Therefore, it is necessary that restoration aims at achieving high genetic diversity of plant populations in addition to the recovery of characteristic species composition and diversity. Recombination events can result in either reciprocal recombination or the related process of gene conversion. The primary goal of the present study is to ascertain the genetic diversity of B. barna using a number of molecular markers, already established in several plant and animal species. �tq�X)I)B>==���� �ȉ��9.

Assessing genetic diversity in plants has involved increasingly sophisticated approaches, from early allozyme work, to amplified fragment length poly-morphisms (AFLPs), and microsatellites. While the usefulness of molecular tools to describe genetic polymorphisms and the importance of generic resources in agriculture has been largely covered in the literature, we felt the need to highlight how the of genetic diversity in a plant species depends on its evolution and breeding system, ecological and geographical factors, past bottlenecks, and often by many human factors. Assessing genetic diversity in plants has involved increasingly sophisticated approaches, from early allozyme work, to amplified fragment length poly-morphisms (AFLPs), and microsatellites.
