Plum and cherry plum varieties have been studied. The results are presented.
Promising varieties according to a complex of features and varieties-donors for breeding have
been selected.

One of the main problems occuring during the cultivation of plum in the Moscow
region is connected with the insufficient resistance of its flower buds to frosts in severe
winter. Such winters happen in this region once in 25…30 years and they are characterized by
late autumn frosts, maximum frosts in the middle of winter, abrupt and gradual frosts after
thaw in late winter. Plum yield capacity is in no small measure determined by the
sustainability of its flower buds to frosts, or their winter hardiness according to the
components: 1, 2, 3 and 4. This article presents an assessment of flower bud hardiness of
different types of plums by components 2, 3 and 4, the identification of the most winter-hardy
varieties according to these components has become the main of this article.

As a result of the long-term studying of 18 stock/scion plum combinations the essential
influence of a stock on the basic economic-biological parameters of grafted trees has been
determined. Clonal stocks Novelty, ОРА-15-2, ОР-23-23, which raise the productivity and
stability of fructification of plum cultivars, have been allocated in comparison with seed
stocks. Utro and Yaishnaya sinyaya on OPA-15-2 stock (37 t / ha and 27 t / ha, respectively),
and Skoroplodnaya on OP-23-23 (33 t / ha) gave the maximum yields. The replacement of
seed stocks for clonal stocks improved the stability coefficient from 0.6 to 0.8...0.9.

The estimation results for fungi disease resistance of 31 cherry varieties from different
research organizations during 9 years are given. Promising genotypes resistant to leaf spot,
brown rot and diseases complex have been picked up. Varieties Igritskaya and Spanka
bryanskaya have exposed high and stable resistance. Varieties Radonezh, Soyuznaya and
Novinka from the same group have been less stable from the resistance point of view.
Varieties Morel bryanskaya, Zastentchivaya, Pritchuda, Tchudo vishnya, Lubimitsa, Pamyati
Vavilova, etc. (infection was 1…1.4 point) are in the group of resistant and medium resistant
ones.

The results of observations of the terms of phenological phases for 40 varieties of sour
cherries in the South of the Ukraine for the period 2004...2010 are given, characteristics of
differentiation and organogenesis of generative buds for 14 varieties of sour cherries are specified.
It has been determined that varieties Ozhydanye and Amulet are the first ones to start
the differentiation of buds, variety Igrushka starts later. In conditions of the south of the
Ukraine the generative buds of the studied varieties in winter are in the seventh and eighth
stage of development.
Varieties with the extra-early (Melitopolska radist and Ranniy desert) and late (Kapriz,
Griot Turovtsevoi) fruit maturation terms have been selected. They are valuable for breeders
as initial forms, as well as for fruit crop producers.

As a result of the scientific research work with Lonicera caerulea L.and Hippophae
ramnoides L. in conditions of the Southern Urals (Chelyabinsk) more than 8,831 thousand
hybrid plants have been studied. A register of optimum donors and potential sources has been
created. More than 23 varieties have been developed, 14 of which have been included in the
National Register: Amazon, Bazhovsky, Volschebnisa, Dlinnoplodnaya, Elizabeth, Isuminka,
Lasurit, Lenita, Sineglazka, Sinilga, Stoykay, Fianit, Chelyabinka, Chernichko. Promising hybrid
families have been identified and new elites and cultivars have been obtained.

The analysis of the productivity of introduced varieties of Lonicera L. has been made to
determine the assessment of the environmental sustainability relative to the climatic factors
of the steppe zone of the Southern Urals. The estimation of honeysuckle berries by weight of
fruit and taste depending on the meteorological conditions has been given; the biochemical
composition of fruit has been studied.
For consistent high yields of Lonicera L. in the steppe zone of the Southern Urals it is
necessary to cultivate varieties Volkhov, Viola, Lebedushka, Amphora and Kamchadalka,
which are resistant to climatic stress factors.

The studies have been carried out in the Irkutsk region. 12 varieties and 7 selections of
ever-bearing raspberry have been investigated. The studied genotypes have been estimated
according to the fruit ripening periods. The potential productivity of ever-bearing raspberry
has been characterized according to the weight of a berry in conditions of the south of Irkutsk
region. The perspective forms of ever-bearing raspberry have been selected for growing in the
studied region.

The effects of different concentrations of contemporary preparations containing
physiologically active compounds – «Epin-extra» (action agent – epibrassinolid) and
«Tzirkon» (with hydroxycinnamon acids) on germination in vitro of pollen grains in remote
hybrids of cherry-plum and apricot have been researched. The using of this physiologically
active products in optimal concentration 0,01 ml/l supplemented in the artificial nutrient
media leads to the multiplication of quantity of germinated pollen in cherry-plum variety
Scythians’ Gold and apricot selection №22 at 1,8…9,4 times. The increased concentration 0,5
ml/l of each physiologically active product does not provide stimulated effects on the pollen
germination of these genotypes.

The perspective of using biopreparations Gaupsin (Pseudomonas aureofaciens) and
Trichodermin (Trichoderma lignorum) in the system of peach protection against Taphrina
deformans Tul. and Clacterosporium carpophilum Aderh. is shown.
It was determined that twice-repeated spraying of peaches by biopreparations
hampers the spreading and development of Taphrina deformans by 14.9…26.5% and
2.9…8.3%, respectively, Clacterosporium carpophilum – 9.6…18.2 and 4.2…8.4%. The
effectivity of Gaupsin application (5.0 l/ha) and Trichdermin application (5.0 l/ha) was much
higher against Taphrina deformans than against Clacterosporium carpophilum and was
70…84%.

Shot-hole disease and fruit rot are the nucleus of diploid plum pathogenic complex.
Shot–hole disease is spread in nurseries, young and crop fruit-bearing plantations. The
resistance of 10 plum diploid cultivars to shot-hole disease agent has been studied. Immune
cultivars were not revealed in years of researches, a considerable proportion belonged to
poorly- and medium-affected cultivars. "The critical" periods of plant infection by disease
agents have been preliminary determined. Tortricid plum moth (Grapholitha funebrana) and
plum moth (Hyalopterus pruni) prevailed among pests on diploid plum.
