| Abstract | Edible banana and plantains of the Musa genus are important staple food crops cultivated in humid tropical and subtropical climatic zones. These crops are important for subsistence farming in rural communities and also to generate significant employment and income. In an effort to increase the genetic variability of available cultivars, indexed accessions have been introduced into a regional collection in southeastern Mexico, through the Banana Bioversity International Program. The aim of this study was to use the fluorescently labeled sequence-related amplified polymorphism (SRAP) molecular marker system to characterize the genetic variability within 71 accessions of the existing collection and resolved uncertainties for the better management of the collection, as a preliminary step to establishing a breeding program. These accessions, which included wild species and cultivars of different subgroups, were consistently identified and separated by SRAP markers. A total of 330 polymorphic bands were detected using 12 primer combinations. The average number of polymorphic bands per primer pair was 27.5. The genetic similarity between accessions ranged between 0.44 and 0.97, as estimated using Jaccard's coefficient. Moreover, SRAP marker system probed to be useful to identify closely related accessions in the genus Musa and facilitated the recognition of duplicates to be eliminated and clarified uncertainties or mislabeled banana accessions introduced to the collection. |

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.
