Conteúdo: | A survey on the use of germpasm conserved in Chinese natinal genebankswas conducted jointly by the Institute of Crop Germplasm Resources of the Chinese Academy of Agricultural Sciences (CAAS) and IPGRI in 1998-99. A study was made of the distribution of accessions in the 15-year period from 1984 to 1998, the 10 crops targeted being: rice, wheat, soyabean, maize, cotton, organges, tea, mulberry, cabbage and cucumber. The aim was to determine patterns of germplasm distribution and use, identify constraints to the use of germplasm conserved in genebanks andsuggest how the situation could be improved. This investigation was conducted through a literature review, a questionnaire, a workshop and site visits. The results showed that 178 485 acessions of the 10 targetcrops, including 448 species and 29 subspecies, have been collected inChina, of which 161 979 accessions were preserved in seed genebanks and 16 516 accessions in fiekd genebanks. Over the 15-year period, germplasm distributed by genebanks was used for screening crop germplasm resources (i.e. for characterization and evaluation for desired traits),for breeding, for basic research and for other uses (including direct use in production).
