Carbon isotope discrimination (a trait correlated with water use efficiency) studies were made in 21 F 1 hybrids of groundnut. Lower values of Carbon isotope discrimination (Δ) were recorded in TMV2-NLM, ICG 2716, Tirupati 1 and ICGV 86031. As many as eleven hybrids with one of these as parents had lower Δ), values, the best being ICG 2716 x TMV2-NLM and Trirupati 1 x TMV2-NLM. ICG 2716 x TAG 24 exhibited significant negative heterosis over mid parent while TAG 24 x TMV2-NLM had significant positive heterosis over better parent.
