GISP: Online data management system for pigeonpea germplasm

Germplasm Information System for Pigeonpea (GISP) addresses the data management need by producing a online user-friendly menu driven system that allows users to store, modify and update germplasm information. System has two basic functional modules viz., Germplasm Data Management Module, Germplasm Reports Module. Presently, the database contains information on 1058 accessions (221 early and 837 late maturing lines) evaluated for 22 important descriptors (11 qualitative traits and 11 quantitative traits) for each accession. Statistical analysis of the data was done on the variable with continuous variation to determine the mean, range, variance standard deviation, skewness and kurtosis. Total 4 main reports have been designed to enable quick and accurate retrieval of data viz., Qualitative Report, Quantitative Report, Query-based Report, and Details report. Passport, characteristic, and evaluation data on available germplasm can bere viewed and retrieved through the use of a menu-driven system. Crop breeders can use these data to determine the existence of germplasm that could be useful in their research programs. Requests for germplasm then can be created and forwarded to the appropriate germplasm maintenance site.
