Abstract
Laboratory screening of local and exotic barley genotypes revealed 2 resistant and 3 moderately resistant genotypes out of 50 entries. Field screening of the same material revealed 4 resistant genotypes at Giza and 6 at Mallawi. Out of 62 Local Barley Crossing Block breeding lines grown at Giza, 3 entries exhibited high resistance, while from 72 ICARDA CB, 2 entries were free of aphids. The level of infestation with aphids at Giza in 1994-95 growing season was moderate to high.
