Preliminary estimation of freeze-resistance of soybean cultivars developed in Armavir experimental station of VNIIMK

Soybean cultivars developed by the Armavir experimental station of VNIIMK breeding were influenced by negative temperatures under natural environments. Plants cultivated in green houses till the phase of primordial leaves formation - the beginning of the formation of the first trifoliate leaf were moved to a field. Here plants were effected by low positive temperatures. Then, the tested soybeans cultivars, when exposed to negative temperatures (-0.5; -2.5; -2.9 °C) were evaluated for freeze resistance. The cultivar Mechta showed the best results in the experiment.
