Source population characteristics affect heterosis following genetic rescue of fragmented plant populations

Pickup, Melinda; Field, David L.; Rowell, David M; Young, Andrew

Description

Understanding the relative importance of heterosis and outbreeding depression over multiple generations is a key question in evolutionary biology and is essential for identifying appropriate genetic sources for population and ecosystem restoration. Here we use 2455 experimental crosses between 12 population pairs of the rare perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational (F1, F2, F3) fitness outcomes of inter-population hybridization. We detected...[Show more]
