EVALUATION OF THE COMBINATIONAL ABILITY OF THE PARENT FORMS OF APPLE TREES ON RESISTANCE TO SOIL SALINITY

Abstract

Summary. Evaluation of apple hybrid seedlings obtained from topcross-crosses for resistance to salinity was carried out. The in fl uence of both additive and non-additive gene interactions on the for-mation of resistance with some predominance of the lasts was revealed. Donors and hybrid combina-tions with high combining ability, promising for practical use in breeding for resistance to salinization were identi fi ed. Hybrid seedlings as sources of high and stable resistance were singled
