| Abstract | Mulberry is the sole food source for mulberry silkworm and a number of indigenous and exotic varieties are used in sericulture. Studies on assessment of genetic diversity have been done amongst a few mulberry varieties using one or at the most two methods. However, no comprehensive study on a large number of varieties has been carried out. In present study, single primer amplification reaction (SPAR) methods have been used for determination of diversity in 27 mulberry varieties (exotic as well as indigenous), using four minisatellite core sequence primers for directed amplification of minisatellite DNA (DAMD), three simple sequence repeat (SSR) motifs as primers for inter simple sequence repeat (ISSR) and 20 arbitrary sequence decamer primers for random amplified polymorphic DNA (RAPD) reactions. The Jaccard coefficients were determined for the DAMD, ISSR and RAPD band data (total of 58, 39 and 235 bands respectively). All three methods revealed wide range of distances supporting a wide range of mulberry genetic diversity. A cumulative analysis of the data generated by three methods resulted in a neighbour-joining (NJ) tree that gave a better reflection of the relatedness and affinities of the varieties to each other. Comparison of the three methods by marker indices and the Mantel test of correlation indicated that though all methods were useful for the assessment of diversity in mulberry, the DAMD method was better. When considered as two groups (10 exotic and 17 indigenous varieties), the mulberry varieties in the exotic group were found to have slightly greater diversity than the indigenous ones. These results support the concept of naturalization of mulberry varieties at locales distant from their origins. |

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.
