Corresponding Author. Masatoshi Funabashi. In addition to these inconsistencies, according to the allozyme results, geographic range and breeding system accounted for the largest proportion of genetic variation at the species and population levels, respectively [21]. Genetic Diversity in Plants. Research on plant genetic resources has a tradition in Witzenhausen. the evolutionary requirement for genetic diversity through the generation of novel allelic arrays via crossing-over, a process which generates recombinant chromosomes. Several methods for estimation of ge- netic diversity using molecular markers are available. 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. ������|��j�����sߑ��Ƿ�{�C��ݟ-� � z� Selection is based on the relative economic importance of these plants on the medicinal and pharmaceutical levels.

Also, plant populations that are less genetically diverse may be more susceptible, in some cases, to pathogens or other environmental stresses. Assessing genetic diversity in plants has involved increasingly sophisticated approaches, from early allozyme work, to amplified fragment length poly-morphisms (AFLPs), and microsatellites.

In addition to these inconsistencies, according to the allozyme results, geographic range and breeding system accounted for the largest proportion of genetic variation at the species and population levels, respectively [21]. Genetic Diversity in Plants. Research on plant genetic resources has a tradition in Witzenhausen. the evolutionary requirement for genetic diversity through the generation of novel allelic arrays via crossing-over, a process which generates recombinant chromosomes. Several methods for estimation of ge- netic diversity using molecular markers are available. 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. ������|��j�����sߑ��Ƿ�{�C��ݟ-� � z� Selection is based on the relative economic importance of these plants on the medicinal and pharmaceutical levels.

Also, plant populations that are less genetically diverse may be more susceptible, in some cases, to pathogens or other environmental stresses. Assessing genetic diversity in plants has involved increasingly sophisticated approaches, from early allozyme work, to amplified fragment length poly-morphisms (AFLPs), and microsatellites.
