| Abstract | The morphological, cytological and molecular analyses of the plants regenerated after PEG-induced fusion between mesophyll protoplasts from the dihaploid potato clone H-8105 and the wild tuberous disease-resistant species S. pinnatisectum, were performed. A single fusion experiment yielded 313 calli, although only two calli produced shoots. From the rooted shoots, two stable clones (PT-01-1 and PT-01-2) exhibiting different vigor and habitat, were developed. The plants of PT-01-1 clone grew slowly in vitro, produced tubers after transfer to soil but did not set flowers. In contrast, the plants of the vigorous clone PT-01-2 produced both tubers and flowers after transfer to soil. The flower and tuber morphology of PT-01-1 and PT-01-2 regenerants was intermediate in comparison to the parental species. Cytological analysis revealed that the PT-01-1 clone was pentaploid and the PT-01-2 clone was tetraploid. The molecular (RAPD) analysis confirmed hybridity of both clones. The preliminary tests on late blight resistance of the hybrids showed no differences with a potato parent. |

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.
