Abstract excerpt

KEY MESSAGE: Integrated QTL GWAS identified three key genes, whose heat ind uction during maize germination was verified via RNA seq and qRT PCR analysis. Heat stress during germination critically impairs maize seedling establishment and yield stability, yet its genetic basis remains poorly understood. Here, 21 quantitative trait loci (QTLs) for heat tolerance were identified in a recombinant inbred line (RIL)...
