aref2 The influence of color of leaves on the resistant of wheat varieties to drought and their productivity in the Orenburg steppes of the Urals is revealed. The investigations were carried out using the prospective recognized varieties of spring wheat of Volga steppe ecotypes of Saratov selection - Albidum 188, L - 503, Prokhorovka, Saratovskaya 42 and 66; of Orenburg selection - Varyag, Logachevka, Orenburgskaya 13 and Uchitel; hard spring wheat of Volga steppe ecotypes of Samara selection - Bezenchukskaya 182, 200 and Bezenchukskiy yantar; of Orenburg selection - Orenburgskaya 10 and 21. The correlation and regression analysis method was used during the mathematical processing of experimental data. It is founded that with an increase the intensity of leaves color, there is an increasing of drought and crop yield. The prospective varieties of bread and durum wheat for the selection is allocated on the peculiarities of high drought resistance, the dependence of the yield on the level of drought is shown in the article. The obtained results can be used in the selection of parental forms for the breeding and selection of resistant wheat hybrids in the steppe zone of the Southern Urals.
