The results of estimation of growth and development parameters, SSR analysis, electron microscopic examination of the surface of pollen and seeds, biochemical composition (ascorbic acid, carotenoids, carotenes, macro- and microelements content in the stem part of plant) of 8 Chinese broccoli, Brassica oleracea var. alboglabra samples grown in the unheated greenhouse of the Central Siberian Botanical Garden SB RAS, Novosibirsk (54°49′33″ N, 83°06′34″ E) and phy- totron of N. I. Vavilov Institute of Plant Genetic Resources (VIR) have been presented. Through the study, the large surface cellularity of B.oleracea var. alboglabra (cv. “Siji Xianggu jie lan” [“SX”]) seeds was similar with seed coat surface of B.oleraceae var. capitata f. alba cv. "Slava". A scanning electron microscopic study of Chinese broccoli pollen (cv. “SX”) revealed the formation of colpate pollen with ellipsoidal shape with a size of 32.9 ± 0.76 x 17.8 ± 0.42 μm, characterized by foveolate ornamentation with a length-to-diameter ratio – 1.85.The duration of the period from emergence stage to thickening of a stalk and flower-bud formation of cv. “SX” continued for 49-54 days. Сlose correlation was established between the largest diameter of the stem and the length of the leaf petiole (r=0,87, p < 0,001) and between the length of the leaf petiole and the weight of the stem (r=0,77, p < 0,001). As a result of molecular screening of Chinese broccoli using 5 SSR markers (Na10D09, Ol12F02, Ra2E12, BC 7 и BC 65) the greatest polymorphism was in the test with the BC 7 marker - five alleles from 160 to 295 bp in size. In the “SX” variety single flowering (10%) occurred on 59 ... 63 day and mass flowering (75%) – on 65 ... 68 day. The stem part of B. oleracea var. alboglabra is a fairly good source of vitamin C, accumulating as much as 32-46 mg/100 g, and also increased concentration of K, Ca, Mg and Cu. At the end of the season the fruits, together with the phytomass of stems are well-seasoned for 3-4 weeks forming viable seeds with germination above 85% corresponding to the Russian state standard (GOST 32592-2013) for white cabbage seeds.

Pepper (Capsicum annuum L.) is an economically significant nightshade culture in many countries, including Transnistria. On the basis of the State Institution "Transnistrian Institute of Agriculture" in conditions of open ground on a long-term provocative background of monoculture of nightshade, the study of various diseases of sweet pepper is conducted, the allocation of resistant plants for further selection work on the creation of specialized varieties and F1 hybrids with high genetic potential and resistant to stressful environmental factors. In 2016-2017 the selection material for selection of sweet pepper for resistance to major diseases (verticillosis, yellow wilting, or phytoplasmosis and viral pathogens) was studied. The best selection samples were selected for the complex of features. According to the total yield, Positron variety was significantly superior to the standard by 13% and L-70 sample by 19%. A complex phytopathological evaluation showed that the L-70 sample was very poorly affected by verticillium fading, and yellow fading and viral diseases - to a weak degree. The Positron variety was characterized by a mild disease defeat. The degree of development of verticillosis in general in the nursery was weak and varied from 6,8 (L175) to 11,4% (L-144), the development of yellow wilting – from weak to medium – 22,2-41,5%, and the damage caused by virosis varied within the limits of 16,2-33,7%. The most harmful were phytoplasmic diseases, which manifested themselves mainly in the form of yellow wilting and to a lesser extent – a typical stalk caused by phytoplasm PhLO. Thus, in the competitive test, a sample L-70 with a high yield of commercial fruits and a minimal disease affection in a complex phytopathological assessment was identified, as well as a Positron variety with a high early and overall yield and a low disease burden. The best indicators of the biochemical composition of fruits, as close as possible to the requirements of the canning industry, were samples of L-175, L-134, L-144 and Positron variety.

Qualitative and quantitative evaluation of tomatoes carote-noid composition is considered to be the basis of tomato selection. Among known methods of identification and carotenoid content determination thing layer chromatography (TLC) is characterized by inexpensive, quick and availab-le method of analysis. Comparison of individual tomato carotenoid content data obtained using wellknown empirical formulas and based of TLC separation on chromatoraphic paper was achieved. Empirical formulas for the determination of lycopene and beta-carotene concentrations were shown to give high variations in beta-carotene content and decreased values of total carotenoids concentration values. Developed conditions of chromatographic separation and identification of selected carotenoids are based on different polarity of individual pigments and specific absorption spectra of the latter. Method of thin layer chromatography may serve as a quick and effective method for quality evaluation of tomato fruit of different color and determination of beta-carotene, ζ-carotene, neurosporene, lycopene and lutein content.

