来源：农民日报 近日，记者从中国农业大学获悉，该校动物科技学院韩红兵教授团队联合苏州拉索生物芯片科技有限公 司和天津奥群牧业有限公司共同发布了国产首款绵羊固相芯片——"华芯绵羊"，该育种芯片可助力快 速、精准解析我国绵羊遗传特征，为生长性能改良、繁殖和抗病等研究提供坚实支撑，有力推动绵羊精 准育种进入国产化的新阶段。 "除了75K位点的'华芯绵羊Pro'，我们还提供18K位点的'华芯绵羊Mini'，更加适应育种与养殖企业的实 际使用需求。同时，我们'华芯绵羊'从位点标记、芯片设计到芯片扫描仪、试剂、配套软件及算法，均 具有我国完全知识产权，能够确保用户无忧使用。"韩红兵说。（农民日报全媒体记者 杨惠） 据了解，此次发布的"华芯绵羊"育种芯片位点总数约7.53万个，涵盖了绵羊生长、繁殖、体型、肉质、 羊毛、屠宰率等11项重要经济性状。同时芯片具有高效率、低成本、高准确性、高兼容性等特点，能有 效提升绵羊繁育的准确性。 我国是全球羊存栏量和羊肉产量最大的国家，但种业水平与产业发展仍与国外存在较大差距。推动羊的 高效生物育种，实现种源自主可控，是种业振兴的国家战略需求。 基因组选择技术能够实现早期选择，是提高育种效 ...

Core Viewpoint - The introduction of new pear varieties, particularly "Ningli Early Dew," showcases advancements in breeding techniques aimed at enhancing taste, appearance, and cultivation efficiency in the pear industry [1][2]. Group 1: New Pear Varieties - "Ningli Early Dew" is a new pear variety that matures in late June, which is half a month earlier than traditional early-ripening pears, with a growth period of approximately 90 days from flowering to maturity [1][2]. - The variety has a fruit weight of 280-320 grams and features a small core, providing a sweet and juicy taste experience [1]. - Other new varieties presented include "Ning Early Gold," "Ning Late Green," and a red-skinned pear series, all developed by the Nanjing Agricultural University pear innovation team [1][2]. Group 2: Breeding Techniques - The breeding process for new pear varieties traditionally takes 12 to 15 years; however, the research team has implemented image recognition and machine learning technologies to accelerate this process [2]. - The development of the "Cloud Shang Hou Ji" breeding information platform has standardized data collection and improved the efficiency of new pear variety creation [2]. - The combination of hybrid breeding, bud mutation, and molecular marker selection has significantly enhanced the speed and effectiveness of new variety development [2]. Group 3: Market Impact - The newly introduced varieties cover a range of maturity periods from extremely early to mid-late, ensuring a continuous supply of fresh pears in Jiangsu from late June to early September [4].
