NC-140 REGIONAL CHERRY ROOTSTOCK TRIAL (1998) - RESULTS FROM WESTERN NORTH AMERICA
This regional rootstock research trial was planted in spring 1998 in British Columbia, California, Colorado, Oregon (2 sites), Utah, and Washington. Bing was the scion variety and the rootstocks tested were: mazzard seedling (Prunus avium); P. mahaleb seedling; Gisela® 3, 4, 5, 6, and 7 interspecific hybrids; Giessen (Gi) 195/20 and 318/17 hybrids; Tabel® Edabriz (P. cerasus); and Weiroot (W) 10, 13, 53, 72, 154, and 158 (P. cerasus). The only rootstock that has not lost any trees to date is Gi 195/20 and the rootstock with the greatest loss was mazzard, followed by Gisela® 4. Utah was the location with highest mortality. The most vigorous trees at the end of the 1999 growing season were in Washington, followed by Corvallis/Oregon. The smallest trees were in Colorado. Rootstocks that promoted the greatest vigor thus far were Gisela® 6 and Gi 318/17. The most dwarfing rootstocks thus far were W53, followed by W72 and Edabriz.
