| Abstract | Double flowers are valuable floral traits in most floricultural plants. We recently revealed that a double-flowered mutant of Gentiana scabra was caused by an insertion of a retrotransposable element (Tgs1) into GsAG1, one of the C-class MADS-box genes in gentian. In this study, we developed a PCR-based molecular DNA marker to distinguish double- and single-flower phenotypes at the young seedling stage in Japanese gentian plants. To test the validity of the markers, 17 F$_{2}$ populations were produced by selfing F$_{1}$ plants crossed between the double-flower mutant and seven breeding lines. Multiplex PCR demonstrated that the Tgs1 insertion in GsAG1 cosegregated with the double-flower phenotype in two F$_{2}$ populations, indicating that the PCR-based DNA marker was useful to discriminate between double- and single-flower phenotypes in advance of flowering in Japanese gentian. Given that Japanese gentians lack variation in flower shape and require a long breeding period, the DNA marker developed here will be helpful for efficient breeding of double-flowered cultivars in the future. |

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.
