Abstract

The biomass and seed yield of groundnut (Arachis hypogaea L.) genotypes were affected by elevated temperature of +3°C (eT) and the presence of elevated CO2 of 550 ppm (eT+eCO2) ameliorated these impacts to some extent. K-6 and Narayani are sensitive to high temperature and responsive to eCO2 and K-9 showed better tolerance to higher temperature (>40°C). The eT and eT+eCO2 conditions significantly altered the oil content, saturated and unsaturated fatty acid levels of groundnut genotypes.
