Field experiments were conducted during 1995 and 1996 sea­sons in El-Arish, North Sinai, to evaluate eight Egyptian commercial cot­ton varieties (G.barbadense L.) viz. Giza 45, Giza 70, Giza 77, Dandara, Giza 75, Giza 80, Giza 83 and Giza 85. The evaluation was done under drip irrigation using slightly saline water (3480-4160 ppm) during the growth season. The results indicated that earliness characters were found in Dandara, Giza 80 and Giza 83 varieties over the two seasons of growth. Yield and its components were also highest in Giza 80 and Giza 83 varieties. The total cotton seed yield was best in Giza 83, and Giza 80 with mean values of 11.55 11.31 Kent/fed., respectively. For fiber properties; Giza 45, showed the highest fiber strength, whereas, mirco­naire reading (fiber fineness and maturity) were highest in Giza 75, Giza 80, Giza 83 and Giza 85 had the highest value of reflectance (Rd%). Giza 83 and Dandara variety had the highest degree of yellowness and Giza 85 had the highest value of reflectance (Rd%). Giza 83 and Danda­ra had the highest was % and sugar %, respectively. The data suggested that the more suitable varieties to be grown in North Sinai with both highest total seed cotton yield and good fiber properties were Giza 80 and Giza 83. On the other hand, more studies are needed to determine the suitable varieties for each region of North Sinai
