The article mentions that the special attention is deserved by such persimmon varieties being included into the collection of Garden: Nikita Burgundy – the most famous of the hardiest varieties, widely used in industrial horticulture grade foreign breeding Hana Fuyu and a new, high-yielding variety of domestic breeding Souvenir of Autumn. Plant varieties included into the studying, grow in the same conditions at the collection site, which is located 200 meters from the coast at a height of 20-40 m above its level. Trees are 15 years old, planting scheme is 6x6 meters. The selected varieties belong to the group of constant tart on their quality whose fruits are edible only when fully ripe Varieties are characterized by high winter hardiness and disease resistance, which allows minimizing the chemicals using for plants treating and creates the conditions for organic food. The chemical composition fruits studying of three oriental persimmons varieties have performed high content of potassium, so it affords their using as a general tonic. The obtained results have revealed that according to the content of essential elements the leading fruit of variety Souvenir Autumn is considered to be, the less valuable are fruits of Nikita Burgundy, and Hana Fuyu fruits on this indicator are intermediate.

In the article the authors show outcome of three years observation of blackcurrant varieties bred by Study Horticulture Department NULES of Ukraine for their suitabi­ lity to machine harvesting. Blackcurrant is the most common berry crop in Ukraine. When establishing intensive industrial plantations the varieties suitable for machine harvesting should be used. During 2006-2008 limited and unlimited traits of varieties bred by NULES of Ukraine suitability to combine harvesting were studied. All parameters of the examined varieties were compared against the requirements of the «ideal variety”. Simultaneous ripening of berries was observed in varieties Dochka Vorskly – 93,6%, Hovtva, Pamyaty Leonida Myhalevskoho – 92,6%. The pick off effort required to collect berries out of their clusters for all varieties but Yarynka was within acceptable range of 67...129 g. By effort applied for berries crush only Yarynka has failed to meet the necessary requirements. All the varie­ ties but Yarynka have been found suitable by growth habit of their bush (upright and semi-spread). Insufficient number fruits (6-7 pc.) in clusters for varieties Narodna and Yarynka was noted. Berries weight for all studied varieties ranged within 1.27-1.84 g, their drop-off was 3-8%, duration of harvesting period ranged from 8 to 10 days, so all the parameters of varieties suggested they were suitable for picking berries by berry harvesters. Varieties Dochka Vorskly, Universitetska, Hovtva, Pamyatna, Premiera, Narodna, Leleka and Pamyaty Leonida Myhalevskoho were selected as suitable for combine harvesting by the complex of positive parameters.

The article presents summary of studying the efficiency of dry carrot production when growing in the conditions of Ukraine’s Forest-Steppe subject to a variety. A complex assessment has been completed for fresh and dried products of 10 different varieties and hybrids of carrots on the content of basic biochemical, economic and biological indicators in order to highlight the best suited for drying. Varieties have been singled out, which roots display the highest yield, best marketability, accumulate the most of dry matter, sugars, etc. A close direct correlation between the weight of roots and their marketability has been established. An evaluation of the tested roots for complex organoleptic characteristics has been completed. It is proved that carrot drying is profitable. The yield and dry matter content in roots are key influence factors on profitability of dry carrot production. By the set of parameters under studying varieties most suitable for drying, Krasniy Velikan and Dlinnaia Krasnaia, have been selected. Profitability of their drying exceeds 40%.

In 2011, Blago soft winter wheat variety state examination was completed so that the variety was listed in the National Register of Plant Varieties of Ukraine. Recommended area of dissemination included Steppe, Forest-Steppe and Woodlands. The Blago variety has been developed in the Institute of Irrigated Agriculture at the NAAS of Ukraine and is suitable for cultivation under the conditions of irrigated farming and regular (nonirrigated) farming. This is the only research institution in Ukraine that develops winter wheat varieties for irrigated farming following specific program. As is generally known there are specific conditions at irritated plots. Increased moisture of soil and air, root nutrition mode sufficiently balanced with the elements required constitute special microclimate for the agrocenosis of winter wheat at irrigated soil, which ensure sustainable and high yields across space and time. Nevertheless, not only these conditions facilitate the varieties of wheat, but pests and pathogens as well, thereby maliciousness of the latter, especially that of the diseases, significantly increase compared to nonirrigated crops. The yield potential for Blago as a new variety of winter wheat makes 9 to 10 tons per hectare, and is implemented at irritated lands of the South, as well as in the Woodland and Forest-Steppe of Ukraine. The variety represents a comprehensive use genotype as its high adaptability enables it to be applied as at irrigated, so at nonirrigated lands. The variety is well-balanced in terms of its value for cultivation and use traits.

