Abstract:: To determine the α,β-amylase activity and total amylase activity in 25 radish varieties，field experiments used randomized block design and repeated 3 times，α-amylase，β-amylase and total amylase activity were estimated by the 3，5-dinitrosalicylic acid method after fleshy root harvest，for providing a reference and establishment relationship of α-amylase，β-amylase and total amylase activity.The results showed that there were significance differences of α-amylase，β-amylase and total amylase activity in different radish varieties；the A04，S01，A17，A20，S05 and A07 were the higher α-amylase activity and the A19，A06，A17，A12 and S03 were the the higher β-amylase and total amylase activity.The ratio of α，β-amylase activity in total amylase activity was 8.11% to 25.57% and 75.26%~91.89%，respectively and the relationship of them was Y_{Total amylase activity}=-0.029+1.039X_α-amylase activity+0.998X_β-amylase activity.
