Description Germplasm seed accessions require frequent regeneration for continued conservation and utilization. Regeneration
of diverse crop germplasm accessions is a challenging task for large genebanks. The problem is severe
especially with the wild relatives because of adaptation problems, lack of facilities and seasonal constraints
where genebanks are located. Special facilities were created at ICRISAT Genebank for regenerating all the
seed producing wild species of genus Arachis and unadapted Arachis hypogaea accessions. A total of 304
accessions represented by 41 wild species and 290 accessions of six botanical varieties of cultivated groundnut
were successfully regenerated using these facilities. Much of the problems encountered during field regeneration
especially with the wild species were overcome. Regeneration was possible round the year with minimum
operational interference. The seedling establishment, plant growth and pod yields per cycle were significantly
higher in these facilities. Establishing such facilities by genebanks could be advantages in efficient regeneration
of problem accessions on a long-run for conservation and continued availability of diverse germplasm for
utilization in crop improvement programs.
