INTERRELATIONS BETWEEN PRODUCTIVITY AND ELEMENTS OF ITS STRUCTURE AT GRADES OF SOFT WINTER WHEAT
DescriptionCorrelation interrelations of some morpho¬logical signs of winter wheat and their influ¬ence on productivity are established. Positive correlation communication of efficiency with weight of grain with an ear (r=0,70) is revealed

Description
The search of resistance sources to the wheat stem rust pathogen among wheat collection material, its rare species and Aegilops (goat grass) was conducted. The samples resistant to the pathogen were detected. They have been studied on the artificial infectious background for three years and they are recommended for use in selection

Description
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24. The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance

PRODUCTIVITY OF LEGUME-MEADOW GRASS MIXTURES IN CONNECTION WITH COENOTIC INTERACTION OF PLANTS
06.00.00 Agricultural sciences
DescriptionThe rational method of efficient control of agroecosys-tem in arid areas of Northern Caucasus, based on ex-pansion of perennial grass sowing is offered. The intro-duction in phytocoenosis structure of multicomponent grass mixtures with meadow and leguminous grasses provides a high recoupment of antropogenous expenses

ROLE OF SOIL PROCESSING IN PRESERVATION OF SOIL FERTILITY ON POTENTIALLY EROSAL SLOPES
06.00.00 Agricultural sciences
DescriptionIn the article results of researches of influence of ways of soil processing on its structurally-modular composition and humus maintenance under a winter wheat in the conditions of potentially erosal slopes are presented. At chizel processing, the quantity of agronomical valuable units increases. High positive dependence between accumulation of humus and quantity of oozy fraction is revealed

DescriptionValue 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
