| description | The article considers the parameters of ecologic adaptability and stability of the varieties and lines of soft winter wheat in the conditions of provocative background (“zasushnik”). It has been studied stress tolerance and genetic flexibility of the trait. During the research the varieties ‘Don 93’, ‘Izyuminka’ and ‘Rostovchanka 7’ showed a low co-efficient of variation with СV=39,3%, CV=39,7% and CV=39,8% respectively. The coefficient of line regression (bi) has been also determined. The co-efficient of all varieties, except ‘Don 93’ is more than 1; it shows that productivity of main set of varieties increases under the influence of improvement of growing conditions. The variety ‘Don 93’ is more adapted to various environmental conditions (bi=1). The varieties ‘Don 93’, ‘Tanais’, ‘Marafon’, ‘Spartak’ and ‘Rostovchanka 7’ showed their productive ecologic stability. The varieties ‘Don 93’ and ‘Rostovchanka 7’ showed their high stress resistance. The varieties ‘Marafon’, ‘Izyuminka’ and ‘Rostovchanka 7’ showed their genetic flexibility. |
