Selected items of wheat variation -From palaeobotany to molecular biology

摘要

The usefulness of data on ecotypes of wheat as well as of information about distribution of genes of hybrid necrosis for an interpretation of some questionable detections of fossil materials is emphasized. Variablility of contemporary wheats is illustrated by means of morphology of lodicules, anatomical structure of caryopsis, morphology of embryo and features of epidermis of inflorescence bracts.
