In Russia the first allotriploid grey poplar has been selected in the Voronezh region. It is a female plant distinguished by high productivity and stability. Cytoembryological studies of allotriploid and diploid grey poplar have been conducted to determine the low percentage of seed binding (sterility). Anomalies in the formation of macrogametophyte have been observed in the triploid seedbuds. 70% of the 144 cells analyzed in triploid poplar had pathologies in the embryo sac, which leads to the formation of sterile seedbuds. Anomalies of macrogametophyte prove hybrid, triploid nature of this form of poplar. The selected poplar is propagated only vegetatively to preserve its hereditary traits.
