摘要：

Cold tolerance is essential for rice cultivation in northern regions, where low temperatures limit yield potential. This study explores the cold tolerance mechanisms in Liyouyuchi (LYYC), an indica hybrid rice developed by crossing Ruifeng S with R1053, LYYC demonstrated superior cold tolerance, outperforming local varieties with a 16.5 % yield increase in Harbin and a yield of 12.35 t/ha in Jilin in 2023. Under cold stress, LYYC exhibited a lower levels of reactive oxygen species (ROS) accumulation and significantly higher survival rate compared to its parental lines. Genetic analysis identif...
