Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department Of Agronomy Summary: Diallel crosses (except reciprocals) were made in 2001 / 2002 season between 8 parents of wheat (Triticum aestivum) that varied in resistance to aphidsIn 2002 / 2003 season parents and F1 , s were evaluated for resistance to bird cherry - oat aphid (BCOA) and greenbug (GB) under field and greenhouse conditionsThe main objective was to study type of gene action , combining ability and probable number of genes controlling resistance to these aphidsResults of artificial infestation indicated that general (GCA) was more important than specific (SCA) combining ability variances in determining the plant reaction against both aphid speciesThe best general combiner was Bush and Gz - 170 for resistance to BCOA and Gem - 9 and Sd - 1 for resistance to GBThe best F1 crosses in SCA effects were identifiedOverdominance was the type of dominance controlling resistance to both aphidsHeritability in narrow sense was 410 and 224
