中国科学家绘制高地棉花基因图, 提升抗病性和繁殖精度。 Chinese scientists map upland cotton’s genetics, boosting disease resistance and breeding precision.

中国科学家绘制了最详细的高地棉花基因图,确定了69个与纤维质量、产量和抗病性等关键特征相联系的遗传地点,包括新发现地区VWD11,该区对Verticillium的生长产生了抵抗力。 Chinese scientists have developed the most detailed genetic map of upland cotton, identifying 69 genetic loci linked to key traits like fiber quality, yield, and disease resistance, including a newly discovered region, VWD11, that confers resistance to Verticillium wilt. 这项研究使用107种品种的“超级全景”发现,高原棉花源于中美洲的狭小品种,从墨西哥的尤卡坦半岛开始,经历了三阶段的驯化过程,并通过古代混合化获得了适应优势。 Using a "super pangenome" from 107 varieties, the study reveals upland cotton originated from a narrow lineage in Central America, underwent a three-stage domestication process starting in Mexico’s Yucatan Peninsula, and gained adaptive advantages through ancient hybridization. 研究结果有助于准确、有的放矢的育种,推进可持续的棉花生产,并加强中国作为世界顶尖棉花生产国和消费国的地位,从而对全球农业复原力和纺织品供应安全产生影响。 The findings enable precise, targeted breeding, advancing sustainable cotton production and strengthening China’s position as the world’s top cotton producer and consumer, with global implications for agricultural resilience and textile supply security.
