Селекційно-генетичні аспекти селекції озимої пшениці та їх вплив на агроекологічну адаптивність

Abstract

In irrigated conditions, the realization of indicators of the elements of the crop structure is much higher than in less favorable conditions of non-irrigated agriculture. These studies confirmed the fact that the selection of genotypes resistant to adverse environmental conditions should be carried out only after their high potential productivity has been proven under favorable growing conditions. It is known that 50–80% of the total variability depends on the conditions of the external environment. At the same time, the sign of the stability of winter wheat yield is due to the preservation of the stable value of some elements of productivity and tolerance of other signs.
