Two cycles of pedigree selection for earliness index and lint yield/plant were achieved in two populations of Egyptian cotton (G. barbadense L.) under late planting condition. The genetic materials were the F6, F7 and F8- generations of (Giza 80 x Pima 56)/Giza 91 (pop. I) and Dandara Giza 80 (pop. II). The geno- typic coefficients of variation gcv) in the F6-genreation were 13.35 and 14.69% for earliness index and 23.70 and 27.60% for lint yield/plant for pop. I and pop. II; respectively. The remained gcv after two cycles of pedigree selection were 8.12 and 10.60% for earliness index, and 22.59 and 21.50% for lint yield/plant for pop. I and pop. II; respectively.
