In the dual background of ensuring food security and increasing consumer demands for rice quality, in order to cultivate high-yield, high-quality, and widely adaptable varieties, guided by the theory of core germplasm breeding, the author combined traditional pedigree methods, molecular marker assisted selection techniques, and the use of advanced equipment for identification, has bred a new high-quality rice variety Huangsiyuezhan, which is classified as a first-class rice by Agricultural ministry standard(NY/T 83—2017). Huangsiyuezhan has shown ideal plant type, high yield, wide adaptability, resistance to rice blast disease, and excellent taste quality in experiments conducted in different years and regional trial, achieving effective aggregation of excellent genes such as high yield, high quality, and disease resistance. In 2023, Huangsiyuezhan was approved by the Guangdong Provincial Crop Variety Approval Committee. Huangsiyuezhan is suitable for early and late rice cultivation in rice growing areas outside northern Guangdong, and has great potential for promotion.
