Abstract: AFLP was applied in this experiment to detect the genetic ident ity of Malus xiaojinensis from natural population. The fingerprint ing of 20 seedlings of M. xiaojinensis with 8 pairs of primers showed that M. xiaojinensis in natural population had a high degree of genetic ident ity, its genetic similar coefficient being 98. 92 %. Genetic difference also existed in this population, 1. 08 %fragments were different fragments. The patterns analysis
indicated that these different fragments were resulted from gene recombination of sexual hybridizat ion.

Key words: Malus, Malus xiaojinensis, AFLP, Genetic identity
