One C!f The Asian Vegetable Reasearch and Development Center programes is to get superior varieties potato. The experiment was objected to study somaclonal veriety of several introduced potato varieties in order to select superior varieties from them. The plant height, the number of node, and petiole length of Atlantic cultivar were significant different from somaclonal cultivars, even though the number of stem and intrnode length were not defferent. However the number and weight of tuber Red Pontiac, Desiree, Russet Burbank, and Eba significant defferent from those somaclonal cultivars, but not the Atlantic cultivar. According to the principal component analysis for seven quantitative variables of the 34 plants numbers, there were two principal variables. The both variables Ig. variable J and 2, were able to explain about 79.3 % of the total variation. Therefore using the first and second variables may be explained the most of data variation. Somaclonal variation induced by irradiation were able to improve morfologis characters and yield, especially for Atlantic cultivar. Each of Atlantic and Red Pontiac somaclonal cultivar number hadfar relationship with their mother plants.