The result of collaboration work between Siberian Research Institute of Plant Cultivation and Breeding, the branch of The Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences (ICG SB RAS) and the company OOO Geterozisnaya Selectia on ecological trial and assessment of economically valuable traits were obtained in promising radish accessions. The data on influence of sowing terms on yielding ability, formation of flower bearing stalks was analyzed and morphological descriptions for radish accessions were given. It was shown that the development of marketable radish roots can be possible in condition of long lasting light period. When sowing in the second decade of June less number of flower stalks formed on the plants than on the control plants of ‘Raniy Krasniy’. The sowing in the first decade of August did not give any plants with flower stalks in accessions 17-12 and 17-13. The highest yield at first sowing term was observed in accession 17-12 at second sowing term in accession 17-13, 5.6 and 6.1 kg/m2 respectively. The accession 17-12 was distinguished by root weight, 19.2 g. The highest dry matter content (5.31%) was observed in accession 17-11; the highest total sugar content (2.18%) was in accession 17-12; the highest ascorbic acid content (25.1 mg %) was in accession 17-13. The comparative analysis of data on summer and autumn sowing terms showed that when sowing in summer time, at long lasting light period the radish accessions were characterized by the more number of plants with flower stalks; more developed leaf apparatus; larger roots and enriched biochemical composition as compared with the accessions sown in autumn time. All accessions tested belonged to early-maturing group, where the root formation takes for 22-25 days. For economically valuable traits the accessions 17-12 and 17-13 were selected out.

The important goal of breeding program is to achieve the heterosis effect and develop the appropriate breeding lines to be used for crossing. The cultivation of the variety or breeding line for a long time and selection process under the same environmental factors lead to decrease of livability and productivity of the variety or breeding line. The intra-varietal and intra-line crossing is the method that enables to improve the genetic basis of the existing breeding accessions, when increasing the recombination ability, particular-ly among valuable and rare characteristics. The accessions of sweet pepper of different ecological origin: local varieties ‘Aeneas’, ‘Ivanhoe’ (Ukraine), ‘Sladkiy’ (Italy), breeding line ‘n 138d’ (Russia) were taken to study the influence of intra-varietal crossing on recovery of combining ability in breeding lines. The progeny produced from intra-varietal crossing has been assessed for the fruit number, average fruit weight, yielding ability and marketability, and then consequently compared with control accession. As results showed the yielding ability had increased by 2.3-25.7%, depending on genotype, while the fruit weight had increased by 2-11%. Phenological observation showed that there is no significant difference at the phase of growing and development between control plants and plants produced through intra-varietal crossing. The detailed progeny assessment has revealed the different effect of adaptive ability among different plants when the plants crossing within the same accession. This enables to select the best accessions to be used in further heterosis breeding pro-gram.

The thematic core facilities plan, CCU of Orel state agrarian university "Genetic resources of plants and their use" for a joint program with Shatilovskay of Institute of leguminous and cereal crops, of field and vegetation experiments on the study of specific features of manifestation of the activity of transpiration leaves of soybean are achieved. The object of the study were 10 varieties of soybeans that were grown on plots of 15 m2 in four replications. Seeding was carried out breeding seeder calculated 600 thousand of viable seeds per hectare. the way the plots were allocated systematically with offset. The care of crops was carried out in accordance with the recommended regional events. It was demonstrated that leaf transpiration activity of the culture increases sharply in the transition of plants to the generative period of development, reaching a maximum in the phase of mass fruit formation, when the most active growth and, consequently, the demand for assimilate. The intensity of transpiration of leaves during this period of plant development was by 8.22 mmol H2O/m2c. The highest transpiration activity was typical for the upper leaves located in the generative sphere of plants, the lowest - activity was fount for the lowerst leaves. On the 5th node from the bottom, its value was 2.2 times lower compared to the assimilating leaves at the top of the plants (3-4 knots top). Thus, the most intensive evaporation of the water by leaves are held from 9:00 to 13:00 hours Moscow time. The intensity of transpiration in this period amounted to an average of 5.42 mmol H2O/m2c, which was 19.9% higher than in the morning (from 7:00 to 8:00) and 42.3% in the afternoon (from 15:00 to 17:00).
