Abstract

Recent research significantly advances hybrid rice breeding by dissecting the genetic basis of crucial traits. Studies uncover Quantitative Trait Loci (QTLs) for yield, disease resistance, drought tolerance, and grain quality, enhancing hybrid vigor and consumer acceptance. Investigations into phosphorus and nitrogen use efficiency aim to reduce fertilizer reliance and environmental impact. Breakthroughs in genomic prediction, integrating genotyping-by-sequencing and Machine Learning, streamline the selection of superior lines and optimal hybrid combinations, accelerating development. Understanding Cytoplasmic Male Sterility (CMS) systems further refines seed production. These efforts collectively bolster sustainable agriculture, food security, and efficient hybrid rice cultivation.
