Abstract: This study was conducted during the 1997-2000 growing seasons at the Agricultural Faculty’s experimental fields of Kahramanmaras Sutcu Imam University. The cultivars of Maras-92, Sayar-314, Cukurova-1518, Nazilli-87 and the Agdas-3 cotton variety obtained by mutation breeding in Azerbaijan were used as a material. High voltage electrical current (30 KV 30-1 sec.) was applied to seeds prior to sowing using the CORONA shocking instrument from Azerbaijan. Shocked and unshocked (control) seeds were grown in field experiments using a split plot four block experimental design over four growing seasons. Our goal was to test whether high voltage electrical shock would increase yield and fiber quality traits of the tested cultivars. We found that high voltage electric current can be used in large scale production to reduce the sowing-germination interval and time to first boll opening, while increasing sympodia number, bolls per plant and seed cotton yield. Shock treatment shortened the sowing-germination interval and time to first boll opening both by 3 days, allowing harvest 6 days earlier. Shocked groups averaged 2 more sympodia and bolls per plant compared to controls and had improved cotton yield. The early maturing Agdas-3 variety had the shortest germination and first boll opening times and the highest sympodia number but the lowest seed cotton weight per boll. According to the four years’ results, it can be said that the treatment of high voltage electrical current has a little positive stimulative effect on fiber technological traits.
