Greenhouse screening of 49 dwarf rootstock candidates

Author: Amit Dhingra, Kate Evans

Published: 2020

Summary: All the seedlings representing 49 dwarfing rootsock candidate were successfully introduced and established into the micropropagation process as a means to preserve the precious genetic material. In addition, a minimum of 20 clones each were established and rooted in the greenhouse. The clones achieved the necessary height, however, the caliper has remained inadequate for budding. The clones will be grown for another season in the greenhouse prior to being budded.
