| Abstract | Quantitative trait locus (QTL) analysis was conducted on three full-sib Pinus elliottii var. elliottii × P. caribaea var. hondurensis (PEE × PCH) hybrid families to identify genomic regions affecting two growth traits, height (Ht) and DBH at age 5, and seven morphological (“form”) traits. The QTL detection population consisted of family A containing 122 progeny, which was related to the validation population family B (n = 66) via a common PEE parent, but unrelated to the second validation population, family C (n = 107). Using a double pseudo-testcross QTL mapping approach, quantitative trait loci (QTLs) had been identified in the detection population for Ht, DBH, and three form traits. One QTL for Ht05 was validated in the shared common PEE lineage. For two other form traits, QTLs were validated by identifying QTLs that co-located to the same genomic regions in both validation populations. Two QTL, for another form trait and DBH05 were not identified in the original detection population but occurred in both validation populations. The QTL positions detected in this study provide a resource to identify form-trait loci using the Pinus genome or expressed sequence tag (EST) sequences, which may be useful for future association studies. |

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.
