摘 要:摘 要:微量营养元素缺乏又称“隐性饥饿”,已经成为全球最普遍的公共健康问题,尤其是对于发展中国家的妇女和学前儿童。锌是人体必需的微量营养元素,培育和推广富锌作物品种是减少贫困地区锌缺乏的有效手段,国际生物强化项目(HarvestPlus) 在这一领域处于全球领导地位。介绍了HarvestPlus 项目的发展历程,总结了国内外锌生物强化的最新进展,并结合CIMMYT 开展小麦锌生物强化育种的实例,对育种中相关问题进行了探讨。
Abstract: Abstract: Micronutrient malnutrition, the so-called hidden hunger, affects more than one third of the world’s population, especially women and preschool children in developing countries. Zinc is an essential trace element for humans. HarvestPlus is a global leader in reducing zinc deficiency by breeding zinc-enriched crops, which are accessible to remote resource-poor people. In this paper, we reviewed the starting and three developmental phases of the HarvestPlus program, the latest progress on zinc biofortification, and the breeding practice in CIMMYT for zinc-biofortified wheat cultivars. The issues related to biofortification breeding were also discussed.
