Enhancing crop resilience through elite pre-breeding lines with key traits for dry direct-seeded rice.

ABSTRACT: Dry direct-seeded rice (Oryza sativa L.; DDSR) is an alternative to transplanted puddled rice (TPR) that enhances water use efficiency and mechanization and reduces labor, greenhouse gas (GHG) emissions, and global warming potential (GWP). To address the limited availability of DDSR-suitable varieties, we initiated a genomic-assisted breeding program to develop such varieties by combining 19 DDSR and biotic stress-related genes/quantitative trait loci (QTLs), that is, anaerobic germination (qAG_9.1, qAG_9.2), early emergence (qEMM_11.1, qEMM_3.1), early vegetative vigor (qEVV_9.1), root hair density (qRHD_1.1), nodal root count (qNR_5.1), culm strength (qCS_1.1), lodging resistance (qLDG_3.1, qLDG
