Abstract

Crop characteristics involving cone size average number of seeds per cone and seed germinability have been studied for three hybrid swarm populations of Pinus mugo and P sylvestris two pure P mugo populations and one pure P sylvestris population in northern Slovakia Generally reproduction capability characteristics were significantly reduced in hybrid swarms in relation to the control populations Although there were no consistent differences between hybrid swarms and control populations in the average number of seeds per cone or cone size seed germination rates and full seed production in hybrid swarms were lower than for the control population of P sylvestris and one of the pure populations of P mugo Based on these data a conclusion has been drawn postulating partial rather than full fertility of the hybrid swarm populations of P mugo and P sylvestris
