A middle-early maturing cold-resistant soybean cultivar Iney

The middle-early maturing soybean cultivar Iney was obtained as a result of individual selection in F4 from the hybrid combination Belogorskaya x Fora on differentiating backgrounds for traits of reduced response to day length, cold and frost resistance, drought tolerance. Additionally, we evaluated the degree of cold resistance of the parental material by a cryo-sedimentation method. According to the results of the tests of 2017-2018, the cultivar Iney exceeded the standard variety Slavia on yield by 0.20 t per ha. The height of plants at the latitude of Krasnodar (45°) is 95-108 cm. The new soybean cultivar Iney is highly resistant to lowered air and soil temperatures and differed with high yields under dry conditions. This allows it to be cultivated as a main crop in the North Caucasian, Central Chernozem, Lower Volga and Far Eastern regions of the Russian Federation, as well as in the Republics of Kazakhstan, Uzbekistan and Kyrgyzstan at geographic latitudes from 40 to 50°.
