetic variability is necessary for genetic improvement of any crop. The knowledge on available genetic variability and relationships between economic yield and yield associate traits is important to understand and its potential use in breeding programs. The present study was done at research field of Regional Agricultural Research Station (RARS), Dipayal, Doti during winter seasons of 2014/15 and 2015/16 under maize based bariland system to assess the genotypic variability and correlation among yield and yield components. Fifteen barley genotypes including two check varieties were studied in Randomized Complete Block Design with 3 replications in each year. Statistical analysis revealed the presence of significant genetic variability among the tested genotypes for yield and yield attributing traits. On the basis of yield, seed boldness and maturity period genotypes B86152-2-2-2-OK, XVeola-13, COQ/K1/DESC11 were found promising and could be new barley varieties or as serve as parents for use in breeding programmes to develop high yielding varieties. The positive correlation of grain yield with spike length (0.46**), straw yield (0.44**), tillers/m2 (0.43**), spikes/m2 (0.29**), plant height (0.26*) and thousand grain weight (0.25*) showed possibility of yield enhancement thought selecting in favour of those traits.
