Screening of Different Cotton (Gossypium spp.) Genotypes for Yield and Yield Parameters

― The experiment was conducted to determine the yield (seed cotton and seed) and yield parameters (plant height, number of sympodial branches, number of boll per plant, seed cotton weight per boll, number of seeds per boll, 100-seed weight and ginning outturn) of different twohundred cotton (Gossypium spp.) genotypes in east Mediterranean climatic conditions using a randomized complete block design with three replications in 2018 and 2019 growing seasons. It was determined that there were statistically significant differences among the cotton genotypes for all investigated characteristics. The results showed that plant height, number of sympodial branches, number of boll per plant, seed cotton weight per boll, number of seeds per boll, 100-seed weight, ginning outturn, seed cotton yield and seed yield ranged between 53.10-110.50 cm, 4.20-12.00 no. plant-1 , 4.50-18.30 no. plant-1 , 2.00-6.40 g, 18.00-40.00 no. boll-1 , 7.70-13.50 g, 26.70-45.50%, 1290.0-6230.0 kg ha -1 and 880.0- 4060.0 kg ha -1 , respectively. As a result, these variations of cotton genotypes can be evaluated in cotton breeding studies for specific purpose
