## Abstract
The development of rice seedlings stressed by drought and salt is shown by different morphometric and colorimetric traits.These distinctions can be used to understand the response of plants to challenging conditions.Therefore, this study aimed to assess the efficacy of image-based phenotyping in the early testing of rice plants and observe how the plants respond to both drought and salinity.A stress tolerance index with multivariate analysis was used for the selection of the most important traits.The experiment consisted of 2 factors, namely the degree of environmental stress and rice genotype.Furthermore, the degree of environmental stress comprised normal (NaCl and PEG 0%), drought (10% PEG), salinity (60 mM NaCl), as well as a combination of moderate drought and salinity (5% PEG + 30 mM NaCl).The results showed that both morphometric (area, convex hull, bounding area, perimeter, centermassy) and colorimetric (CIVE, VARI, RGBVI, MGRVI, NDI, GLI, NGRDI) can be used as selection characters.
