Potato breeding in mountainous and foothill areas

Abstract

The work is to develop new competitive potato varieties. The studies were carried out in mountainous conditions on mountain meadow soils in a zone free from viral infection. According to the scheme of the breeding process, in the parent nursery, hybridization was carried out in 18 combinations, 16837 seeds were obtained. In the preliminary test nursery, 3 hybrids formed yields of over 50 t / ha. High yield of hybrids was also noted in the nursery of the main trial. Of the 7 hybrid offspring in the nursery of the 1st year competitive trial, 4 provided a yield higher than the standard variety. Hybrids 13.61 / 66 were isolated from 4 hybrids of the II year competitive test nursery. In the nursery of the third year competitive test, all tested hybrids formed a high yield (2.1-45.5% higher than the standard). The 10.11 / 770 hybrid has been submitted for state testing. Hybrid 10.11 / 765 (Osetinsky variety) is included in the State Register of Breeding Achievements.
