| Abstract:
Agriculture in Taiwan is based on a limited number of recent cultivars. Genetic diversity of plants is the basis of crop improvement. Most cultivars of horticultural crops such as vegetables, fruits, and ornamentals are renewed rapidly, thus the local varieties, older cultivars, wild relatives of crops, and some alien species were replaced and disappeared. These plant materials may have disease resistance or environment tolerance and may be a precious genetic resource for cultivation or breeding in the future. In view of the long term needs of mankind, the preservation of plant germplasm and the construction of a related information system are of importance in each country. More than 40,000 accessions of horticultural crop germplasm have been conserved in the Plant Genetic Resources Center and seven repository gardens in Taiwan. In order to strengthen regional collaboration, to accelerate the exchange and share of genetic resources for academic research, a user-friendly information system of plant germplasm was established. This information system employs ORACLE as a relational database management system set up by using UNIX operation system of HP database server. Users from all over the world can search data through the following website http://www.npgrc.tari.gov.tw. Three-type of related data including passport, characterization and image data of horticultural plant germplasm were stored in our database. The passport data record the background of germplasm, such as scientific name, pedigree, donor or collector, location of collection, criteria of distribution, etc. The characterization data record the characteristics of germplasm, such as horticultural traits, resistance and tolerances to stress, chemical composition, etc. The image data provide photographs of plant germplasm for scientists to differentiate genetic material from possible duplications and for researchers to familiarize with the germplasm rapidly. | |
