采用蒸渗计砾石培养技术研究了16个小麦基因型的耐盐性。将一周龄的小麦幼苗暴露于由NaCl产生的盐度。试验设对照组（1.5dSm-1）、低盐组（6.0dSm-1）、中盐组（9.0dSm-1）和高盐组（12.0dSm-1），重复3次。根据需要使用1/4 Hoagland营养液进行灌溉。定期监测每个处理的盐度水平，并在整个生长期内保持。在作物成熟时记录产量和产量构成。在不同生长变量降低小于50%的基础上，发现5个基因型，即LU-26 s，HT-45，ESW-9525，V-8319，Sarsabz耐受，而Bhittai。Marvi、Chakwal-86、DS-17、Sussi（SD-66）、Zardana为中等耐性，SD 1200/51、Khirman、V-7012为中等敏感，RWM-9313、SH-43为敏感。耐盐小麦基因型成功地维持了低钠和高钾吸收以及高K/Na比。
Salt tolerance of sixteen wheat genotypes was studied using gravel culture technique in lysimeters. One week old wheat seedlings were exposed to salinity created with NaCl. Four salinity levels, i.e. control (1.5 dS m -1 ), low saline (6.0 dS m -1 ), medium saline (9.0 dS m -1 ) and highly saline (12.0 dS m -1 ) and three replications were maintained. Irrigation was applied as and when required with 1/4 th Hoagland nutrient solution of respective concentrations. Salinity level of each treatment was regularly monitored and maintained through out the growing period. Yield and yield components were recorded at the time of crop maturity. On the basis of less than 50% reduction in different growth variables, five genotypes viz. LU-26s, HT-45, ESW-9525, V-8319, Sarsabz were found tolerant, whereas Bhittai. Marvi, Chakwal-86, DS-17, Sussi (SD-66), Zardana were found medium tolerant, SD1200/51, Khirman, V-7012 medium sensitive and RWM-9313, SH-43 sensitive. Tolerant wheat genotypes were successful in maintaining low Na and high K uptake and high K/Na ratio.
