This research was done to compare 15 double haploid lines and 15 Persian varieties by measuring physicochemical properties of barley seeds. Seven properties that were related to high quality malting, were studied in a Completely Randomized Design (CRD) using 3 replications, at the university of Tehran in 2012. There was negative correlation between protein content and malt extract, but the correlation α-amylase activity, diameter and length of grain were not significant. Principal components analysis classified seven physicochemical properties in to 2 new components. The first component explained 45.97% of total variations that mainly included diastatic power(  L ), malt extract(%), α-amylase activity, protein content, kernel weight and grain diameter. The second component explained 18.56% of total variations that mainly included grain length. Analysis of these clusters showed that most of DH lines and some of persian varieties such as Dasht,Valfajr, Sahar and Kavir were suitable for production high quality malting processes.
