Interspecific Hybridization in the Genus Abies. Klaehn, F. U. and Winieski, J. A. 11(5/6):130–142.
abstract   bibtex   
A pattern of crossability in Abies is presented, based on a compilation of existing data on natural and artificial hybrids, and further controlled pollinations (in all, 137 attempted interspecific crosses) made in spring 1960 are reported. Twelve of these crosses produced seedlings that are under consideration for putative hybridity. In inbreeding trials, seedlings of inbred A. concolor and A. (nordmanniana x cephalonica) survived 2 growing seasons in the nursery. With the results of these experiments, an expanded and modified crossability pattern is drawn up in which crossability is shown within and between species of different regions, though the degree of crossability is not shown. Inferences drawn from this table are discussed. it is suggested that a geographic, rather than a genetic or physiological separation of species has occurred as the genus evolved
