The gene bank at ICRISAT conserves about 15?342 accessions of Arachis germplasm from 93 countries. The germplasm is stored in the form of pods under medium-term storage conditions (4°C and 30% relative humidity). Because pod storage requires more space (×3) the relative costs of pod and seed storage were compared for the cultivars JL24 and ICGS76. Following estimates the cost saving per accession is US$0.59 or about US$9050 annually for the entire collection if the switch is made to seed storage. However, the slightly longer survival due to pod storage results in less frequent regeneration. The cost of regenerating one accession is estimated at US$13.06 for pod storage, increasing to US$13.26 for seed storage due to the extra labour cost incurred for shelling. Assuming an 11 year regeneration interval under both storage methods, the cost of storing and regenerating an accession in perpetuity would be US$62.49 for pod storage and US$47.72 for seed storage when the real rate of interest is 4%.
