摘　　要：对经过连续3a的田间耐盐性鉴定筛选出的2份小麦耐盐性种质在4个不同含盐量梯度的田间鉴定,结果表明:2份小麦耐盐种质在农艺性状和产量水平上对盐胁迫有较高的耐盐性,在4个不同含盐量梯度上种植的产量均高于对照品种宁春4号,在含盐量0.3%～0.5%的盐渍土壤上种植有较大价值。Through threeyears field experiment, the three differe n t salttolerance wheat materials have been evaluated in four different soil sal t levels. Two of them (99sw10, 99sw12) were shown higher in salttol er ance and better in agronomic charaters and productivity than CK (Yongliang 4). Therefore, they could be extended in the fields with salt soil.
