With attention to need our country to nutriant oil and protein, introduction of new and high yield cultivars of soybean can play and important role in increasing of oil seed production. in order to evaluation of new soybean lines and introduction of highyield and adaptable cultivars, four pure line of soybean with cv. williams and cv. century were compared in experiments based on CRB design for two years (1999-2000) in Khoy and Miandoab stations. During the growth period, Usual agronomic treatment was done and some agronomic and morphological caracteristics of these lines was recorded. After harvesting, grain yield, 1000 Kernel weight, oil and protein content measured. For date of each year simple variance analysis, and in the end of second year combine analysis were done for each location and for all data. Data means were compared with each other using Duncan mathod and correlation between traits was determind. Stability analysis were done using: environmental variance and coefficient of variability, Wricks ecovalance, regession coefficient, regression deviation, coefficient of determination and Rank method. Based on abtained results line Williamsأ—Chpippwa 1 with 2893 Kg/ha grain yield is suitable for North of W. Azarbayjan, and line Blackhawkأ—Granglbe 2 with 2868 Kg/ha grain yield is suitable for south of W.Azarbayjan. Based on stability analysis of grain yield line blakhawkأ—Granglbe 2 is selected as a stable line.
