Abstract
There were evaluated the differences between the line and grade «Obriy» created on its base disomno-supplemented line «O27-2», which was bearing the alien signs of resistance to leaf rust and the leaf trichomes on amfiploida Elymus fertile. It is mainly determined by the negative impact of alien chromosomes on the characteristics of the main spike (length, amount of spikelets and grains, grain weight), plant height, number and weight grains with the regrowth. But signs: productive tillering, the length of the main spike, amount of spikelets in the main spike, grain mass from the main spike, with the regrowth and, in general, with the plants – some is influence substantially modified by the conditions of the year. Supplemented line the higher was characterized by thousand kernel weight, in accordance with a recurrent form. Specified chromosome significantly increases plant resistance to leaf rust, but has no effect on the response of plants to be affected with powdery mildew, yellow and stem rust, septoria blight, barley yellow dwarf virus in which both lines showed susceptibility.
