EVALUATION OF TURF QUALITY FOR COOL SEASON SPECIES AND CULTIVARS
06.00.00 Agricultural sciences
DescriptionSeries of field and laboratory studies were conducted from 2011 to 2012 in Russian State Agrarian University to evaluate a collection of 4 turf grass species and 15 cultivars for quality, summer density, ground cover and germination percentage. During 2 experimental seasons the plants have been growing with the extensive treatments. Turf quality was evaluated visually using a 1 to 9 scale. The two-way analysis of variance was used to identify genotype’s effects on density, ground cover and germination percentage

DescriptionThe article reflects the results of experimental studies in heterosis breeding of corn. We defined the common (CCA) and specific (SCA) combining ability of the new material. We also obtained the valuable inbreeding lines and testers of corn, created based on these new hybrids. The final step was the evaluation of hybrids and calculation of economic efficiency of their implementation. As a result of the work, it was allocated the three hybrid combinations of corn and suggested to examine them in strain testing

ASSESSMENT OF THE NEW SOURSE MATERIAL FOR BREEDING EARLY AND AVERAGE MAIZE HIBRIDS
06.00.00 Agricultural sciences
DescriptionThe article presents the result of correlation analysis of harvest structural elements. They have been analyzed for their effect on the biological yield inbred lines. The distribution of inbred lines in terms of manifestation of each trait separately was made. The final step was the evaluation of hybrids and calculation of economic efficiency of their implementation. As a result of the work, three hybrid combinations of corn were selected, and studying in further strain testing was suggested

SUNFLOWER LOW TEMTERATURE GROWTH RATE EVALUATION CONCERNING BREEDING FOR COLD RESISTANCE
06.00.00 Agricultural sciences
DescriptionOne of the prospect directions in new sunflower hybrid development is cold resistance breeding in the emergency stage. Sunflower hybrids with uniform emergency and high rate growth under the low temperature conditions could allow to introduce sunflower in the new regions of our country and so to increase sunflower acreage. The aim of our work was to screen all sunflower available samples for growth rate under the low temperature and to select the best lines and initial material for future breeding. 140 sunflower lines of VNIIMK breeding and hybrid populations on their base were used as a material. Seeds of every sample were incubated during the 10 days in the thermostat under 100 С. Seed germination was evaluated for the each sample along with the seedling size. As a result the most prospective samples were selected for the future breeding work. On the second stage of the experiment one selected population was evaluated on the Breeding station of Vavilov’s AllRussian Research Institute of Plant Industry in the city of Pushkin (Leningrad region). Seeds from the best plants were obtained in this place and will be used for the new lines development. So the effectiveness of selection of sunflower samples for growth rate under the low temperature was verified and this method could be used to introduce sunflower in the new regions of our country with more severe climatic conditions

DescriptionA comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
