In this article, a cytogenetic analysis of the karyotypes of the Magnibracteolata Tod section and cotton F1 hybrids was carried out. Karyotypic analysis gives us a set of signs of a complete set of chromosomes inherent in the cells of a given species of cotton, as well as the number, size and shape of chromosomes and an idiogram of these species and subspecies and hybrids. Based on selection of initial species and subspecies using karyological indicators, it is possible to determine the harmony of karyotypes when crossing the Magnibracteolata Tod section and compare F1 plants.
