Christophs Apfel. My small tree is starting to make tiny fruit. Luckily sorbus domestica is self-fertile and when it pollinates itself there usually is only one seed in each fruit. Seen as this variety fruits at a really young age i want to sow the seeds and see if the offspring will inherite this trait. It will be interesting to see the size and appearance of the fruit. Hopefully the tree won't get sick and will manage to make some fruit and therefore seed. If the early flowering trait is passed on to the next generation these seedlings will make excellent sorbus domestica dwarf rootsock.
