Abstract: 
Current study was conducted to compare seed germination characteristics of 12 spring rapeseed cultivars with different 1000-seed weight, in laboratory and field steps on the base of randomized complete block design with four replications; The rapeseed seeds were compared in four tests including standard germination test, accelerated aging test, cold test and electrical conductivity test, in the laboratory.Moreover, the seeds were sowed in the research field of University of Tehran (Abooreihan campus) to compare their emergence ability. The result showed that the effect of cultivars were significant on all tested traits, with the exception of the. length of plumle in standard tests.According to the tables of mean comparison and correlation, cultivars with higher seed weight were better in most characteristics related to germination and emergence ability such as the percentage of germination and emergence and their rate, seedling dry weight and the length of radicle, while IOOO-seed weight effect was not significant on the length of plumle. On the base of these results, the increase of seed germination and emergence ability of different rapeseed cultivars due to increase of 1000-seed weight strongly shows the relationship between the increase of reserved substances quantity in seed, and the increase of germination ability and seed growth.Furthermore, cold and accelerated aging tests are the best experimental test to predict the percentage of emergence ability of the rapeseed in the field.
