| Cold is the most important abiotic factor that affect rice yield in Chile, which can alter the phenology and physiology of the rice at seedling stage. With the aim to increase the accuracy for cold tolerance evaluation in Chilean Rice Breeding Program of the Instituto de Investigaciones Agropecuarias (INIA), 109 experimental lines were evaluated to cold tolerance using morphological and physiological traits, at seedling stage. Cold treatment was achieved by placing seedlings at 5 °C on dark for 72 h and evaluations were made after seven days recovery. Leaf chlorosis based on the standard evaluation system scale (SES), Chlorophyll content (Chl), Malondialdehyde concentration (MDA) and maximum quantum yield of Photosystem II (Fv/Fm) were evaluated.
