Abstract
Ninety barley Doubled haploid lines originated from crossing between six barley cultivars in Cereal Research Department, Seed and Plant Improvement Institute, Karaj, Iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. Six parent cultivars and a powdery mildew susceptible check cultivar, Afzal were also included. Sixty two doubled haploid lines showed high levels of resistance and twenty eight lines were susceptible or moderately susceptible, indicating that the crossing program was successful in transferring resistance from parental cultivars to doubled haploid lines. Lines of group B1 (cv. Legia × Rihan) were all resistant while lines of group B6 (cv. Rihan × Legia) were all susceptible to powdery midew. Lines of group B2 (cv. Igra × Riham) with average 211.80 days to maturity were the most early maturity lines, and line of group B3 (cv. Igra × Kavir) with average 56.10g of 1000kw were the most high yielding lines .
