An experiment was conducted to evaluate 200 green gram germplasm accessions along with five check entries for drought tolerance using augmented design during summer 2015 by imposing drought stress condition. Observations were recorded on 17 quantitative traits. ANOVA revealed high significant differences among germplasm accessions for yield and for drought tolerant physiological traits. Mean squares attributable to ‘Genotypes vs check entries’ were significant for all the traits except relative water content. Principal component analysis was carried out for 6physiological traits showing positive correlation with yield. Out of 6 factors generated by PCA, there are only 2 factors with eigenvalues more than or close to one contributing for more than 88.03 % of variability. Among the variables studied, variable proline content (11.91) had highest per cent contribution to the total variability followed by spad chlorophyll meter reading (10.80), leaf water potential (10.75), Relative water content (8.51) and specific leaf area (6.31).
