在保障粮食安全和消费者对稻米品质要求日益提高的双重背景下,为了培育高产、优质、广适性大品种,笔者在核心种质育种理论指导下,通过将传统系谱法、分子标记辅助选择技术和运用先进仪器设备鉴定相结合的方法,选育出部标(NY/T 83—2017)1级优质稻新品种黄丝粤占。 黄丝粤占在不同年度和不同区域试验中表现出株型理想、丰产性好、适应性广、抗稻瘟病、食味品质优异的特性,实现了高产、优质和抗病等优良基因的有效聚合。2023年黄丝粤占通过广东省农作物品种审定委员会审定,适宜广东粤北以外稻作区作早、晚稻种植,具有很大的推广潜力。

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.
