Correlation and path analysis were performed for fifteen morphological and chemical (monoterpenes and sequeterpenes) traits in Artemisia annua. Significant positive relationship and direct effect was observed of artemisinin yield with plant height, branching pattern (number of primary, secondary and tertiary branches), petiole length, ketone and 1, 8 cineol while negative association was observed with artemisinic acid, α-pinene and camphor. Oil content was negatively associated with leaf characters namely lamina length, lamina width and petiole length. Oil has negative effect on artemisinin content. The information can be used as a useful reference for elucidating relationship of Artemisinin (sesquiterpene), essential oil (monoterpene) with m
