Summary

Seeds of two onions (Allium cepa L.) cultivar Pusa Red and Pusa White Flat were studied for their ability to produce normal plants after storage for 18 months at -20 and -180 deg C (vapour phase of liquid nitrogen). These seeds maintained uniform speed, viability, vigour and low frequency of aberrations in comparison to control maintained at room temperature where significant decline in viability occured. A marginally higher level of aberrations occured at -20 than at -180 deg C. Storage under cryopreservation prevented loss of vigour and also reduced aberration frequencies.
