Germplasm storage

The most economical and efficient medium for germplasm storage is seeds. But, the technique is less efficient or sometimes doesn’t work in case of crops producing sterile or highly heterozygous seeds. It’s also not useful for plants that loose viability after a short period of time.

The best solution to the mentioned problem is the use of meristem tips to serve the purpose. It’s because they are less differentiated and produce identical progeny. Also, because they can produce pathogen free plants at higher frequency and better withstand freezing injury.
