title: Genetic variation of F1 hybrids from controlled crosses between Pinus montana var. rostrata and Pinus sylvestris in morphological needle traits.
abstract: One hundred and seventeen hybrids, representing ten families from controlled crosses between Pinus montana var. rostrata and Pinus sylvestris, were examined in respect to six morphological traits of two-year-old needles. The biometric data obtained from the measurements provided a basis for multivariate statistical analyses, including discriminant analysis and Mahalanobis distances as principal methods. The analysed families formed two complexes, which were significantly different. The main traits responsible for the distinction were numbers of stomatal rows on both sides of the needles.
