Ecological ability of again registered grades of winter soft wheat

Abstract

The purpose. Study of ecological abllity and response of again registered grades of winter soft wheat on agro-ecological conditions in places of their growing, influence of ecological-adaptive factor upon the level of productivity and implementation of their genetic potential and determination of grades for conforming zones. Methods. Field, laboratory, statistical. Results. lnfluence of environmental factor is studied on develop­ment of adaptabllity, plastic properties and productiv­ity of again registered grades of winter soft wheat. lt Is cJarified that they are characterized by different ecological abllity, manifest deep specific responses to agroecological conditions in places of their growing. lt is fixed that again registered grades of winter soft wheat in different soil-climatic zones, ecological and varying weather environment and at different stressful loads realize differently their natural frultful potential. Concluslons. For solution of problem of ecological adaptabllity and discJosing potential of productivity of grades of winter soft wheat it is necessary to introduce differentiated approach to their disposition in agrocli­matic zones, subzones, micro-zones and geographical points according to demands of selection-and- biological properties of grades.
