Bark oil in various lines ranged from 1.2% to 4.9%, leaf oil 0.4% to 1.6% and bark oleoresin 6.0% to 10.5%. The cinnamaldehyde content of leaf oil ranged from 40% to 86%, and that of bark oil 61% to 91%. The coefficient of variation was high for bark and leaf oil (26.76% and 26.74% respectively). (In this trial cassia plants were maintained and harvested similarly to Sri Lankan cinnamon and hence may not be comparable with the practices prevalent in the producing countries).

Based on quality and other characteristics four promising lines were identified. Two lines (A1 and C1) have high bark oleoresin (10.2% and 10.5%, respectively) and two others (D2 and D3) have high bark oil (4.7% and 4.9%, respectively) and high cinnamaldehyde in bark oil (91.0% and 90.5%, respectively). Taking the overall yield, chemical and flavour profiles, C1, D 1, and D3 were selected and are in pre-release yield evaluation trials (Krishnamoorthy et al, 1999, 2001).

Little crop improvement work has gone into the Chinese cassia in China or Vietnam, where the production is located. This is true of the Indonesian cassia as well. In all these countries cassia cinnamon is treated, and is managed and exploited as a forest tree crop.
