Abstract

This article shows that in conditions of high mountains of Tajikistan (at height more than 2700 m above sea level), fertility of pollen grains of Solanum tuberosum L. varies from 5 to 97%. Among clones of potato studied, only 5 to 9.7% had viable pollen grains. Also, in conditions of a mountain zone, big polylithism was established for qualitative traits such as flower coloring, anther coloring and forms of stamen columns of flower of potato. As a result of carrying out crossing of varieties of potato, more than 6 kg of hybrid berries F₁ were obtained. These hybrid seeds will be used in breeding and genetic research works in the future.

Keywords: Breeding, crossing, pollen vitality, hybridization, clone, Tajikistan.
