Preliminary yield trial(PBYT): In order to select superior lines for participating in advanced yield trial in next year, 140 barley lines (along with 4 checks) were evaluated during cropping season of 2009-2010 in five moderate stations including Karaj, Birjand, Yazd, Neishabour and Esfahan. Plot size was 6m2. Some traits including: Days to anthesis, resistance to faliar diseases ( Powdery Mildew and Helminthosporium ),percentage of lodging, plant height, days to maturity, cold tolerance, 1000 kernels weight and grain yield were recorded. In overall, based on grain yield average, superiority to the checks, rank mean (R), rank standard deviation and rest of recorded traits, 54 lines were selected. Lines 66, 62, 61, 99 and 67 were the top yielding with 8.185, 7.820, 7.617, 7.550 and 7.547 t/ha respectively. Among the top yielding lines 66 and 67 with the lowest rank mean and rank standard deviation showed the highest stability.
