Eight mutant lines of local Barley “Bakkur” were developed using Gamma irradiation, and planted in plots and rows in Kawkban and Bani–Mater districts under rainfed conditions during 2010 and 2011 seasons along with the mother variety (untreated) and the improved Kawkban-1 variety which predominated in the region. Evaluation was made for all agronomic and biological traits including lodging resistance. Results obtained showed that the Al-erra-B-008-15 mutant was the best in terms of yield increase and early maturity during the two consecutive seasons 2010 & 2011 followed by Al-erra-B-008-20 in compression of the rest including untreated variety and predominant variety Kawakaban-1. The average yield was 2438 & 2235 kg/ha, and 1935 & 2001 kg/ha respectively. The two mutants were matured at 87 and 90 days while 94 and 91 day for untreated and predominant Kawakaban-1 variety respectively. The Al-erra-B-008-15 mutant was distinguished to be resistant to lodging while Al-erra-B-008-20 scored medium resistance as compared to Kawkaban-1 variety. The untreated variety was found susceptible.
