摘要：

锌是人体健康所必需的微量元素之一，水稻是世界上主要的粮食作物，稻米尤其是精米中的锌含量非常低，提高稻米锌含量能有效缓解人体锌缺乏症。本文综述了稻米锌含量的遗传变异，稻米不同部位锌的分布模式、遗传模式、QTL定位、基因克隆及育种进展，为水稻富锌分子育种提供重要参考。

关键词: 稻米, 锌含量, QTL定位, 基因克隆

Abstract:

Zinc （Zn） is one of the essential micro-elements for human health. Rice is the main staple food crop in the world, however, the Zn content in rice, especially in milled rice, is very low, thus improving Zn content in rice could effectively alleviate human dietary Zn deficiency. The paper reviewed the progresses on the genetic variability of Zn content in rice, the distribution patterns of Zn in the different parts of rice, the patterns of inheritance pattern, QTL mapping, gene cloning and its genetic breeding, which would provide important references for molecular breeding of Zn -enriched rice.

Key words: rice, zinc content, QTL mapping, gene cloning
