YIELD AND FIBER QUALITY CHARACTERISTICS OF SOME COTTON (Gossypium hirsutum L.) CULTIVARS GROWN IN THE SOUTHEASTERN ANATOLIAN CONDITIONS

Abstract

The aim of this study was to determine cotton cultivars for high yield and fiber technological characters in Southeastern Anatolian ecological conditions. For this purpose, the study was carried out with 11 cotton (Gossypium hirsutum L.) cultivars in 2019 and 2020. Field experiment was designed based on randomized complete block design with four replications. The results of combined analysis indicated that there were significant differences between cultivars in terms of yield and quality parameters except for the number of monopodia, fiber strength and fiber fineness. It was determined that cv. Edessa and cv. PG 2018 were superior to other cultivars for seed cotton yield, in respectively 4006.25 kg ha-1 , 3971.42 kg ha-1 . While these cultivars had higher fiber yield than all others, they were the least affected by the year difference. Cv. PG 2018 also had the highest plant height and ginning turnout. It was concluded that cv. Edessa and cv. PG 2018 are more suitable for cultivation in Batman ecological conditions.
