DescriptionThe value of the initial material for selection for heterosis is primarily defined by the combining ability in respect to the main economically valuable characteristics. Combining ability with respect to “grain productivity” has been studied among fourteen selfpollinated lines of maize of early ripening and three testers in the system of hybrid combinations. We have proved that weather conditions have an influence on the variability of the estimates of the combining ability. We have identified the new self-pollinated lines of maize SP 165 and SP 175, which are characterized by invariably high evaluations in the effects of GCA (gi) in different years. The new self-pollinated line SP 167 has got high variants of SCA (δ2si). The new lines SP 161, SP 163, SP 167 and SP 174 have been characterized by the variability of the evaluations in the effects of GCA. They are related to the first or second rank in respect of GCA, depending on the year of the conducted evaluation. These are SP 163, SP 164, SP 170, SP 171 and SP 173 that have differed by their variability of the variants of SCA (from the low variants to the high ones). The highly productive testcross hybrids: Madonna M × SP 165 (4.88 t / ha), Madonna M × SP 171 (4.85 t / ha), Madonna M × SP 167 (4.80 t / ha), T 7M × SP 165 (4.78 t / ha) have been obtained based on the self-pollinated lines having invariably high figures of GCA and SCA

DescriptionThe researchers of the institute are studying adaptive power of 17 varieties and 6 lines of winter wheat sown after peas using various methods of assessment of their adaptive properties. During the years of study (2012-2014) we found out that environmental conditions which account for 78% have the greatest effect on the trait ‘grain productivity’ in the formation of the yield. The share of genes accounts for 9,7%, the specific correlation ‘geno type x environment’ accounts for 10% which allow calculating adaptive properties. It has been defined that productivity of winter soft wheat changed a lot due to growing conditions and characteristics of varieties. The productivity ranged from 38,7 c/ha (‘Garant’ in 2014) to 76,5 c/ha 9’Lilit’ in 2013). The study found out that the varieties ‘Stanichnaya’, ‘Asket’ and ‘Lilit’ possess the highest response to cultivation with bi=1,15; bi=1,18 and bi=1,25 respectively. The varieties ‘Lilit’, ‘Krasa Dona’, the lines ‘430/07’, ‘260/09’ and 771/09’ possess a high adaptive ability and productivity with 111%, 105%, 108%, 105% and 106% respectively. The study of adaptive properties of winter soft wheat varieties gives an opportunity to distinguish adaptive, stress tolerant varieties with plasticity according to the primary structural elements which form productivity. The varieties ‘Asket’ and ‘Lidiya’ are characterized with high response to cultivation in different environmental conditions. The varieties ‘Lidiya’ and ‘Kapitan’ belong to adaptive cultivars. The varieties ‘Kapitan’, ‘Krasa Dona’ and the line ‘234/07’ are stress tolerant according to the trait ‘grain productivity’; the varieties ‘Kapitan’, ‘Krasa Dona’, ‘Lilit’ and the line ‘771/09’ are stress tolerant according to the trait ‘number of seeds per a ear’; the varieties ‘Lilit’, ‘Krasa Dona’ and the line ‘771/09’ are stress tolerant according to the trait ‘weight of seeds per a ear’

DescriptionCombining ability with respect to “grain productivity” has been studied among thirty eight self-pollinated lines of maize of mid-early and early maturing in the system of hybrid combinations. The lines with high general (GCA) and specific (SCA) combinative ability have been hybridized. New high heterotic hybrids have been developed on the basis of lines with high GCA and SCA

Description
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region

TRACE ELEMENTS AND HEAVY METALS IN WATER AND BOTTOM SEDIMENTS DRAINAGE NETWORK DAGHESTAN
06.00.00 Agricultural sciences
DescriptionIn the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher

CREATION OF THE INDICATIVE AND GENETIC COLLECTION OF THE LARGE-MASS GRAIN OF THE GRAIN SORGHUM
06.00.00 Agricultural sciences
DescriptionThe 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
