| Abstract | Forty white lupin (Lupinus albus L.) landraces were collected from farmers' fields in Egypt. Passport data, including information on cultural practices, as well as data for a few descriptors to assess in situ diversity were recorded. Soils from the collection sites were analysed for physical and chemical properties. White lupin seems to be grown as a minor winter crop all over Egypt, and on a wide variety of soil types, from heavy clay to sandy soils. Many farms growing white lupin had highly calcarious soils with a pH above 8.5, and CaCO3 content in excess of 10%. This finding indicates that resistance to high pH or calcium content may be available in white lupin germplasm from Egypt. Fusarium wilt is the most important pathogen of white lupin in Egypt, but great differences were observed between fields. Local landraces have an indeterminate canopy structure and showed a great variation in plant vigour that could partially be ascribed to soil fertility. Heterogeneous flower colour in most fields suggested that genetic variation exists in the local landraces grown by farmers. Seeds were generally moderately bitter with alkaloid content varying between 0.2 and 1.4%. The local bitter landraces are preferred to imported sweet cultivars. The collection has been stored at the Egyptian Gene Bank. |

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.
