Comparative study of needle length in progenies of three species and nine interspecific hybrids of firs (Abies sp.) revealed the preponderance of A. nordmanniana x A. alba and A. concolor x A. grandis hybrids over the controls from open and self-pollination of the maternal species. The same type of differences has also been observed between the two hybrids of A. pinsapo as well as between the five additional hybrids with four Abies species involved. The number of stomata per unit of needle length was variable and only partially correlated with the length of needles.
