Combining QTL mapping and transcriptomics to identify candidate genes for cold tolerance during the budding and seedling stages in rice.

ABSTRACT:

Background

Rice, being a thermophilic crop, exhibits high sensitivity to low-temperature stress throughout its growth and development. Consequently, enhancing cold tolerance (CT) has been a paramount objective in rice breeding programs. The budding and seedling stages are particularly susceptible to low-temperature damage, making it crucial to improve CT during these stages to ensure the stable establishment and development of the rice population.

Results

In this study, we exposed the parental lines Nipponbare (NIP) and Searice 86 (SR86), along with their derived 170 doubled-haploid (DH) population lines, to cold treatments during both the budding and seedling stages. Quantitative trait locus (QTL) mapping was performed using statistical indices such as the survival rate at
