In the present investigation, twenty F1 crosses along with nine parents (5 lines and four testers) were evaluated for 23 yield, yield components and stem rot resistance during rabi, 2019 in order to assess the per se performance of parents and crosses under sick plot and control condition. Analysis of variance for all 23 yield, yield components and stem rot resistance revealed that mean sum of squares due to treatments were highly significant for all characters investigated. Among parents, the line ICGV-07262 and tester J-11 and CS-19 were registered as the best performers as they outperformed desirable per se performance for most of the yield and yield components together with stem rot resistance under sick plot and control condition. Hence, these lines and testers could be considered as a potential parent in hybridization for the improvement of groundnut productivity under sick plot and control conditions. The cross ICGV-07262 × TCGS-1862 recorded as superior cross for most of the yield and yield components and could be exploited in breeding programme to develop high pod yielding stem rot resistant genotypes in groundnut.
