Abstract EN
Two populations of Egyptian cotton (Gossypium barbadense L.) derived from the crosses Giza90 x Giza85 (population I) and Giza90x Giza80 (population II) were subjected selection by two methods, i.e.
pedigree selection (PSM) and bulk selection (BSM).
The selection criteria were seed cotton yield per plant, number of bolls per plant and earliness index.
Results indicated that analysis of variance revealed highly significant differences among families of F3and F4 generations in the two populations except earliness index in popII.
Under F4 progenies had the highest means for all traits in the two crosses except for earliness index in popII compared to F3 progenies.
The mean values for seed cotton yield per plant, lint yield per plant, lint percentage, number of bolls per plant, boll weight, seed index, earliness index and days to first flower in population I and II were higher by PSM than BSM except for earliness index in popII.
Therefore, PSM was more effectives method for cotton breeding compared with other method.
Correlation values for F4 indicated that seed cotton yield/plant was positively correlated with lint cotton yield / plant, bolls per plant and boll weight
