INTRASPECIFIC VARIABILITY OF MULTIFLOWERED OLEASTER

Abstract

A study was carried out about the basic biological features of multiflowered oleaster plants: growth and development of the above-ground part, growth and placement of the root system, seasonal development rhythms. There is given the breeding assessment of oleaster collection samples as to winter hardiness, self-bearing, yielding capacity, fruit quality, resistance to diseases and pests, thorniness of shoots, and bush habit. The oleaster sampling was performed as to specified characters and their highest possible complex. The promising forms and potential donors of the most important economic and biological characters were selected. The following cultivars have been developed: Sakhalinskiy Pervy, Moneron, Krillyon, Yuzhny, Shikotan, Kunashir, Cunai. Peculiarities of the sample formation process in the progeny from open pollination were established.
