Fresh seed dormancy in bunch type groundnut has a significant influence on pod yield, oil and protein quality. It is required to avoid economic loss in the form of in-situ germination during unpredictable rainfall at maturity. A study was carried out using 32 bunch type groundnut genotypes and 5 groundnut cultivars to identify fresh seed dormant genotypes. Analysis of variance revealed that significant genotypic differences for germination percent. Character Association studies showed that significant correlation coefficients between duration of fresh seed dormancy and intensity of fresh seed dormancy. The result observed that five groundnut genotypes viz., TG-26, ICGV-13558, ICGV-13214, ICGV-13237, ICGV-8110 had more than four weeks duration of fresh seed dormancy and highest intensity of fresh seed dormancy during 2018 season. Therefore, these genotypes were identified as new sources of fresh seed dormancy and could be used as donor parent in breeding programme to develop high yielding bunch type cultivars with 2-3 week fresh seed dormancy in groundnut.
