Hieracium xgrofae - a rediscovered diploid hybrid from the Ukrainian Carpathians

Popis výsledku v původním jazyce

Diploid hybrid plants (2n = 18) between sexual diploid cytotypes of Hieracium alpinum and H. umbellatum were found in the Ukrainian Eastern Carpathians. They were identified with H. xgrofae WOŁ., originally used for the combination H. decipiens x H. umbellatum var. lactaris. As H. decipiens sensu WOŁ. (non TAUSCH) does not produce viable pollen grains and is most probably a polyploid apomict, it is unlikely to produce diploid hybrid plants with diploid H. umbellatum. Both parent species, Hieracium alpinum and H. umbellatum are also given by WOŁOSZCZAK from the original locality. Thus we conclude that H. xgrofae is result of hybridization between H. alpinum and high mountain form of H. umbellatum. Hybrid plants are morphologically intermediate between the parent species, and moreover resemble closely or they are identical with the experimental hybrids of the same parent combination. Hybrids produce rather high amount of homogeneously-sized pollen grains (values of standard deviation and
