Cold tolerance at early seedling stage of rice (Oryza sativa L.) is one of the major determinants for the stable stand establishment in temperate and high-elevation areas. In the current study, with 269 recombinant inbred lines derived from a cross between a japonica tolerant to cold and a sensitive indica of rice, the cold tolerance at early seedling stage was evaluated by the paper-roll tests in a two-replication trial with 10- and 13-day treatments at 10 degrees C, respectively.
