Abstract

Widely spread natural negative mutations in the Triticum genus, the divergence of members of the complementary systems of depression, their concentration in different eco-geographical zones, depending on their biotype and variety leading to the appearance of depressive hybrid plants cause serious difficulties in breeding process. To overcome hybrid dwarfism, the impact of mineral fertilizers (N90P90K75) on the growth and development of Dwarf I and Dwarf II wheat hybrids was studied. Creation of suitable growing conditions revealed, that contrary the increase in vegetative mass of hybrid Dwarf I (plant height, number of leaves, weight per plant) and elements of productivity of hybrid Dwarf II (plant height, productive tillering, the length of the main ear, grain yield per plant) in none of the hybrids the overcoming of depression was registered.
