Biological Features and Economic Valuable Traits of Intraspecific Diversity of Afro-Asian and Indo-Chinese Species of Cotton

Muminov Kh. A. | Ernazarova Z. A.

Abstract: Use of the valuable cotton germplasm of wild rel-atives 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 studying 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 indi-cators 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 enrichment of genotypes in development of new high-quality and highly productive cultivars.
