Abstract

The present investigation deals with the origin of the common bean Giza 6 varielty . Hybridization was practised between the two varie­ties Giza 3 and Swiss Blanc to transfer the genetic factors which control the characters of large seed from Swiss Blanc to Giza 3 variety to devel­op a new variety resistant to common bean masaic virus incorporated with large dry seed. Three lines were selected i.e, 1-1 , 13-16 and 13-6, in 1976 and tested, compared with parents during the years from 1976 tg 1981 . Also , the selected lines were retested again with 4 introduce lines from 1973 to 1988 . Because of the great variation between the plant, individuals within the lines to rust infection, selection of individual plant which exhibited moderate resistance to BCMV and rust inferction was practised. Line 1-1 exhjibited the characterrs of heavy large seeds , high productivity. The selected line, i,e 1-1 was also moderate resistant to BCMV and rust infection line. Line 1-1 is released and given the name Giza , 6.
