Abstract：Upland rice has many advantages such as drought resistance,barren tolerance and wide adaptability.The upland rice germplasm resources were widely collected.Then 2 lines,named as Nonghan 1 and Nonghan 2,were obtained after purified and rejuvenated.The salinity tolerances of Jiaohan 1 and Kunhan 1,which were suitable to be planted in Shandong,and Nonghan 1 and Nonghan 2 were identified at germination and seedling stages.The results were as followed.When treated with 2％ NaCl solution or different salinity concentrations of sea water,the seed germination rate of Kunhan 1 was the highest.Second was Jiaohan 1.When grown in 7‰‰ sea water for 15 days,the leaf dead rate of Kunhan 1 was the lowest.Second was Jiaohan 1,too.In a word,Kunhan 1 had stronger salinity tolerance at germination and seedling stages,belonged to relatively strong salinity-tolerance upland rice,and had the potential to plant and popularize in the saline-alkali land in the Yellow River Delta.
