Clipatype breeding features of Pinus sylvestris L. cv. Negorelskaia [Articol]

Abstract

How can a new cultivar of Pinus sylvestris L. cv. Negorelskaya, ecologically sustainable and with increased productivity, be obtained by breeding 65 climatypes of Scots pine? The breeding of cultivars of higher plants has always been of interest and often occurred during the succession of several generations of scientists. The first generation of scientists founded the primary in 1959, and the secondary provenance trial plantation in 1965. The second generation continued the breeding process and received a breeder's patent in 2014. The first seed production of clones of Pinus sylvestris L. cv. Negorelskaya on a grafted forest-seed plantation begins at the age of 5; at the age of 15-17, the actual yield of varietal seeds on a hybrid-seed plantation is 11-15 kg per 1 ha.
