The main purpose of this research is to compare the bio-morphological properties, fiber properties, technological quality indicators and net return levels of different cotton varieties, to include different varieties in hybridization and to use the obtained hybrids as a starting material in selection. The research was carried out in the experimental area of the Plant Protection and Technical Plants Scientific Research Institute in Samukh district in 2017-2020. Research material consisted of the local Ganja-110 cotton variety and some cotton varieties S-6524 (Uzbekistan), BA-440 (Turkey), Akala Beret (Israel), Selekt (Greece), Tashauz-68 (Turkmenistan) brought from cotton growing countries. The results of this research revealed that cotton varieties differ from each other in terms of raw cotton yield, this yield indicator was 4,380 kg/ha in Ganja-110 cotton variety against lower yields in the other varieties. The raw cotton mass of the Ganja-110 cotton variety was 6.3 g in a boll while it varied 5.2-6.0 g in a boll for the other different cotton varieties. It has been determined that the net return of other cotton varieties was also lower than Ganja-110 variety. It is recommended to use hybrids with enhanced heterosis effect obtained from crossbreeding between different cotton varieties.
