New varieties of winter durum wheat selected by methods of complex crossing varieties of winter durum wheat of different ecological-geography region and their mutants differ with quality of grain adaptability to econiche. Value of chemical mutants in selection of winter durum wheat on adaptability and quality of grain is discussed
The inheritance of the “mass of 1000 grains” sign in the hybrids F1 and F2 was studied. Differences in the parental forms with 1-5 pairs of genes are revealed. The sources and the donors of the large-mass of grain are pointed, the indicative and genetic collections of the large-mass of grain forms of the grain sorghum are created
PHOTOSYNTHETIC ACTIVITY OF THE GRASS MIXTURE IN THE CONDITIONS OF THE RECULTIVATED ASH DISPOSAL AREA
The results of multi-years field study of the research of photosynthetic activity of Hungarian sainfoin + coach grass + awnless brome grass mixture in the conditions of the second recultivated section of ash disposal area of the Novocherkassk SDPP are reported
The crop productivity of peach varieties in different fruit zones of Krasnodar region was studied. The economic analysis of effectiveness of their growing was done. The practical recommendations on peach-tree gardens making were given by the results of five-year researches
Researches of improving of effectiveness of ways of fruit-tree stock rooting, stone cultivars of home and foreign selection were carried out at Krymsk experimental selection station. Reliable and effectiveness ways of reproduction of green and senescence cuttings were offered based on the results of this work. Stocks of stone cultivars for given systems of reproduction were allocated
The influence of peach-tree stocks on growth and development of different varieties in the conditions of Krymsk ESS (Krymsk) was studied. There were assessed the different parameters of growth and development of fruit trees. The most effective combinations of this culture were selected by the complex of economic signs
Researches on assessment of peach-tree stocks stability to soil pathogens (nematodes, fungi and bacterial diseases) and to the excess of lime and moisture as well were carried out in the conditions of scientific-industrial enterprises of Agromillora Cotalana (Spain). Adaptation level of studied stocks to marked stressors was determined upon the results of this work. The steadiest to them are allocated. Various parameters of grades of a peach in these conditions are estimated
The analysis of qualitative indicators of Don selected soybean varieties aimed to determine a possibility of their usage in processing industry is carried out. An evaluation of chemical and organic leptical indicators of soybean seed quality and physical properties is made. Possible directions of Don selected soybean varieties usage in processing industry are determined
Value of new linear sorts allocated by the method of analytical selection from sort Stepnaya 7 in increase of adaptability of winter soft wheat is discussed. The new linear sorts: Line 15, AMMA, Line 21, Line 11, Line 26, Line 29, Line 36, Line 37 revealed combination of stability to brown and yellow rusts. Productive varieties with high quality of grain: Magnificent, Line 12, Line 38 have shown stability to a brown rust and poorly affected by other mushroom diseases
Using two microsatellite loci (HaSSR1, HaSSR3), the PCR analysis of the bollworm Krasnodar population was conducted. Molecular-genetic analysis (SSR-PCR) of different geographic codling moth populations by three microsatellite loci Ср1.63; Ср2.39 и Ср2.157 was conducted also. Based on the assessment of the frequencies of occurrence of DNA markers, the molecular-genetic structure was described and genetic diversity in the pest populations was estimated
