The research was carried out at the field experiment station and cotton technical specifications laboratory during the 2021 and 2022 seasons. The cotton research institute evaluated the performance of some cotton genotypes grown in Delta, including two commercial types, Giza 94 and Giza 97, and two promising crosses ((G86 x (S106 x G89) x G94)) and S111 X ((G86 x (G77 x G81)). All samples were spun into three yarn counts using a ring-spinning system. The results showed that there were significant differences between genotypes in terms of yield, fiber and early yarn characteristics, seed cotton yield, lint yield, lint value, micronaire, evenness, and hairiness when Giza 94 was compared with other genotypes in two seasons. On the contrary, the promise of cross breeding G.94 x G.89 x S106 x G.86 was clearly superior to other cottonseed genotypes in terms of lint yield and lint value. Although it has the lowest strength, it has the highest short fiber index and hairiness. Promising hybrids can be isolated and used in breeding programs to increase seed and lint yields of Egyptian cotton varieties.
