Prunus Rootstock Affect Long-term Orchard Performance of `Redhaven' Peach on Brookston Clay Loam

Abstract

<jats:p>Performance of `Redhaven' peach <jats:italic>[Prunus persica</jats:italic> (L.) Batsch.] propagated on nine experimental <jats:italic>Prunus</jats:italic> rootstock was evaluated over 8 years beginning in 1984, in a randomized complete-block experiment with 10 replications on a Brookston clay loam soil type near Harrow, Ont. This experiment was part of an interregional NC-140 peach rootstock experiment. Significant rootstock-induced effects were noted for increase in trunk cross-sectional area, cumulative tree height and spread, cumulative number of root suckers, yield, average fruit weight, yield efficiency, winter injury, cold hardiness, and tree survival. None of the clonally propagated rootstock gave satisfactory overall performance. All trees on GF655-2, 80% on GF677, 60% Self-rooted, and 50% on GF1869 were dead by the eighth year. In addition, suckering was a major problem on GF1869 and a moderate problem on GF655-2. `Citation' induced the most scion dwarfing but had the lowest yields and low yield efficiency. When yield, yield efficiency, fruit size, and tree mortality were considered together, the four peach seedling rootstock performed better than the other <jats:italic>Prunus</jats:italic> rootstocks and were ranked as follows: Siberian C, Halford, Bailey, and Lovell. Of these, the first three could be recommended with the most confidence to commercial growers who grow peaches on fine-textured soils in northern regions.</jats:p>

Influence of rootstock on orchard productivity and fruit quality in peach cv. ‘Redhaven’

“…The presence of root suckers was observed only on 'GF 655/2', which agrees with reports by Iglesias et al (2004) and Layne (1994). Some trees died in our experiments.…”

“…Some trees died in our experiments. Mortality on the rootstock P. pumila was 50%, while on 'GF 655/2' it was 8%, which was less than stated by Layne (1994), where all trees died by year-8. On 'GF 677', the mortality was 17%, and on 'Missour' it was 25%.…”

Genetically Diverse Peach Seedling Rootstocks Affect Long-term Performance of `Redhaven' Peach on Fox Sand

“…Cumulative tree survival to the tenth year is an important factor to assess rootstock adaptation to a given soil type and climatic zone. Low survival (17%) associated with 'Halford' and 'Lovell' ( Table 8) was indicative of inadequate adaptation for very light, sandy soils in southern Ontario, despite satisfactory survival on heavier soils in Ontario (Layne, 1994) and in regions farther south (Dozier et al, 1984;Yadava and Doud, 1980). These rootstock seed sources originated in California and were not selected for cold hardiness or canker tolerance, the major causes of tree death in Ontario (Layne, 1984).…”

Rootstock and Training System Affect Sweet Cherry Growth, Yield, and Fruit Quality

“…The effects of rootstock genotype on fruit yield and quality and tree vigor have been well documented in many tree species, especially apple (Malus ×domestica Borkh.) (Autio and Southwick, 1986;Fallahi et al, 2002;Marini et al, 2002;Schecter et al, 1991;), but also for peach (P. persica L.) (Kappel and Bouthillier, 1995;Layne, 1994) and citrus (Roose et al, 1989;Wheaton et al, 1991). New rootstocks for sweet cherry have recently been developed and adopted commercially (Lang, 2000;Perry et al, 1997), albeit on a limited basis in North America.…”
