The paper states that it is necessary to expand the work in the field of ecological and geographical testing of economically valuable plant objects in the system of Botanical institutions supervised by the Council of Botanical gardens of Russia. The role of unique natural polygons of three Botanical gardens belonging to the Russian Academy of Sciences is emphasized. The main collection funds of the Nikita Botanical Garden are located in the Mediterranean climate zone (Yalta). In the Central Siberian Botanical Garden of Siberian Branch of Russian Academy of Sciences plants are introduced into the culture in the conditions of the continental climate of the forest-steppe of Western Siberia (Novosibirsk). In the Botanical Garden-Institute of Far Eastern Branch of Russian Academy of Sciences the gene pool of cultural and natural flora is studied in the monsoon climate (Vladivostok). The authors describe peculiarities of seasonal development, morphogenesis, organogenesis, ontogeny and reproductive biology of garden roses varieties of the Nikita Botanical Garden selection in three climatic zones. It is shown that in the geographical point of varieties breeding located near Yalta, the influence of climatic conditions leads to the absence of winter rest and natural end of the growing season - it is artificially regulated by the annual February pruning. In the monsoon climate of Vladivostok, the largest number of cloudless days (up to 80%) is observed in winter, which can not affect the vegetation of roses in the open ground, but has a beneficial effect on the development and cutting production of roses in greenhouses. In the forest-steppe of Western Siberia varieties from the groups of tea-hybrid, floribunda, grandiflora, Cordes roses and miniature throughout the study period did not enter the postgenerative period, the final ontogenetic state was g3. The main criterion for the selection of garden roses promising varieties in a continental climate is biomorphological - the ability of annual shoots to bloom. Breeding work with roses in the southern coast of the Crimea is carried out in the open ground, in the continental and monsoon climate - in greenhouses.

Assessment Results

The paper presents results of multiyear work to create and study the collection of Paeonia L. species in the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (CSBG SB RAS) (Novosibirsk), which numbers 13 species of 4 botanical sections nowadays. All herbaceous species of the genus Paeonia, both geophytes and hemicryptophytes, have been safely wintered during 12 years without additional shelter. The study shows assessment results of prospects of the genus Paeonia species representatives. It gives recommendations on landscape design for Paeonia species selection.

A new cultivar of smooth bromegrass (Bromopsis inermis Leyss) Flagman was developed by methods of mass selection and polycross. Breeding and wild forms of various ecological and geographical origins are used as an initial material. The authors of the cultivar: Kazarinova I.N., Polyudina R.I., Straub A.A., Gomasco S.K. Studies were conducted on the Central experimental base of the Siberian research Institute of fodder crops of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, located in the forest-steppe zone of Western Siberia (Novosibirsk region, Novosibirsk district, Krasnoobsk). The cultivar is mid-ripening: the period from the beginning of spring aftergrowing to mowing ripeness is 63-75 days and to full maturing of seeds is 95-111 days. The yield of dry matter is 8.3 t/ha, which exceeds the standard by 8%, seed yield - 0.62 t/ha, higher than the standard by 28%. The dry matter yield of the cultivar Flagman for the fourth year of use exceeded the standard by 23% and reached to 11.4 t/ha. The 1000 seeds weight is 3.0-3.4 g. The plant height is 90-140 cm. Tilling capacity is up to 40 stems per tuft. Foliage varies from 32 to 50% depending on the age of the grass and environment conditions. The resistance of the cultivar to brown rust and helminthosporiosis is higher than of the standard. The copyright certificate No. 71916 and patent No. 9653 were received.

The paper analyzes the dynamics of formation of a collection of Astilbe varieties and species included in the bioresource collection USU 44053 in the conditions of Western Siberia forest-steppe. The ways of further expansion of Astilbe collection fund are substantiated by attracting representatives of the Astilbe chinensis , A. crispa groups; varieties with rhombic, narrow-lobed and pyramidal inflorescences, primarily belonging to the group of colors: red, dark red, purple and dark purple. In contrast to the conditions of the middle zone of Russia in which Astilbe are divided into four groups according to the period of flowering: 1) very early (end of June - July), 2) early (July), 3) medium (mid-July - mid-August) and 4) late (end of August - mid-September), for the conditions of Western Siberia forest-steppe, with intense heat gain in mid-May-early June, the flowering dates of very early and early varieties converge. Accordingly, there are three groups: early-flowering (bloom July 8-10), medium-flowering (bloom from July 15-18), late-flowering (bloom from late July-early August). It is proposed to add a narrow-lobed and pyramidal-drooping inflorescence to the traditionally described forms of Astilbe varieties. The expansion of the set of dwarf varieties from the A. crispa group with strongly dissected fringed leaves gives additional opportunities for a landscape design.

For the fi rst time, the results of studying of varieties and breeding forms of apricot in the gene pool collection of the Nikita Botanical Garden – the National Scientifi c Center of the Russian Academy of Sciences (NBS – NSC) (Yalta, Crimea) on the tolerance to the plum Sharka disease – Plum pox potyvirus (PPV), are presented in the article. The collection includes varieties from diff erent ecological and geographical groups that give us the possibility to present an objective comparative assessment of their susceptibility to phytopathogens. Based on long-term monitoring of the apricot orchards on PPV susceptibility in the collection of NBG-NSC, single aff ected plants were discovered and exterminated. Molecular genetic approaches to apricot breeding for tolerance were demonstrated and PPV tolerant genotypes were selected. According to the results of the research, hybridization was carried out. During the entire period of the research, in order to create genotypes tolerant to PPV, 28 738 fl owers were pollinated and 2 908 hybrid seeds were obtained from which plants were grown. Under in situ and in vitro conditions, new breeding forms tolerant to PPV were obtained. The prospect of biotechnological methods usage for inducing the development of hybrid apricot embryos was shown. The conditions for their culture (trophic, hormonal, and physical) were determined, viable seedlings and plants were obtained in vitro and planted for further adaptation ex vitro and to the open ground. New created plants were evaluated and breeding forms were selected, characterized by tolerance to PPV, good fruit quality and high stable yield. Based on the comprehensive studies, two breeding forms of apricot (‘97 -11 ’and ’97-17’) tolerant to PPV and promising for breeding and commercial cultivation were identifi ed.
