Twelve clones selected for high yield of capsules and a local standard were sown in the field at Appangala in July 1990 and evaluated in 1992-93 for boldness (100-capsule weight), chlorophyll content of capsule husk and content of essential oil and its components, 1,8-cineole and alpha -terpinyl acetate. Clones were not significantly superior to the local standard for boldness, but 5 clones had significantly higher husk chlorophyll content, indicating their superiority with respect to green capsule colour. All the clones yielded significantly more essential oil per hectare than the local standard, and 9 clones were superior for essential oil content of the capsule, 3 of them significantly so. Essential oil yield was highest in Selection 7 (190 kg/ha) and lowest in the local standard (54 kg/ha). Seven clones, including Selection 12, had a higher ratio of alpha -terpinyl acetate to 1,8-cineole compared to the local standard, which is a desirable quality attribute. Selections 2, 11 and 12 yielded bold, green capsules superior to those of the other entries.
