In order to evaluation and yield comparison of soybean purelines of as many as 29 soybean lines with Williams cultivar as check were conducted.. at agricultural and natural resonrces reseach center of lorestan du~ign two years (2005-2006). The statistic desirig in this study was Random completely blocks with 4 ' replications. During growth Season some characters such as days to in initial flowering ,date of maturity, d~y to maturity, plant height and pod per plant were measured. ,on five random plants. ' . After harvesting seed yield and lOOO-seed weight weighted and oil percent and protein percent' determinated . The results indicated, that years were not significant difference but plant height, number.noqe per stem, lOOO-seed weight, oil percent, protein. percent ad had significant difference at 1% level a.nd pod per; plant had significant differences at 5% level. Line 4(SRS4S0x,Krasnodar778) showed the highest yield (4647.6kglha) '. ..' and check cultivar,wtth 3246.6 kg/ha was 2 rank. Line 28 with yield 2937.61. kg/ha was 3 rank Key word: soybean, yield comparison, pureline
