Nowadays, the demand for organic products is increasing. Breeding of naturally colored cotton allows for saving the high costs of dyeing the fiber and obtaining a natural product that is harmless to the human body. Natural colored fiber has air permeable, antiseptic and hydrophobic properties. However, the use of natural colored cotton in the textile industry is limited due to its low fiber quality. Solving this problem requires interdisciplinary research on colored cotton. In the article, morphological traits of natural brown and green cotton cultivars of G.hirsutum L. cotton - duration of vegetation period, plant height, leaf shape, color and hairiness of the main stem, boll shape, type of sympodial branching and fiber color also, agronomic traits - a boll weight, fiber yield and index, fiber length, weight of 1000 seeds were determined and analysis results were presented. The obtained results showed that the brown cotton samples are medium-ripening, the green cotton cultivars are late-ripening, and the plant height of the green cotton cultivars is higher compared to the brown cotton cultivars. Fiber length was longer in the cultivars cone-oval shape of boll than in cultivars with round shape. Fiber length was higher in green fiber cultivars A-800 and 010764 than dark brown fiber cultivars 011250 and 010108. In contrast, brown fiber cultivars had higher indicators than green fiber cultivars in terms of fiber yield, index and boll weight. Green cotton cultivar 011460 with low fiber yield had the highest index of 1000 seeds weight. In terms of cotton yield, dark brown fiber cultivar 011250 (97.4±2.0g) showed a higher index compared to other cultivars. This shows that cultivar 011250 can be used as a raw material to increase the yield of colored cotton. [ABSTRACT FROM AUTHOR] |
