Abstract: Genetic diversity is one of the three forms of biodiversity recognized by the World Conservation Union ( IUCN ) as deserving conservation. �L�%pO�&���*C"*)D���ZU��v bj�G6��s�X����C��e��I�Ov^�L ��5_\>�]7��t��_q+�%�䍬K0�U8�+����Ǎ��|u�I�8��3��Nm3�S��"��X�~ΐ���{���&�����K7. "Genetic material" means any material of plant, animal, microbial or other origin containing functional units of heredity. Conservation of genetic diversity is essential to the long-term survival of any species, particularly in light of changing environmental conditions. 0000003597 00000 n 1,2, Boniface B.

Finally, the need for a sustainable and integrated approach to the conservation of botanical diversity is Efficient Conservation Of Crop Genetic Diversity.

Fast Download speed and ads Free! xref Genetic resource conservation is widely acknowledged as important. Biodiversity refers to variation within the living world, while genetic diversity represents the heritable variation within and between populations of organisms, and in the context of this paper, among plant species. eir rich genetic diversity needs to be exploited in conservation and breeding programme. This pool of genetic variation within an inter-mating population is the basis for selection as well as for plant improvement. Metrics of diversity are also relevant for conservation, as populations with high levels of genetic diversity are expected to exhibit longer persistence, as there is more standing variation for selection to act on (Table 2; Hoffmann et al., 2015; Reed and Frankham, 2003).
