The choiceness varieties of Canarium album were tested in three different places of Guangdong. The study researched the 3-4a trials after engrafting, the results were as follows:(1) The results of variance anaylsis indicated that there were highly significant differences in yield per plant and yield per crown projection area among clones, and the height, stem diameter and crown side were highly significant in some test sites. It showed that genetic diversity existed in yield per plant among clones, and selecting high yield clones were effective.
