| Abstract | An assessment of genetic diversity studies was undertaken to understand the level and pattern of diversity in 65 mango (Mangifera indica L.) genotypes of India including 20 commercial cultivars, 18 hybrids, 25 local genotypes and two exotic cultivars based on qualitative and quantitative fruit characters as well as RAPD and ISSR profiles. A considerable variation was observed in respect of three important qualitative characters namely table quality, fruit attractiveness and storage life of ripe fruits and potentially superior genotypes for the above traits were identified. A wide variation was noticeable regarding metabolite composition of pulp of ripe mango fruit with respect to total soluble solids, total sugar, reducing sugar, acidity, sugar:acid ratio, ascorbic acid and phenolic content. Fifteen RAPD primers yielded 27 monomorphic and 129 polymorphic bands with percent polymorphism averaging 82.7%. Of a total 70 ISSR bands generated from eight ISSR primers, 60 bands (85.71%) were found to be polymorphic. Cumulative band data from these two methods precisely arranged accessions into eight clusters which correspond well with their pedigree relationship. UPGMA dendrograms drawn using RAPD, ISSR and cumulative data showed highly similar grouping of genotypes on the basis of their parental origin. No clear-cut geographical separation was revealed among East, West, North and South Indian mango cultivars by neither of these molecular markers nor their combinations. This supports the common gene pool origin of mango as well as operation of similar selection pressure as the cultivar preferences in these areas are largely similar. |

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.
