No. Pandas only have 42 chromosomes, while all other bears have 72, except for the spectacled bear which has 53. Due to the difference in the number of chromosomes, neither the panda nor the spectacled bear interbreed with other varieties. Source: http://www.cryptozoology.com/articles/mysterybears.php Shultz: Perhaps you can force them to copulate. You can't force them to breed, because they simply can't. In virtually every case where cross-species hybrids occur, the parents have either the same number of chromosomes or only one more/less. As indicated in my original answer, the difference in the number of chromosomes between pandas and all other bears is simply too great to allow cross-breeding. Even if you were to attempt in vitro fertilization, no viable embryo would result. Please make sure you read and understand the answer before you post your rating. Also, please remember to rate answers based on whether they answer the question that was asked. Since I correctly answered the question that was asked, I don't understand why you rated the answer poorly.

Each of the four members of the genus Ursus has interbred with at least one other member, and there is evidence that the Sloth Bear and the Sun Bear interbreed. There are no reported hybrids involving either the Spectacled Bear or the Giant Panda Bear. It should be noted at the outset that lack of hybridisation data does not mean that hybrids cannot occur. By far the majority of hybrids have occurred in zoos where animals have been kept together rather than in isolation. As a general policy, zoos do not set out to research hybridisation potential, and the contemporary trend is to avoid the incidence of hybrids, in order to preserve the identity of species. so yes they can breed it just hasnt been documented yet.
