Abstract

The new ‘HBOK 27’ rootstock is an ‘OP-F2’ plant from an F1 plant of an intraspecific hybrid between two peach parents that is useful as a commercial under-stock for peach and nectarine cultivars. The ‘HBOK 27’ rootstock has been successfully propagated clonally by leafy cuttings and tissue culture. The ‘HBOK 27’ rootstock is graft compatible with peach scion cultivars, and confers moderate vigor control to the compound trees. Peach trees grown on the ‘HBOK 27’ rootstock are productive, require less pruning than trees on grown on the standard rootstock ‘Nemaguard’, and produce fewer root suckers than ‘Nemaguard’. The ‘HBOK 27’ rootstock shows moderate resistance to root knot nematode [ Meloidogyne incognita (race 1) isolate ‘Beltran’] that is slightly less than that of the standard rootstock ‘Nemaguard’.
