Using Genetic Statistical Methods in Creation of Cotton Plant Varieties in Uzbekistan

The analysis of selective and genetic parameters of 5 cotton plant families and their 20 hybrid combinations, obtained by means of diallel crossing scheme under the conditions of Uzbekistan. The main consistencies ofgenetic determination of one-boll mass of raw cotton are determined by the methods of statistical genetics. Basing onthe study of hybrids, the genetic sources with the high general and specific combining ability of one-boll mass of rawcotton are allocated, basing on which TashDAU-100 cotton plant variety is created and transferred to the National Measurement Assurance System.
