Abstract
A pot experiment was conducted for screening of ten drought tolerant groundnut (Arachis hypogaea L.) genotypes. Ten genotypes were collected from the International Crop Research Institute for Semi Arid Tropics (ICRISAT), India. Plants were grown in Hoagland solution and by adding 4% polyethylene glycol-6000, water stress was imposed. As index of drought tolerance, change in free proline content and stability of nitrate reductase activity in the leaves of water stressed plants was monitored. In the drought tolerant plant, the increase in proline over the control varied from 5.44 to 7.16 fold and the decrease in nitrate reductase activity ranged from 4.97 - 6.69%. On the basis of increase in proline accumulation and degree of stability of nitrate reductase, 3 genotypes were selected as drought tolerant and they were 3203, ICGV-93269 and ICGV-93232
