Abstract

Biodiversity is the variation of life at all levels of biological organization. One of the important components of biological diversity is the genetic diversity. Genetic diversity refers to the variation of genes or entire genome within and between populations of organisms. Keeping in view the significance of genetic diversity in wild plants, some research articles based on important wild plant genera and species of angiosperms including few rare, threatened, endemic, medicinal and economically important from different regions of the world are reviewed. The genetic diversity of plant species depends on different factors i.e. ecological, geographical, breeding system & anthropogenic effects. High genetic diversity is observed at species level even in small sized population by using AFLP, SSR, & ISSR genetic markers.
