Pedigree and mating system analyses in a western larch (Larix occidentalis Nutt.) experimental population

Original language description

The mating pattern and gene flow in a western larch (Larix occidentalis Nutt.) experimental population was studied with the aid of microsatellite markers and a combination of paternity-mating system analysis. The commonly difficult to assess, male gametic contribution was determined with 95% confidence and its impact on genetic gain and diversity was determined. Male fertility success rate ranged between 0 and 11%.Male reproductive output parental imbalance was observed with 50% of the pollen being produced by the top 5% of males while the lower 39% males only produced 10% of the pollen. A significant difference was observed between male effective population size (genetic diversity) estimates from paternity assignment compared to those based on population?s census number (21 vs. 41); however, this difference did not affect estimates of genetic gain. A total of 221 full-fib families were identified (sample size range: 1?8) and were nested among the studied 14 seed-donors.
