Abstract: Selection of variants tolerant to NaCl and alkaline salt was made from poplar anther callus in vitro culture. The results showed that different poplar species appeared different tolerance to the two screening agents. The calli in differentiation state showed stronger tolerance than that in dedifferentiation state.The differentiated calli of Populus simonii x P.nigra could tolerate 3% NaCl 0.75% alkaline salt. The regenerated plants of variants had transplanted to the soil. In comparing the maps of plantlets a clear difference was found be-tween salt-tolerant variants and controls.

Key words: Poplar, Anther Culture, Salt-tolerant variant
