摘　　要：微营养不良是全世界,特别是发展中国家最主要的营养问题之一。本文简述了稻米中微营养的含量及分布;采用提高绝对含量及增加其生物有效性两种策略,综述了开展富含微营养水稻育种的进展,包括富微营养水稻的常规育种、诱变育种及转基因育种;指出水稻微营养育种的局限性及解决途径。Mieronutrient contents and distribution in rice grain was briefly summarized in this paper. Advances in micronutrients breeding including traditional breeding, induced mutation, and transgenic breeding were reviewed based on two strategies ： increasing the content and the bioavailability of micronutrients. The problems and suggested solutions for improving micronutrient in rice breeding were discuss.
