THE USE OF MOLECULAR BREEDING METHODS RESISTANCE TO NET BLOTCH OF BARLEY (REVIEW)
06.00.00 Agricultural sciences
Description
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
