“xaxcikix”抢救濒危资源!农xaxcikix业种质资源普查成果超预期

  种质xaxcikix资源是保障粮食和重要农产品稳定xaxcikix安全供给的战略性资源,从2021年起,我国开始了新中国成立以来实施规模最大、覆盖范围最广、参与人数最多的全国农业种质资源普查,农业农村部今天公布,三年多来,普查摸清了种质资源的种类数量、特征特性等家底,新收集了一大批农业种质资源,抢救性保护了一批濒危资源。

  普查期间,全国15xaxcikix0万普查人员,累计行程6300多万公里,普查覆盖了全国31个省份和新疆生产建设兵团。农作物普查包括了前两次未涉及的332个农业县,填补了干旱与高原等特殊生态区、边境及少数民族区域空白。

  坚持查保并举的举措下,普查成果超出预期。

  农作物方面,新收集种质资源13.9万份,覆盖了粮棉油糖、果菜茶桑等,99%为种植历史久远、类型丰富、性状多样的传统地方品种和野生近缘种。

  畜禽方面,全面查清了畜禽、蜂和蚕资源家底,新发现鉴定地方品种资源51个,采集制作遗传材料107万份,同步对61个濒危资源开展抢救性保护,目前159个国家级保护品种都实现了活体保护。找回了曾宣布灭绝的10个品种。

  水产方面,全面摸清了水产养殖种质资源种类、数量、区域分布状况,采集制作遗传材料12万份。

  农业农村部种业管理司司长 刘莉华:进一步加强种质资源收集保护,加快资源精准鉴定,强化资源改良创制,推动资源共享利用,切实把资源优势转化为创新优势、产业优势,为加快加力推进种业振兴打下坚实资源基础。(央视新闻客户端)
