ABSTRACT:
A new and distinct variety of peach rootstock denominated ‘HBOK 50’ is described. The ‘HBOK 50’ peach rootstock offers size control ability, root knot nematode resistance, less wood from dormant and summer pruning, and production of fewer root suckers. ‘HBOK 50’ has contributed to size reduction of compound trees when it is used as a clonally-produced rootstock with the fresh market peach “O'Henry”. No evidence of graft incompatibility or other abnormalities have been noted in such circumstances. Fruit on compound trees with ‘HBOK 50’ rootstocks is either similar in size or smaller than ‘Nemaguard’. The ‘HBOK 50’ rootstock displays root knot nematode resistance levels similar to ‘Nemaguard’ and more resistant than ‘Lovell’.
