Abstract

To evaluate the adaptability and performance of new and promising apple rootstocks in the dwarfing size-control category, a NC-140 regional rootstock trial was established in 2003 at 14 sites in the United States (AR, CA, IA, GA, KY, ME, MI, NY, OH, PA, UT, WI), Canada (BC), and Mexico. The Iowa planting, located at the ISU Horticulture Research Station, includes 23 rootstocks with new selections from the Cornell-Geneva breeding program (G, CG.), Russia (B.), Czech Republic (J-TE), Japan (JM.), and Germany (PiAu). These rootstocks are being evaluated with Gibson Golden Delicious serving as the test cultivar. This report summarizes the treegrowth and production characteristics through the 2008 growing season.
