Cluster analysis of valuable economic traits in amphidiploid cotton hybrid plants

This article reveals cluster analysis of farm-valuable traits of the plants of primary sources and interspecific amphidiploid F1-F6 generation. According to research results, a considerable variation was observed on the traits of F1-F6 plants belonging to various cluster. It was 2,3-6,2125. by the weight of cotton in one boll, by the weight of 1000 seeds 67,3-125,529 g., by fiber length it made 24,9-34,4125 mm, by fiber yield 31,4-40,2625 %, and according to fiber index 6,3-7,5875 g. Furthermore, among F6G.hirsutum subsp. euhirsutum “Kelajak” variety х F1(G. arboreum subsp. perenne x G. arboreum subsp. obtusifolium var. indicum) combination families, the plants were isolated with high indicators according to their traits on cotton weight in one boll up to 6,6 ± 0,13 g. (“Family-41”), by weight of 1000 seeds 125,8 ± 3,48 g. (“Family-59”), by fiber length 34,5 ± 0,16 mm (“Family-8”), by fiber yield 40,3 ± 0,65 % (“Family-59”), by fiber index 8,5 ± 0,23 g. (“Family-59”). Plant analysis using this cluster method allows the prediction of families with high combinatorial ability. The forms isolated from higher generation (F5 G. hirsutum L. x (G. arboreum L. x G. arboreum L.) “Family-5”, “Family-13”, “Family-8”, “Family-59”, “Family-14”, F6 G. hirsutum L. x (G. arboreum L. x G. arboreum L.) “Family-13”, “Family-5”, “Family-59”) plant families, fill the cotton gene pool as valuable recombinants, and in future they can be used in genetics, breeding research as valuable donor.
