One of the main objectives of bread wheat breeding in south of Ukraine is the creation of varieties resistant to most diseases that distributed here (Blumeria graminis, Puccinia triticina). It is the interaction of several genetic systems in one organism. They must be stabilized there. Cultivation of these varieties enables ecologically clean products with minimum using of fungicides or without them. According to that, the purpose of our study is to determine the value gene Lr34, translocation 1BL/1RS and wheat variety type from West Europe in germplasm from south of Ukraine. Use these systems of disease resistance combined with other valuable features in the hybridization will build resistance to disease with different monogenic and polygenic systems.

Material and methods. Research material was:

a) varieties west European type from Plant Breeding and Genetics Institute with gene locus Lr34 (Dalnyts’ka, Yednist’, Lytanivka, Hoduval’nytsia) and wheat-rye translocation 1BL/1RS (L49310, L49410, L49810, L65910);

b) breeding lines west European type from Odessa without gene locus Lr34 and wheat-rye translocation 1BL/1RS (L11807, L13208, L13308, L13509);

c) variety Antonivka without gene locus Lr34 and 1BL/1RS, but it has optimal resistance to Blumeria graminis and Puccinia triticina for conditions in the south of Ukraine.

Research was conducted during 2012-2014 period at the Plant Breeding and Genetics Institute. Cropping system - fallow before sowing. The soil was fertilized by N32 P32 K32. Plot - 25m . Quadruple repetition. Herbicide: tribenuron-methyl 750 g/kg - 0.015 kg/ha. Diseases were evaluated by 1-9 scale (1-susceptible, 5-moderate, 9-resistant) in the artificial infection.
