In recent years, due to the increasing aridity there was
an increase in the frequency of epiphytoties leaf disease
of barley. Therefore, we can see now how greatly
increased the need for the creation of resistant grades.
Introduction of the selection marker will significantly
speed up the breeding process for resistance to
pathogens. Employees of the All-Russian Institute of
Plant Protection recommended three genes - Rpt 1b,
Rpt 5, Rpt 6 to control the resistance to the pathogen
Pyrenophora teres for use in breeding programs in the
North Caucasus. Rpt 5 gene is one of the most efficient
one, because it determines the resistance to the eight
isolates of the fungus Pyrenophora teres of different
origin. In 2011, Australian scientists have discovered
microsatellite markers called Bmag0173 and HVM74,
closely linked to the gene Rpt5, which are used very
effectively in order to marker-assisted selection of
resistant grades in Australia and Canada. Due to the
urgency of creating new genotypes carrying resistance
genes to net blotch, that would be effective in the
Southern Federal Region, the staff of All-Russian
Scientific-research institute of Grain Crops after I.G.
Kalinenko and the All-Russian Research Institute of
Plant after N.I. Vavilov has developed a practical
strategy for the use of molecular techniques to create
barley grades resistant to this pathogen, which is being
successfully implemented
In the article, the results of studying of laws of inheritance of quantitative signs of winter barley are presented
The results of the analysis of inheritance of a sign «weight of 1000 seeds» in F1 winter barley are resulted in this article. Examples of various types of inheritance at double-row, correct six-row and wrong (tetrahedral) hybrids are resulted
In the article, the results of the genetic analysis of inhe-ritance of hybrids F2 are presented. Degree and fre-quency of transgression are calculated
