In: Mansoura University Journal of Agricultural Sciences 2009.v.34(2)Summary: This investigation carried out to determine combining ability and gene action estimates for yield and yield components traits with some fiber properties in cotton. The genetic materials in this investigation included five cotton varieties i.e. Suvin (P₁) ; TNB ( P₂) ; Pima S6 (P₃); G.88 (P₄) and G.89 (P₅) and their 30 three way crosses. All these varieties belong to the species Gossypium Barbadense L. In 2008 growing season these all genotypes were evaluated in experimental Agriculture Research Station at Sakha. the following traits were estimated : boll weight , seed cotton yield per plant, lint cotton yield per plant, lint percentage, number of bolls per plant, seed index , lint index , number of seeds per boll, lint per seed , fiber strength , fiber fineness, span length at 50%, span length at 2.5% and uniformity ratio % .