The article proves that a number of international legal documents revealing a common approach to scientific and methodological providing of qualified examination execution of new plant varieties, patent protection to plants variety are made. Adherence to common methodological approach will promote harmonized description varieties at international level. Criteria to the varieties with example characteristics are considered in detail according to the provisions of the International Convention for the New Plants Varieties Protection, UPOV technical standards. A collection of varieties with example characteristics are formed by the collection of commonly familiar varieties possessing one or more stable characteristics that can be applied as a example for comparison of new varieties used in the qualified examination of the candidate variety uniformity. The requirements to the example variety formation and their using, definitely, the seed samples presence, its morphological description, the marked example characteristics identifying to the botanical taxon are revealed.

Molecular selection (MAS) makes the newest trend in breeding that has been progressively applied in many agricultural crops, including sugar beet. The article reviews papers on sugar beet MAL in Russia and overseas consi­ ering the methods applied and results obtained, das well as prospects for further development of this trend.

The example of various varieties and hybrids of sugar sorghum illustrates the summary of study on assessing varying density of plants in crops on phonological cha­racteristics of sugar sorghum plants, carbohydrate composition of sorghum juice and yield of its plants. The completed study established that one hectare of sugar sorghum, subject to varietal characteristics and varying density of plants in crop, may provide the green weight of 40.83 до 106.87 t/ha at stem juice yield of 22,27 to 56,24 t/ha, which would contain 2.31 to 6.09 t/ha of total sugars suitable for bioethanol production in at the rate of 198.25 to 501.19 dal/ha. However, despite of higher estimate of total sugars yield and bioethanol at 300 thousand plants per ha density in crop, industrial plots would preferably have plant density in crops ranging within 200...250 thousand pieces per ha. Since higher density increases dry matter content of plants, consequentially, cellulose and lignin in stems, this may create preconditions for harvest losses due to stem lod­ ging Besides, 200 thousand plants per hectare enables to reach the highest level of photosynthesis net productivity which combines high intensity of the photosynthesis with photosynthetic activity of leaf surface.

The trend for development and spreading of diseases and pests of blackcurrant at Orel region in the conditions of extreme drought in 2010 has been detected. Abnormal weather conditions of the summer and the lack of precipitation limited both growth of host plant and disease spreading. At the background of extreme conditions of 2010 the crop phenophases shifted to earlier dates. The awakening of wintering pathogen structures began in the classic dates of the spring, although in summer their biological cycle went off rapidly. Due to the lack of moisture the disease pathogens failed to fully realize their potential of development and spreading. A favorable aspect of the extreme conditions of vegetation period, the reducing of the protective measures against diseases, is to be admitted. Abnormal weather conditions accelerated the pathogen biological cycles and reduced the stock of wintering infection; meanwhile they provoked colonization of the plants by pests. In extremely high air temperature and lasting lack of precipitation the pests number was intensively increasing, exceeding the maliciousness threshold. Due to the above some additional insecticide and acaricide treatments of berry crops were applied. Thus, the vegetation period of 2010 was described as most favorable for the development and spreading of pests and less favorable for disease pathogens.

The paper highlights results of 60 years of apple breeding activity at the All-Russian Research Institute for Fruit Crop Breeding of RAAS (former Orel Zonal Fruit-Berry Experimental Station). Major selection effort has been applied to apple breeding for higher contents of ascorbic acid and P-active substances in fruit. A pattern of the inheritance of biologically active substances in apple fruits is shown. First time in Russia a large-scale selection has taken place for the purpose of developing domestic scab immune apple varieties (Vf ). 20 scab immune varieties have been created and included into the State Register. First time in Russia and in the world a range of triploid apple varieties have been developed through directed diverse chromosome crossings 2x x 4x and 4x x 2x.
