Salix alba x babylonica hybrids

Hybridization is in flowering plants an important evolutionary force that might change sex distributions and sex determination systems (SDS). However, little is known about processes in the first hybrid generations. Here we study a cultivated putative hybrid cross of weeping willows, Salix alba x babylonica, to get insights into effects of hybridization into SDS. We analyzed genetic structure of pure Salix alba, pure Salix babylonica, and the putative hybrid crosses in Central Europe using RADSeq data.
