The author estimated 173 varieties of soy on corn productivity in different soil-climatic conditions, watering and waterless phones. The greater promising forms were isolated and determinant of seed mass from plant in connection with cultivation condtions has been shown.Correlated interrelations between corn productivity and other elements of harvest structure have been revealed. On the basis of regressive analysis and the most significant homeostasis parameters were analysed the reactions of each form on the variated environmental conditions. The new ecologically plastic soy varieties Volgogradka 1 and Volzhana with a high productivity were obtained.
