Thirty quantitative and qualitative characters related to the vegetative and reproductive growth were recorded on 257 plum seedlings in Karaj during 2006 to 2009. Results showed high variability in studied characters among seedlings. Height of seedlings were 60-231, 100-317 and 430-125 cm in the second, third and fourth years of growth respectively. Increase in height was 4-197 cm between the second and third, and 9-141 cm between the third and fourth years of growth. Simple correlation coefficients were significant among some important characters such as height and trunk diameter, growth habit, vigor and yield. In cluster analysis seedlings were divided into five groups, including very strong, strong, intermediate, weak and extremely weak groups. Based on the results, slow-growth seedlings, suitable for rootstock, were S11-23, S11-25, S11-26 and S7-37 and high-growth genotypes were S1-1, S1-20, S1-22, S3-1, S9-3 and S4-30.
