Found this interesting and readable pdf whilst searching for something entirely different as usual , how to store seed from a gene bank perspective , different options and the numbers involved in an acession.

How many seeds should be packed?
The number of seeds to be packed for storage will depend on the species being conserved and how often seeds will be removed for monitoring, distribution or regeneration.
The FAO/IPGRI (1994) recommend that for Genebank Standards material which shows little morphological variation ,(genetically homogenous accessions) 3000 seeds are acceptable, but 4000 seeds are preferable to represent each accession.
For materials showing large morphological variation (genetically heterogeneous accessions), an accession should consist of at least 4000 seeds, but 12 000 seeds are preferred.
