Abstract: By use of anther culture technique,salt-tolcrantc variants of winter wheat were screened at the cell level by adding quantitative NaCl into the medium C₁₇.About 143331 anther of F1 were cultured on the medium by direct screening and incrcasing salinity screening method.The results proved that the later was a more effective measure for obtaining salt tolerante variants.Green differentiation frequencies on C₁₇+0.1%,NaCl-(callus)-C₁₇+0.3% NaCl and C₁₇+0.1 % NaCl-callus-C₁₇+0.5% NaCl increased 5.06 and 15.0 times respectively,compared with direct screening method,by calculating the number of anthers cultured.Pollen plants differentiated on higher salinity medium C₁₇(added 0.3% and 0.5% NaCl)and their progeny(H2 H1)have higher salt-tolerance.They could develop normally or basically normally in the soil containing 0.4% salimity.
