Abstract
Two field experiments were conducted in Mallawi Agricultural Re­search Station, El-Minis Governorate in Middle Egypt, during the two growing seasons 1994/1995 and 1995/1996 to evaluate ten intro­duced barley genotypes for high yielding potential and resistance to the corn leaf aphid (Ropalosiphum maidis F.). Local variety Giza 124 was used as check. The results revealed that three genotypes (No. 21, 22 and 62) were resistant to aphids. Genotypes No. 21 and 22 possessed high yielding potential with high resistance to aphids. The tallest geno­type was No. 24, while the longest spike came from genotype No. 15. The heaviest grains was obtained from genotypes No. 10 and 15. Geno­types No. 21, 15, 62 and 22 had the highest tillering capacity as well as number of spikes/unit area and straw yield (ton/fecl). Genotypes No. 10, 24, 21 , 22 and 27 proved high potentiality and moderate resistance to aphids under Middle Egypt conditions.
