DescriptionThe results of development of rice breeding lines, carrying the wide range resistance gene to rice blast disease - Pi-40. For identification of the dominant allele of the gene the DNA - marker analysis was used. With co-dominant DNA markers plants from inbred populations that carry a dominant allele of this gene in the homozygous state were selected

DescriptionThe stage of introduction of plantlets to in vitro culture is an important stage of technology of clonal micropropagation of plants. For the purpose of decrease in a share of the plantlets that were lost from an infection and increase of their regeneration ability, sterilizers and antibiotics, effective and safe for apple rootstocks’ plantlets wee allocated, and also favorable terms of introduction to in vitro culture were allocated. As a result of the conducted researches, we have established that on influence on an nutrient medium and plantlets infection and on growth and development of plants, beneficial effect on apple rootstocks’ plantlets has an antibiotic nystatin of 200 mg/l: the reproduction coefficient on the medium with this antibiotic is equal 4,3, in the same concentration nystatin has the sanifying effect of 60-75% for stocks of SK 2 and MM 106. During researches of sterilizers for apple rootstocks’ plantlets SK 2, SK 3, SK 4, SK 7, MM 106 as an alternative to widely applied highly toxic sterilizer corrosive sublimate (the first class of danger) were picked up effective and safe preparations for sanitation of plantlets from an infection, such as the household preparation "Whiteness" (sodium hypochlorite) in cultivation 1:2, low-dangerous substance of the fourth class of danger (a share of viable plantlets of 75,5% from initially introduced), and also fosfopag, a preparation of the fourth class of danger (a share of viable plantlets of 65% from initially introduced). The favorable term for a meristem of apple rootstocks’ plantlets’ introduction to in vitro culture are phases of buds’ burgeoning (March) and the intensive growth of shoots (May – June)

DescriptionThe results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total content of this element in the 0-20 cm 21-40 cm soil layer by 69.4 and 66.5% of silicate and by 30.6% and 33.5% free group of compounds of iron. The applied system of fertilizer crop rotation helps reduce the silicate and increase of free group its compounds. In leached black soil a group of desilicated iron in the 0-20 cm layer 24.8 % presents crystallizability and to 75.2% amorphous compounds, 21-40 cm layer, respectively, 26.2 and 73,8 %. Under the influence of fertilizers we have noticed increasing of amorphous and reducing the number of cristallizing forms of the compounds of this element the soil. The number of different groups and forms of iron compounds in leached black soil with systematic use of fertilizers in crop rotation is determined not by the size of introducing this element as impurities, and processes such as the alienation of iron with additional derived products, increase its mobility in the soil due to a shift in the reaction of the soil solution, changes in fractional-group composition of humus. Diagnostic criteria state of iron in the soil are leached quantitative ratio of the content of the various groups and forms of the compounds of this element

DescriptionRemineralization of leached black soil was carried out by making such rocks as loess-like loam, shell limestone, apatite phosphogypsum. It was revealed, that the introduction of species did not change substantially the content of boron during the growing season. The manganese content in relation to the control increased by 13-15%, 25-30% for copper, zinc, 35-45%, 25-30% cobalt, and molybdenum in 2-3 times, and especially when combined application of rock. Seasonal dynamics was expressed, but does not give definite pattern
