摘要

Seeds stored for a long time may be difficult to germinate under standard conditions and are thus considered not to be viable. By using conductivity test an accession of Brassica rapa L. ssp. rapa with viable seeds was identified among seed material previously declared dead based on traditional filter paper germination tests. The identified accession was germinated by means of long time germination on aseptic agar based growth medium. After transplanting, weaning and vernalisation 0.8% of the seeds could be grown to plants, which flowered and produced seeds..
