ABSTRACT
Groundnut (Arachis hypogaea L.), a legume crop often grown as a rainfed crop in India subjected to drought at different intensities and duration consequently leading to varied total production of 4.3 to 9.6m tonnes. A study was conducted during kharif and rabi 2011 with advance generations of groundnut cultures surrogating physiological traits with the pod yield. From the study, it was inferred that specific leaf area, chlorophyll content and relative water content can be very well exploited for selecting cultures showing higher water use efficiency eventually having higher pod yield and higher additive gene action controlling these traits.
