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.
