Fifty-nine varieties/genotypes of cotton (Gossypium hirsutum L.) collected from various cotton research institutes in Pakistan were grown in the field. Five cotton cultivars were selected out of this germplasm contrasting for three fiber quality traits viz. staple length, fiber strength and fiber fineness. Three crosses were made using these five genotypes each between two varieties contrasting for one fiber quality trait, cross CIM-707×4-F for staple length designated as cross-I, cross NIAB-111×RH-1 for fiber strength designated as cross-II and cross MS-40×4-F for fiber fineness designated as cross-III. Four generations P1, P2, F1 and F2 of each cross were developed and evaluated in the field. Measurements were made relating to various seed cotton yield and fiber quality components. Results revealed significant differences for all the traits under study.
