Congruence between theory and practice: reduced contamination rate following phenotypic pre-selection within the Breeding without Breeding framework

Popis výsledku v původním jazyce

Wind-pollinated seed orchards are often subjected to pollen intrusion from outside pollen sources. When wind-pollinated seed orchards seed are used to establish progeny trials, the offspring is expected to harbour varying proportion sired by outside sources. Theoretically the magnitude of selection differential between the orchard's population and the contaminant pollen sources will affect the proportion of offspring resulting from outside pollen sources matings. If phenotypic pre-selection is implemented through selecting the top phenotypically ranked individuals from these progeny trials, then it is expected that the proportion of individuals sired by outside pollen sources will be lower within the pre-selected vs. unselected individuals. Here, we present empirical data from two Scots pine progeny trials supporting these theoretical expectations. The observed reduced contamination rate among fingerprinted elite offspring was 3.9 and 4.2%, suggesting a significant reduction in compari
