THEORY AND PRACTICE OF CROPS BREEDING AND SEED PRODUCTION
The results of joint work of All-Russian public organization «The Academy of non traditional and rare plants» and the SSI All-Russian research institute of vegetable breeding and seed production of RAAS are presented. The results of two decades of work on the introduction of new, less common and non-traditional plants by scientists from Russia and foreign countries published in fifty volumes of the proceedings of international symposia and conferences and in the collections «The introduction of non6traditional and rare plants and the prospects for their practical use» are reviewed.
AGRARIAN SCIENCE IN THE WORLD
The EUCARPIA European Plant Genetic Resources Conference «Pre6breeding – fishing in the gene pool» was held at the campus of the Swedish University of Agricultural Science (SLU) in Alnarp from 10 to 13 June 2013. This meeting gathered various members of the gene bank community of practice as well as users of the genetic resources from all around the World.
MODERN TRENDS IN VEGETABLE CROPS BREEDING
The analysis of the modern homeland assortment of vegetable crops is given. The donors of the most important traits and the accessions of vegetable and melon crops perspective for breeding from the VIR collection are shown. The short characteristic of the varieties is given.
The main directions and goals of breeding of cucumber, squash, patty pan squash, and pumpkins are shown. The brief characteristic of the varieties of pumpkin crops developed by in the laboratory breeding and seed production of pumpkin crop of VNIISSOK is given.
The method of development of functionally sterile forms of tomato from hybrids derived from crossing between functionally sterile and fertile lines is described. The characteristic of two new lines on the main morphological; biological and economically useful traits and combining ability for yield and fruit weight are shown.
Development of F1 hybrids of tomato for open ground at the moment is one of the main tasks. It can be solved only if there are parent forms with valuable features and properties. As a result of three years of research of tomato hybrid combinations and parental lines in the open field in the non6chernozem zone; the heterosis on major economic traits has been revealed. The character of inheritance of studied traits and the degree of dominance have been determined. The groups of hybrid combinations with high heterosis effect and parental lines that contribute to this effect were identified.
SEED PRODUCTION AND SEED STUDIES OF VEGETABLE CROPS
The features of cultivation and storage of seed collections of the gene pool of vegetable crops have been studied. Elements to improve growing techniques of seeds for dispatch for long term storage are offered. The optimal conditions for storage of vegetable seeds of the gene bank are found. The features of conservation of the collection of vegetative propagated vegetable crops have been analyzed.
The high-temperature stress during 5-20 days has a negative impact on activity of growth of embryo and inhibits the seeds germination of the Umbelliferae crops. The germination of the studied seeds of different species at low temperature contributes to the recovery of the embryo growth; however, growth is less intensive in comparison with the control. All studied Umbelliferae crops showed the differences in seed germination and development of embryos at various tempera6 tures and duration of heat treatment.
The analysis of some methods of pre6treatment of tomato seeds is given. The results of influence of laser irradiation on seeds germination and vigor are described. The positive effect of pre6sowing treatment on tomato yield at cultivation in the open ground in condition of the Low Amur was noticed.
The results of seed production of squash cv. Yakor are given. The agronomic valuable traits; seed productivity and economic efficiency of squash seeds in conditions of peasant farm economy / enterprise were studied.
AGROTECHNICS OF VEGETABLE CROPS
The results of investigation of the effectiveness of humic and bacterial growth regulators at direct sowing of broccoli in conditions of forest6steppe of Ukraine are given.
The effect of microbial growth regulator Mitsefit on sowing qualities of seeds and biometric parameters of pepper seedlings has been studied. The optimal effective concentration 10 ppm for utilization was determined. This concentration has the maximum positive effect on the germination energy; germination; early seedling growth; the rate of occurrence of phenological stages; and biometric parameters of seedlings. Pre6sowing seed soaking in 10 ppm Mitsefit for 30 minutes increases the vigor of seeds of pepper for 4 – 7.5%; the germination of seeds – for 6;5
– 11%; and accelerates the production of pepper seedlings for 3 days.
Under the conditions of Steppe of the Ukraine during 2010-2012 a scheme of planting and plant population of beans played a big role on the formation of a yield of green beans variety Ukrainian Sloboda. The highest yield of cv. Ukrainian Sloboda; 13.5 t / ha; was obtained when the density of planting was 148;1 thousand plants/hectare and the scheme of planting was 45х15.
PLANT PROTECTION
Biological and economic efficiency of the tank mixture herbicide Zenkor Techno and wetting agent Silwet Gold in potato cultivation under the Kaluga region was defined. The absence of significant changes in the efficiency by varying herbicide application rates (1.0 or 0.8 kg / ha) and the volume of the working solution (3006200 kg / ha) was noted.
A workshop devoted to «Problems of bacterial and viral plant diseases in agriculture and development of integrated plant protection» was held at April; 24th 2013 at Russian University of People's Friendship.
MUSHROOM GROWING
The paper presents a commodity output of oyster mushroom growing in the winter and spring time in the basement. The two strains of mushroom; НК635 and R-24; were grown on the different straw substrates. Using straw pea substrate yielded 1;6-2;2 kg/m2 of fruit bodies of the first commodity group of the strain НК-35 and 2;4-2;7 kg/m2 of fruit bodies of the second commodity group of the strain Р-24.
AGRICULTURALMANAGEMENT
The general tendencies of the market development of vegetable crops of protected ground in the agricultural organizations in the Saratov region over the period of 2005-2011 are described in the article. Parameters of productivity; marketability; profitability; structure of manufacture and structure of a commodity output; expenses of work on 1 sq. m and 1 c production on set of the investigated organizations are calculated. The analysis of a condition and tendencies of development of the vegetable6growing agricultural enterprises is studied with use of the basic indicators of descriptive statistics.
VARIETIES OF VEGETABLE CROPS
The new varieties of cauliflower; white and red head cabbages were developed in GNU VSTISP RAAS. The varieties were included in the State register of breeding achievements to 01.01.2013. The patents were received. New varieties have high yield; stable high quality and resistance to biotic and abiotic stress factors.
TECHNOLOGIES AND MECHANIZATION OF AGRICULTURE
The results of the air separator tests on the beet seeds are given.
