Garcava E. The estimation and selection of initial material of maize on hot-resistance and drought-resistance

Object - hot- resistance and drought- resistance of selection material, morpho-biological signs, adaptive and combination ability and selection value of the dedicaded lines. Purpose - estimation and selection of initial material of corn is conducted after the level of morpho-biological signs, trained character of varying and feature of inheriting of hot-resistance and drought-resistance. Methods - hot- resistance, drought- resistance and cold- resistance -laboratory and fields methods of estimation. Level of inheriting, adaptive and combination ability -mathematical methods of estimation. Results - efficiency of selection of initial material of genetic plasmas of Lancaster and Ayden and hot- resistance drought-resistance with the use of improved classic and developed physiology methods is established. Features of inheriting signs of adaptiveness is determined. Abilities of display of general and specific combinational ability of the allocated genotypes is established. Sphere of use - Agricultural
