| Abstract | Salt stress is a major limitation for crop production in saline soil. For investigating genetic mechanism of salt tolerance at germination and seedling stage, and improving salt tolerance of sorghum, 181 recombinant inbred lines derived from Shihong137 and L-Tian were used in this study. Quantitative trait loci (QTLs) for three traits at germination stage and nine traits at seedling stage were analyzed. 12 and 29 QTLs were identified at germination and seedling stage, respectively. Only qGP7-1 for germination percentage was found consistently under control and 2.0 % NaCl stress. Other QTLs detected under salt stress were salt specific expression. Six major QTLs were identified, and positive effects were all from Shihong137 except that of qRL10-2. Five chromosome regions controlling more than one trait simultaneously were found under salt stress. The results demonstrated that salt tolerance at germination and seedling stage of sorghum was a complex quantitative trait and controlled by multiple genes. However, six major QTLs and five chromosome regions played crucial role in salt tolerance of sorghum, which could be applied in marker assisted selection and in further investigation for salt tolerance. |

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.
