The introduction and spontaneous hybridization of blackcurrant (Ribes nigrum L.)

Смородина черная (Ribes nigrum L.) является одним из полезных окультуренных видов. Приведены сведения о достижениях в его интродукции и селекции в XIX − XXI столетиях. Интродукция, отдаленная гибридизация и посев семян от свободного опыления зимостойких, урожайных и крупноплодных культиваров данного вида позволили отечественным селекционерам создать ряд выдающихся сортов, объединив географически разобщенный генофонд. Чаще других интродуцентов при отдаленной гибридизации использованы старые западноевропейские сорта ‘Голиаф’ и ‘Бредторп’.

Proposals for establishment of genetic reserves of Juniperus communis L. and J. sabina L. in the South Urals

Authors: Putenikhin V. P., Farukshina G. G.

It is suggested that genetic reserves intended on preservation of the most valuable gene pool of plant species may be established as botanical nature monuments. Two genetic reserves in populations of Juniperus communis L are recommended for establishment. in the South Urals (in Bashkir Cis-Uralian and Mountain South- Uralian populations). In J. sabina L. presented in the region as single population, two genetic reserves are also proposed (in mountain and in Trans-Uralian steppe parts of population).

The study of seed productivity of Allium hymenorhizum Ledeb. (Alliaceae) in culture in the Republic of Bashkortostan

Authors: Elizareva О. А., Galikeeva G. M., Maslova N. V.

The article describes the seed productivity of rare relict spe-cies Allium hymenorhizum (Alliaceae) in culture in the Republic of Bashkortostan. The potential possibilities of seeds formation are realized on 17,7–40,1 %. The correlation between the basic parameters of seed productivity and the year of obtaining seeds and the origin of the sample is established.
