| Abstract: | Summary Research on the morphology, geography and infraspecific taxonomics of Triticum dicoccoides Körn. performed during the 80 years since its rediscovery by Aaronsohn is reviewed. T. dicoccoides is a vluable genetic resource for the improvement of cultivated wheat. Its intraspecific structure is, however, not known sufficiently. It is evident that T. dicoccoides is subdivided into two morphologically and geographically distinct forms. The intepretations of these forms by various authors are diverse. There is also no consensus concerning their geographical within the general range of T. dicoccoides. It is necessary to carry out a detailed morphological study in order to define their taxonomical rank and specify their ranges. It would be expedient to perform comparative genetic, biochemical and agronomic investigations of the two T. dicoccoides infraspecific types. |
