The grafting clone 1339 grew in the seventh plot of biclonal seed orchard in Suichang County of the Zhejiang province, their cuttings were taken from the Changle Chinese fir seed orchard in Yuhang.and there were distinct variables among the individuals. Compared the grafted clone 1339 in Suichang orchard with the clone 1339 in the Changle orchard, it was found that there were obvious diversity and similarity in aspects of morphology ,flowering period,flower amount and allozyme between the two clones. The results confirm that the grafted clone 1339 having exceptionally characteristics should be a kind of asexual hybrid. Furthermore, we can get some implications: (1) when using the molecular marker technique, constructiog clone fingerprint, and dividing materials with the difference of 1-2 bands into two clones, we must be specially careful, because this result possibly a wrong outcome. (2) when establishing, tree graft seed orchard, cutting orchard or gene bank, we should better use the identical clone material to make the stock; under the difficult condition, maybe makes same family seedling use stocks .This may maintain cutting-strips to accept the same genetic influence. (3) when evaluating the growth quantity, flowering and seed-bearing yield of different grafting clones, the influence of asexual hybridization on cutting-strips should be considered because the stocks are different sources, the different stock's genetic background will produce different genetic effects.
