Wheatgrass variability (Agropyron, sect. Elytrigia) in a native collection from Transylvania. II. Agropyron repens (L.) P. Beauv (in English)

In continuation of former studies regarding wheatgrass variability (Agropyron Gaertn. Sect. Elytrigia) carried out on 89 different populations collected along a transect in Transylvania (Not. Bot. Hort. Agrobot. Cluj,1979, X. 89-99) results regarding 31 A. repens (L.) P. Beauv populations are presented in this paper. Average values per population for open pollination fertility (OPF) varied betweeen 0.0-40.0%; spike length: 59-196 mm; spikelet length: 8.8-17.0 mm; number of caryopses per spike: 0.0-40 etc. The results may contribute to the explanation of some microevolutionary processes and differential spreading patterns found in Elytrigia section.
