Pollination dynamics variation in a Douglas-fir seed orchard as revealed by microsatellite analysis

Popis výsledku v původním jazyce

As part of a multi-year monitoring study of pollination dynamics in a second generation Douglasfir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard, we estimated with the aid of eight microsatellite markers three important reproductive biology characteristics affecting the genetic worth and diversity of seed crops. Namely parental reproductive success, pollen contamination, and selfing rate. The obtained results were compared to those from two previous years to gauge appropriate seed crop management practices and ultimately allow approximate generalization of seed crop genetic quality. We determined that 80% of parental gametes were produced by 52% of the parents, 13% of paternal gametes resulted from pollen contamination (i.e., gene flow), and 12% of the seed were the product of selfing. The obtained results were in line with those observed for 2005 and 2009 where 80% of gametes being produced by 37-48% of the parents, 10-18% pollen contamination, and 15-17% selfing rate. The observed reproducti
