Abstract: In order to evaluate the pulp color and browning degrees about apple cultivars after the fresh-cut fruit treatment and look for the anti-browning resources，40 apple cultivars were employed to carry out the research in the pulp color and browning diversity and then the significant and cluster analyses were carried out. The results showed that the main types of apple pulp color are yellow，white and green. One hour later after the fresh-cut fruit treatment，the yellow pulp turned into yellow-brown，the green and white pulp became grey-brown mostly or turned into yellow-brown. The pulp browning phenomenon in apple cultivars occurred widely with the phenotypic diversity. Among the cultivars there were obviously differences in the pulp browning degree，especially for the cultivars with different ripened stage，in which the later the mature stage was，the less the browning was.‘Huahong’and‘Huaguan’were the much better anti-browning cultivars.
