摘　　要：为筛选耐盐高产水稻品种,选用25个品种(品系),在辽河三角洲轻、重度盐碱地进行了田间对比试验,结果表明:不同品种在轻、重度盐碱地的产量差异均较大,尤其是在重度盐碱地表现更为明显;同一品种在轻、重度盐碱地的产量也存在较大差异。单位面积颖花量的减少是影响盐碱地水稻产量的主要因素。轻度盐碱地各品种平均单产665.9 kg/667 m^2,盐粳44、花粳1416、桥科951、盐粳933、盐1301、377(紧)比平均单产分别增加了16.3%、9.6%、9.5%、9.1%、8.6%、6.6%;重度盐碱地各品种平均单产298.2 kg/667 m^2,盐粳933、盐1301、盐粳456、花粳1425、盐粳151、花粳1416、花粳1323、377(紧)比平均单产分别增加了31.5%、20.3%、16.0%、14.5%、14.3%、14.1%、13.3%、9.2%。盐粳933、377(紧)在轻、重度盐碱地的产量均较高。25 rice varieties（lines） were planting in mild and strongly salinized land of Liaohe River Delta in order to select salt-tolerant and high-yielding rice varieties.The result indicated there were obvious differences among the different varieties in salinized land especially on strongly salinized land,there was also obvious difference on the same variety in mild and strongly salinized land.The reduce of spikelet＇s per unit area was the major factor to effect the yield.The average yield was 665.9 kg/667 m^2 in mild salinized land,and the yield was increased by 16.3%,9.6%,9.5%,9.1%,8.6% and 6.6% on Yanjing-44,Huajing-1416,Qiaoke-951,Yanjing-933,Yan-1301 and 377（tight type）;The average yield was 298.2 kg/667 m^2 in strongly salinized land,and the yield was increased by 31.5%,20.3%,16.0%,14.5%,14.3%,14.1%,13.3% and 9.2% on Yanjing-933,Yan-1301,Yanjing-456,Huajing-1425,Yanjing-151,Huajing-1416,Huajing-1323 and 377（tight type）.Yanjing-933 and 377（tight type） could get higher yield in mild and strongly salinized land.
