Descriptif
The main aims of this thesis relate to : ¾ Tests of the feasibility of methods (based on physiological characteristics) for the selection of drought tolerance in winter wheat ¾ Evaluation of the selection work by these methods in a wheat-breeding program. ¾ Clarification of the roles of the major yield components of some old and new winter wheat genotypes originating in Szeged as concerns productivity and abiotic stress tolerance ¾ Determination of the correlation between the results of field and laboratory tests of drought tolerance,and the field data based on the results of multilocation field trials. ¾ Utiliziation of the selected testing methods in a winter wheat breeding program to improve drought resistance and general adaptability.
