    Abstract

    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.
