| Abstract | Sugarcane is second most important industrial crop in India. In order to avoid genetic vulnerability of hybrids for new emerging pests or diseases and to design a new sugarcane breeding strategy, it is essential to know the genetic diversity in present commercial hybrids. Randomly Amplified Polymorphic DNA (RAPD) marker was used to detect the DNA polymorphism among 22 hybrids grown in Peninsular and East coast zones of tropical India. Of the 143 fragments generated by 16 RAPD primers, 69 were polymorphic with an average of 4.31 polymorphic fragments per primer. The level of polymorphism observed among these hybrids was 42.6%. Jaccard’s similarity coefficient value recorded between closely related hybrids was 0.951 while lowest coefficient value of 0.727 was detected with distantly related hybrids. The average similarity coefficient among these hybrids was 0.831. Unweighted pair group method with arithmetic averages (UPGMA) cluster analysis divided all these hybrids into two major clusters based on adaptation to agro-climatic conditions. However, hybrids in these clusters divided into subclusters based on their pedigree. Genetic similarity obtained from the analysis could be useful for plant breeders to choose diverse parents for creating more variability and select elite varieties in breeding programmes. |

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.
