Abstract: A new poplar elite variety of Populus simonii×P.euphratica ‘Liaohu 1’, with characteristics of fast-growing and salt-alkali tolerance, is a heterozygote derived from natural pollination of F1 of hybrids of P.simonii×P.euphratica, and it is female. The 18-years-old ‘Liaohu 1’ trees had the average tree height of 11.17 m, DBH of 17.26 cm and individual volume of 0.132 1 m3 grown in saline-alkali land with salinity 0.25%-0.4% and pH 9.0. Compared with P.×xiaozuanica ‘poplar’, the volume growth increased 140.0%. The ‘Liaohu 1’ has characteristics of fast-growing, salt-alkali tolerance, easy reproduction and cold-resistant.
