The present study is aimed at explaining the physical characteristics and bread-making quality of Khorasan wheat (BGR 40365, BGR 12389), einkorn (B2E0417) and emmer (B2000528). Here we will compare the aforementioned grains to both, common wheat (cv. Enola and Sadovo 1) and durum wheat (cv. Progres and Denitza). The physico-chemical characteristics (i.e thousand kernel weight, gluten content and Pelshenke value), are known to differ significantly among the wheat species, however, few studies have examined these characteristics in ancient grains. The highest thousand kernel weight and test weight were observed in BGR 40365. The highest wet gluten content was found in BGR 12389 (34.02%). One variety of einkorn (B2E0417) was determined to be 'gluten free'. Emmer (B2000528) was characterized by high content of wet gluten (30.13%). The best balance between gluten quantity and quality was observed in two varieties of Khorasan wheat (BGR12389, BGR 40365). PC-analysis was applied to group varieties according to their similarity on the basis of ten traits. Three sub-groups could be identified where the first one composed by the hexaploid wheat cultivar Sadovo 1 and cultivar Enola. The second sub-group included cultivar Progres and BGR 40365, while cultivar Denitza, BGR 12389 and B2000528 constituted the heterogeneous third sub-group. [PUBLICATION ABSTRACT]
