Abstract: The objective of the present experiment was to select the physiologically efficient genotype(s) on the basis of morphophysiological and biochemical characteristics in some elite germplasm lines earlier identified as drought tolerant based on pod yield during the year 2014-15. These genotypes were as follows: ISK1 2009-5, INS 2008-1, TVG 0602, ISK 2008-9, ISK 2009-19, ICGV 95386, ISK 2009-7, 0916, ISK2 2008-10, ISK 2008-18, VG 420 and ADRVT 1. Twelve genotypes were tested with three check high yielding varieties. Data were recorded on plant height, number of branches per plant, leaf area, total dry matter, photosynthetic rate (Pn), transpiration rate (E; mmol m-2 s-1) and stomatal conductance (µmol H2O m-2 s1), days to first flowering, days to 50% flowering, Number of flowers per plant (Nos.), No. of pods per plant (Nos.), fertility co-efficient and pod yield (kg/ha) and protein content. Some of the genotypes showed high values for multiple physiological traits. Interestingly, only two genotypes, ISK12009-5 and ISK12009-5, showed high values for all the physiological traits. These two genotypes could be used in groundnut crop improvement programme for yield enhancement as well as in stress tolerance.
