Abstract: Identification and classificati0n of 39 litchi varieties were studied based on A兀P analysis．Threepair of primers(EcoRI AAC+MseI CTG，EcoRI AGC+MseI CAT，EcoRI ACC+MseI CAT)were screenedfrom 64 pare ofprimers．rI1le an alysis ofgenetic diversity among litchi varieties indicated on morphological level lessabundant than molec~ar leve1．The cluster analysis results showed that the 39 cuhivars could be divided into 6groups．It is diferent from the traditional classification system based on peel morphology including peel smoothness，scale size．scale arrangement．rI1le results showed peel morphology Call not be used for litchi varieties classificationas the only criterion．The molecular marker standard map of the main litchi varieties Was established ．Two varieties(Litchi chinensis ‘Guiwei’and Litchi chinensis ‘FeizSxJao’) come from diferent arIea were identified．
