Abstract
Badri tulsi (Origanum vulgare L.) is a spice, medicinal and aromatic perennial herb belongs to Lamiaceae family. This plant possesses diverse biological
potential due to variability in oil yield related traits.The present study has been conducted on morphological and anatomical characterisation of Origanum vulgare L. germplasm collected from Uttarakhand region.The present studies revealed that plants were generally perennial with erect type of habit in most
cases whereas semi erect habit were reported in 4 germplasm (Ov-4, Ov-6, Ov-11, Ov-12) collected from Champawat, Chamoli, Dehradun, Joshimath
districts respectively. Minimum plant height was reported in Ov-14 germplasm (24.8±1.42cm) collected from Badrinath whereas maximum plant height was
observed in Ov-12 (86±1.69cm) germplasm collected from Joshimath district. On leaf length characterization, the minimum leaf length was found in Ov-9
(0.65±0.03cm) while maximum leaf length was reported in germplasm Ov-13 (2.3±0.14cm).In anatomical investigation, transverse section of stem was
quadrangular and outer layer was covered with cuticle followed by epidermis with two types of trichome - simple and glandular. Maximum number of trichome
on the stem was observed in Ov-11 germplasm and minimum were in Ov-7 germplasm. In transverse section, leaves were covered with cuticle followed by
single layer of upper and lower epidermis. Thick cuticle was present in Ov-1, Ov-2 and Ov-12 accessions. Epidermis consists of uniseriate, multicellular long
simple and glandular trichome. Diacytic type of stomata was reported in both the surfaces of leaves in all studied germplasm. The findings of the present
studies revealed that morphological and anatomical characterization could be used as tools to distinguish the variability among the germplasm of Origanum vulgare L. collected from different regions of Uttarakhand, India. Thus, these studies will be useful in future for genetic enhancement and development of
varieties with high biomass yield, and desirable agronomic characters with high essential oil content in respect of the conservation of bio resources.
