ECONOMICALLY VALUABLE CHARACTERISTICS OF NEW MEDIUM-FIBER BREEDS OF COTTON (G.HIRSUTUM L). AT THE DIFFERENT LEVEL OF WATER SUPPLY

In this article, the economically valuable characteristics of new cotton breeds in dependence of the moisture regime are analyzed. Based on the carried out experiments it is possible to note that the studied breeds have shown individual reaction to deficiency of irrigation water on growth and productional processes. The most labile characteristics under the influence of adverse factors were productivity components, rather stable characteristics were elements of fiber quality (length, yield and grade of fiber).
