Abstract
Use of the valuable cotton germplasm of wild relatives in works of improvement of cultivars and develops of new ones, meeting modern requirements, is for the present limited by a blank in our knowledge of all biological and morphological diversity. On the basis of study-ing and an estimation to morphological and biological and economic-valuable traits of representatives of an intraspecific diversity of species G.herbaceum L. and G.arboreum L. It is determined that as a whole, are characterized by photoperiodicity, low indicators of cotton raw weight per boll, length and a fiber output. Low indicators of components of productivity, photoperiodicity and late maturity indicate in their wild nature. Attraction of wild forms as an initial material in genetic and breeding research gives the chance for en-richment of genotypes in development of new high-quality and highly productive cultivars.
Keywords: evolution, cotton, subspecies, varieties, 50% germination - maturation, fiber length, fiber output, raw cotton weight per one boll.
