| Abstract | The present study was carried out at Horticultural Research Station, Mandouri, Bidhan Chandra Krishi Viswavidyala under New Alluvial Zone of West Bengal, India. The experimental, material comprised of 33 genotypes of bitter gourd, were collected from NBPGR, Thrissur and different parts of West Bengal which were sown at RBD with three replications to study the genetic variability, to assess the genetic divergence for Selecting parental materials for crossing, to estimate heterosis, combining ability and gene action for different quantitative characters with the following objectives. To characterize bitter gourd genotype based on qualitative and quantitative traits as per minimal descriptors. To determine the genetic variability parameters for important growth and fruit characters influencing yield, their interrelationships and their direct and indirect effects on fruit yield. To analyses the genetic divergence of collected materials based on some important quantitative traits. To assess the extent of heterosis in the desired direction and to estimate the dominance reactions for yield and its components and quality parameters. To determine the nature of gene action for yield and other important attributes to identify good combiners, as well as to frame the breeding strategy for the genetic improvement of such characters. Thirty-three bitter gourd genotypes exhibited a wide range of variations in twenty- one qualitative trait and twenty quantitative traits. Two genotypes Gangajali Karala and IC-541448 were found most promising in respect of fruit yield per plant and nutritional quality traits at the Gangetic plains of West Bengal. These two genotypes could be tested at the state and national levels before releasing as varieties. High, GCV coupled with broad-sense heritability, and the genetic advance was registered for the number of primary branches, fruit yield per plant, and beta carotene content, which might be under the control of additive gene action and could be improved upon by selection without progeny testing. Emphasis should be given on fruit weight and petiole length for selecting high yielding genotypes of bitter gourd. |

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.
