| Summary: | The paper reveals the steps involved in creating adaptive barley varieties with old parental forms of Wiener,Donetsk650, Krasnoufimsky 95,Omsk13709 and Celinny 5adapted to stressful conditions. It was found that the hybrid fund created with their participation and the breeding lines selected from it have an average advantage of 19.8 % in terms of yield over the standard variety in sowing after non fallow precursors. The promising line E-19-6411 is characterized by a high rate of root length index (1.01) and the percentage of sprouting roots in the test liquid (94.0 %) in the acidic solution as compared to the neutral control sample, which confirms the increased tolerance to the factor. Further field tests of this line showed the yield excess of 13.5 – 38.2 % on acid soil at sowing after different precursors in dry years (2001, 2008 and 2012). At the same time it revealed its high responsiveness and increased soil fertility and adequate moisture supply. The resistance of the studied sample to the appearance of leaf epiphytotics (2002) testified to its enhanced tolerance. As a result of the state variety trials, this line has been included in the State Register on the East Siberian region, as well as in the southern arid regions of theRepublicofTuvaand Khakassia under the varietal name “Olenek” |
