The effect of rootstock in long-term performance of the peach cultivar ‘Redhaven’

Peach is the third most important deciduous tree fruit in the world and have a long history.
Peach trees are formed from a combination of scion and rootstock, so a good union between them is required.
Rootstocks of different genetic origin have an influence on the growth, yield, phenology and fruit quality of peach trees.
The influence of different rootstocks for peach (Prunus persica L.) on vigour, productivity and fruit quality was studied at the Fruit Growing Centre Bilje near Nova Gorica for 7 consecutive years. ‘Redhaven’ was grafted on 11 different rootstocks: ‘GF 677’, a peach seedling, ‘Monegro’, ‘Barrier’, ‘Cadaman’, ‘Adesoto’, ‘Mrs 2/5’, ‘Julior’, ‘Isthara’, ‘Penta’ and ‘Tetra’. The rootstock had a significant effect on individual tree circumferences, canopy volume, number of fruits per tree, yield per tree and per hectare, yield efficiency, and also on fruit quality (fruit size, soluble solids content and firmness). There were vigorous trees on virgin and replant soils on rootstocks ‘Monegro’ and ‘GF 677’. Under replanting conditions, the rootstocks ‘Isthara’ and ‘Tetra’ and, for virgin soil, the peach seedling, ‘GF 677’, ‘Isthara’ and ‘Mrs 2/5’ showed the greatest potential.
