Abstract
Eighteen Prunus rootstock cultivars and selections budded with either Redtop or Redhaven peach and another 11 budded with Redhaven were planted at 2 locations in South Carolina in 2001, 2002, and 2003. In 2001, Redtop trees were planted near Clemson, South Carolina as part of a NC-140 Cooperative Regional Rootstock Project.
A Redhaven NC-140 planting was added in 2002 adjacent to the Redtop. A 2003 Redhaven test was planted on a severe bacterial canker site near Columbia, South Carolina.
There were 20 different rootstocks tested, which included three peach seedling rootstocks, Lovell, Bailey, and Guardian™ BY520-9 [selection SC-17]. Clonal rootstocks included peach x almond hybrids BH-4, SLAP, and Monegro; peach x plum hybrids K146-43 [=Controller 5], K146-44, and P30-135 [=Controller 9]; interspecific plum hybrids Citation, Hiawatha, Jaspi and Julior; interspecific Prunus hybrids Cadaman, VVA-1 [=Krymsk 1], VSV-1 [=Krymsk 2]; and Prunus L. species selections Adesoto 101 [=Empyrean 101], PumiSelect, Mr.S 2/5, and Penta [=Empyrean 2]. At the Clemson location, PumiSelect and SC-17 were the most vigorous rootstocks, while Jaspi, VVA-1, Julior, and K146-43 produced the smallest trees.
Cumulative fruit yields were highest on the peach seedling, peach x almond, Cadaman, and PumiSelect rootstocks.
Lowest yields were from trees on the Jaspi, VVA-1, and Julior rootstocks.
Fruit weight was significantly larger on the peach seedling, peach x almond, Cadaman, and Hiawatha rootstocks.
Tree survival was low on Jaspi (i.e., bacterial canker), VVA-1, and PumiSelect (i.e., wind breakage) rootstocks.
At the Columbia site, every tree on Adesoto 101, Monegro and VVA-1 died from bacterial canker in the 2nd leaf.
Many trees on K146-43 also died, whereas all trees on SC-17, Lovell, Mr.S. 2/5, PumiSelect, and VSV-1 rootstocks were alive.
