To support the genetic resources unit (needed as a base collection and for use in vegetable research) - GC0116SFV

Description
The Genetic Resources Unit (HRIGRU) fulfills all the provisions for a publicly funded 'designated' PGR collection defined in the MAFF Review of UK Policy on the Ex-situ Conservation of Plant Genetic Resources. The HRIGRU contributes towards the UK Government commitment to international genetic resources conservation through the collection and long-term conservation of the gene pool of vegetable crops, namely Allium (onion, leek, ete), Brassica (Brussels sprout, broccoli, cauliflower, etc.), Daucus (carrot), Raphanus (radish), Lactuca (lettuce) and minor vegetables (celery, spinach, endive, cress, etc.). These collections will provide current and future research scientists with the broadest possible range of working material. Conserved accessions will be monitored for viability and regenerated when seed weight or viability fall. A database management system will store stock control and characterisation data. The GRU will continue to play an active role in the Eurovean Cooperative Programme Allium Brassica & Umbellifer networks.
Objective
1. To maximise the longevity of genetic resources collections of the cultivated forms and wild relatives of Allium, Brassica, Daucus, Raphanus, Lactuca and minor vegetables (celery, spinach, endive, cress, etc.) in collaboration with international agencies and crop networks, by using the recommended international storage standards (IPGRI/FAO) for seed packaging, seed moisture content (5%.) and storage temperature (-20°C).
2. To estimate seed viability, initially and periodically from store, using International Seed Testing Association standard germination test methods.
3. To regenerate accessions of low seed weight or poor germination on a priority basis; for outbreeding taxa (Brassica, Daucus & Raphanus) using fly pollinators in insect-proof cages to effect seed production whilst maintaining population integrity.
4. To characterize accessions using the minimal characterisation descriptors agreed by ECP/GR crop working groups.
5. To maintain passport, stock and characterisation data in a database management system.
6. To utilize the data to assess the composition of each crop/wild collection in comparison with the known geographical distribution and localised variation of the crop and related species. To fill gaps identified in collections through active involvement in collecting expeditions and international networks.
7. To maintain duplicate security collections of horticultural crop for other gene banks under long-term storage conditions (-20°C).
8. To coordinate the European Cooperative Programme Allium and Umbelliter Working Groups, to maintain, develop and distribute the European Allium database, and play an active role in the European Cooperative Programme Brassica group. To collaborate with the Centre for Genetic Resources Netherlands in the conservation of a global collection of Lactuca.
9. To maintain and distribute strategic differential test collections for use as international standards in applied and pure research, namely Brassica S-allele lines, Brassica European Clubroot Differentials & Lactuca Bremia Differentials; and maintain a safety duplicate collection of the HRI tomato Ailsa Craig Near-Isogenic Lines.
10. To collaborate in the long-term seed storage experiment involving a range of experimental material carried out concurrently at the GRU, University of Reading and the Seed Testing Station Wageningen, The Netherlands. 11. To seed onion doubled haploid lines produced under HH0906 SFV as a strategic resource for future breeding and gynogenic research programmes.
