Breeding effect of selection methods (population, seed, and single-plant) at seed sites of various genetic levels in the Volgograd region

Abstract

The article presents methods and results of selection of breeding material of Crimean pine (Pinus nigra subsp. pallasiana (Lamb.)., resistant to various stress factors. The original and promising cultivars for further use in breeding, introduction, competitive and production tests have been identified. With the help of hierarchical variance analysis, it was established that old-age plantings are a source of useful breeding traits and material for further breeding and genetic work.
