Abstract:273 peanut germplasm resources were cultivated under simulated drought- stressed condition ingreenhouse. Seven morphologic indexes were tested for all varieties, which included fresh weight of above ground,fresh weight of below ground, fresh R/T, dry weight of above ground, dry weight of below ground, dry R/T, length ofmain stem. Principal component analysis was performed by relative drought resistance coefficient on the seven indi-cators. The results showed that relative fresh weight and relative dry weight of below ground had the maximumweight in values, which were used as the main indices for evaluating and ranking the drought-resistant capabilitiesof 273 peanut materials. Five groups of drought-resistance capabilities of these peanut materials were detectedbased on Principal Components Analysis, i.e., 8 germplasm resources were highly drought-sensitive, 46 germplasmresources were drought-sensitive, 188 germplasm resources were medium drought-resistant, 24 germplasm resourc-es were drought-resistant, and 7 germplasm resources were highly drought-resistant.
