Interpretive Summary: Regional rootstock tests provide critically important performance data for growers and extension personnel in planning a commercial orchard. The NC-140 peach rootstock trials have been providing this type of information since 1984. In the most recent installment ‘Redhaven’ peach on 8 different rootstocks were planted at 17 sites in North America in 2002. Rootstocks included plum and plum hybrids, i.e.,ee ‘Adesoto 101’, ‘Mr.S.2/5’, ‘Penta’, ‘VSV-1’ (‘Krymsk 2’), ‘VVA-1’, (‘Krymsk 1’), ‘Pumiselect’, a peach-davidiana hybrid, ‘Cadaman’, and a peach seedling, ‘Lovell’, as a standard. After 5 years ‘Pumiselect’ and ‘VSV-1’ appeared to be suffering from poor survival and productivity that would severely limit their commercial utility. Other plum and plum hybrid rootstocks generally were less seriously handicapped. ‘Cadaman’ appeared comparable to ‘Lovell’ in both vigor and productivity but it offered no clear advantages that would justify recommending it over ‘Lovell’ at that time. However, ‘VVA-1’ showed promise as a dwarfing rootstock with good fruit size and productivity superior to ‘Lovell’.

Technical Abstract: In 2002, a trial consisting of 8 rootstocks was planted at 17 sites in the United States, Canada and Mexico. ‘Redhaven’ was the scion at 10 sites and ‘Cresthaven’ at the other 7 sites. The rootstocks tested were ‘Adesoto 101’ , ‘Mr.S.2/5’ , ‘Penta’ , ‘VSV-1’ (‘Krymsk 2’), ‘VVA-1’ (‘Krymsk 1’), ‘Pumiselect’, ‘Cadaman’ and ‘Lovell’. After five years, trees on ‘Cadaman’ were similar in size and productivity to ‘Lovell’. ‘Pumiselect’ and ‘VSV-1’ exhibited many problems with survival, suckering and fruit weight. ‘Adesoto 101’, ‘Mr.S.2/5’ and ‘Penta’ all showed potential as semi-dwarfing rootstocks although mortality and suckering were excessive at some sites. ‘VVA-1’ showed potential as a dwarfing rootstock with a trunk cross sectional area 35% of ‘Lovell’. It also had fruit weight equal to the more vigorous rootstocks and the highest yield efficiency of the trial.
