Abstract：Sepal shape of 85 materials，including inbred lines of tomato（Lycopersicon esculentum Mill.）and cherry tomato，were observed．The results show that there is a gradual change of sepal shape from less than 90 degrees to over 180 degrees from flowering to fruit maturity．The sepal shape can be classified into spread，up-spread，upright and scroll 4 types at red ripe stage．The following is the angle between stretching direction of sepal and the fruit vertical axis．Spread is in the range of 90-100 degrees，up-spread is 101-170 degrees，upright is 171-180 degrees，scroll means the angle is more than 180 degrees，and it is entad curling．The ratios are 4.71 %，1.18 %，17.65 % and 76.47 %，respectively.
