| Abstract | A study of genetic diversity in Pongamia pinnata representing 33 candidate plus trees (CPT) was undertaken in five agro-ecological zones of Southern Peninsular India. Eleven primer combinations generated 532 bands with an average of 48 bands per primer combination. E-ACG/M-GCC showed the highest polymorphism of 98.80 %. E-ACG/M-GCC, E-CAA/M-CTG, and E-CAG/M-GTG with higher polymorphic information, marker index, and resolving power were found to be effective in detecting unique bands. Nei's gene diversity and Shannon's indices of 0.159 and 0.247, respectively, indicated the presence of high gene diversity in southern dry and transition zones of Karnataka. The inter-population differentiation between zones (G $_{ST}$) was 0.296. The level of gene flow (Nm) estimated was 1.34. Analysis of molecular variance indicated that 44.78 % of variance occurred within the provenance when compared to variations among agro-ecological zones (22.22 %) and among provenances within zones (33 %). Based on un-weighted pair group method using arithmetic averages method, the pongamia accessions were grouped into three major clusters and four sub-groups depending on their geographical locations. The diverse CPT identified in this study could be selected and used for tree breeding, germplasm conservation, and biofuel program in India and other tropical countries. |

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.
