In order to study o relationship between agronomic characteristics in barley, 18 genotypes including advanced lines obtained from barley breeding national program with Nimroz and Auxin as checks were studied in Randomized Complete Block Design with 3 replications in 2018. Studied traits included number of days to heading, days to flowering, plant height, 1000-grain weight and yield. The highest and lowest significant correlations were observed between yield with days to maturity (0.764 **), and 1000-grain weight with days to maturity (0.470*), respectively. The correlation between yield with 1000-grain weight was positive (0.475) and significant at the 0.05 level of probability. 1000-grainweight had positive correlation with number of days to heading and maturity. While, there was no significant relationship between plant height with other under studied traits.
