Genetic diversity in bamboo germplasm in TBGRI using ISSR markers


Bambusetum in Tropical Botanic Garden & Research Institute (TBGRI) has 660 accessions of Bamboos belonging to 60 species spread across 12 hectares of land area. The collection includes species mainly from the Western Ghats, north-eastern region of India, South East Asia and a few cultivated ones. 

Inter-single sequence repeat (ISSR) markers were used as a tool to analyze natural genetic variations within 10 bamboo species (Bambusa balcooa, B. bambos, B. tulda, B. vulgaris, Cephalostachyum pergracile, Dendrocalamus brandisii, D. giganteus, D. hamiltonii, D. strictus and Ochlandra travancorica) were collected from TBGRI bamboosetum.

Genetic analysis revealed high level of natural genetic variation between individuals in most of the bamboo species.
