The rootstock’s role in modernizing plum culture

Rootstocks have an important role in modernizing plum culture.
During the 1970-2014 period a rootstock breeding program for plum was launched in Romania in two locations: SCDP Valcea and R.I.F.G. Pitesti.
Seven rootstocks have been named at SCDP Valcea and two at R.I.F.G. Pitesti.
The plum rootstocks obtained have specific agro-biological characteristics: low vigor (‘Oteşani 8’ and ‘Mirobolan dwarf’); medium vigor (‘Rival’, ‘Pinval’ and ‘Oteşani 11’); high vigor (‘Miroval’, ‘Mirobolan C₅‘, ‘Oltval’ and ‘Corval’); propagation through seeds and also clonal (‘Oteşani’, ‘Miroval’, ‘Mirobolan C₅‘ and ‘Mirobolan dwarf’); clonal propagation (‘Rival’, ‘Oteşani 11’, ‘Oltval’, ‘Corval’ and ‘Primval’); good compatibility with European plum cultivars (‘Oteşani 8’, ‘Oteşani 11’, ‘Rival’, ‘Pinval’ and ‘Corval’); weak compatibility with ‘Tuleu gras’ and ‘Reine Claude D’Althan’ plum cultivars (‘Mirobolan’, ‘Mirobolan dwarf’, ‘Mirobolan C₅‘ and ‘Oltval’); resistance to main pests and diseases with exception of Sharka (all nine plum rootstocks); good productivity induced to the cultivars (all nine plum rootstocks). ‘Oteşani 8’ and ‘Mirobolan dwarf’ rootstocks can be used for high density plum orchards (with densities of 1000-1200 trees ha^-1).
