Genetic diversity analysis in Plectranthus edulis (Vatke) Agnew populations collected from diverse geographic regions in Ethiopia using inter-simple sequence repeats (ISSRs) DNA marker system.

The ISSR markers used in the present study were effective in revealing extent and patterns of genetic diversity in P. edulis populations. However, it is important to couple them with agro-morphological traits or codominant molecular markers to get more reliable information for use in breeding and conservation. Several of the potential administrative zones we covered are useful for P. edulis diversification and conservation. However, the crop is currently highly marginalized and this led to rapid decline in population size and loss of valuable agronomic traits. To address this challenge, there is an urgent need to take counteractive measures.
