During 2011, the length of primary branches was measured in individual seedlings of firs representing 15 crossing variants. Measured branches were divided into separate groups according to the number of secondary twigs. Our data indicate the possibility for differentiation between the hybrid combinations based on length of their primary branches. The interspecific combinations A. pinsapo × A. alba and A. alba × A. pinsapo were more similar to mother species in this trait rather than to paternal parent. A given combination of different age differed primarily by the number of primary branches with a higher number of secondary branches in older seedlings. Comparison involving both primary and secondary branches appears to be more efficient in discriminating between hybrid combinations than comparison primary based on secondary branches alone.
