Cytogenetics of Lavandula gibsonii, an endemic lavender from the Western Ghats, India

Year: 2023

Type: article

Abstract: Lavandula gibsonii is an endemic lavender that occurs in the Western Ghats of Maharashtra and Tamil Nadu states of India. It is aromatic and has insecticidal properties. We studied the cytogenetics of the species for the first time. The chromosome number was observed to be 2n=40 and the small chromosomes ranged from 0.95 to 2.05 µm. Meiosis was normal with n=20 bivalents at diakinesis. Somatic metaphase chromosomes with submedian region centromeres dominated the karyotype. The karyotype formula was 2m + 18sm. The karyotype was found to be asymmetrical and fell into Stebbins’ 4B category. The base number (x) of section Chaetostachys in which Indian species are placed needs to be reassessed.
