Abstract
Relationships of crossability among biotypes E. caninus from diff erent points of the area, including morphologically
deviating forms, were studied. Ninety one hybrid plants F1 in 42 cross combinations have been grown up. Data about
morphological features and reproductive properties of hybrids in generations F1 and F2 are obtained. Th e estimation
of inheritance of some morphological characters, important in taxonomy, was carried out. It was shown that
E. caninus as the species is formed not only by typical individuals with the limited range of morphological variation,
but also by the big number of the morphotypes mismatching the standard diagnosis of the species. Some deviating
morphotypes are expedient to classify as varieties of E. caninus s. l.
