Twenty seven crosses generated in a line x tester fashion using 9 and 3 genotypes as a female and male parents were evaluated to study the extent of heterosis for dry pod yield and yield attributing characters in groundnut. Most of crosses showed significant heterosis over better parent (BP) and standard heterosis (SH) with undesirable direction may be attributed to non-allelic interaction with the large number of decreasing alleles for all the characters under studied. The cross combinations, AG-2245 x ICGV-95070 and AG-1 x ICGV-97079 exhibited significant and positive heterobeltiosis (35.74 %) and standard heterosis (24.81 %) with mean performance of 17.64 gm. and 19.87 gm. for dry pod yield per plant. This two crosses also showed its heterotic effect for kernel yield per plant and number of mature pods per plant, respectively. Superior segregants with this crosses may be selected for further improvement in the pod yield and its contributing traits.
