| Abstract | The genetic variation of 70 individual samples of Casuarina equisetifolia (L. Johnson) subsp equisetifolia and C. equisetifolia subsp incana growing along the northern coast of Senegal was analyzed with RAPD markers. Of the 160 primers tested, five were chosen; they generated 1396 reproducible bands and 61 polymorphic bands that were scored. This result showed a narrow genetic variation among (4.36%) and within (5.90%) C. equisetifolia subsp equisetifolia and C. equisetifolia subsp incana plantation sites. The genetic variation at each site revealed a high degree of polymorphism in Potou (5.90%) and low diversity in Retba (3.06%). In the dendrogram analyses, each sampling site was formed by two main groups. Similar results were found for the dendrograms based on the RAPD data gathered from the five different sites. These dendrograms revealed several polytomies in one of the subgroups, suggesting replication of the same specimens in different sites along the Senegalese coast. The RAPD data support the hypothesis that these populations are of the same provenance, subject to hybridization and inbreeding depression. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
