Pre harvest sprouting in groundnut (Arachis hypogaea L.) seeds belonging to sub species fastigiata is undesirable, since it leads to substantial loss of seeds, both in quantity and quality. This study was conducted to determine the inheritance of fresh seed dormancy in mapping population of TAG 24 x GPBD 4, where in 268 RILs developed from this mapping population. Freshly harvested seeds of mature pods from these RILs were assessed for this dormancy by paper towel test method in laboratory.  In the mapping population developed from TAG 24 x GPBD 4, the chi square (c2) test was not significant for the deviation from the expected 3:1 (dormant: non-dormant) ratio. Here it fitted in the 15:1 (non-dormant: dormant) ratio at 14 days after harvest (< 70%). This study showed that seed dormancy in this mapping population was controlled by duplicate recessive gene.
