| Abstract | Species of Aesculus genus are divided into five main sections according to their susceptibility and resistance to horse chestnut leaf miner using molecular markers. Some species of the genus Aesculus are yearly severely infested by horse chestnut leaf miner (Cameraria ohridella). The larvae mine the leaves and under appropriate conditions can damage up to 100% of the leaf area. In this study, we assessed the genetic diversity of eight species of horse chestnut and their genotypes which have varying susceptibility to the leaf miner. Analysis of eight microsatellite loci showed high polymorphic information content 0.45–0.77 (0.60 in average) and high genetic diversity. For each locus, we found on average 5.50 alleles. During three vegetation periods, the leaf area damage of these genotypes was evaluated using the statistical software Assess 2.0. Different pressure of leaf miner and different development at each locality was recorded, and in some cases less damage was found, in one case the lesser damage was permanent. From the data, a pathological scale was established and a dendogram of similarity was created. Based on SSR analysis, four groups of Aesculus trees were distinguished according to their resistance or susceptibility and five main section+Hybrid were found. By cloning and analysing the inner transcribed spacers, the ITS1 and ITS2, inner and inter species variability was examined. For the sequence of hybrid species A. × carnea, no compliance was revealed in NBCI database. For this reason, the first sequence of this genotype was obtained. |

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.
