Development of nutritious rice with high zinc/selenium and l

发布时间：2023-02-01 13:02

　　Enriching zinc（Zn） and selenium（Se） levels,while reducing cadmium（Cd） concentration in rice grains is of great benefit for human diet and health.Large natural variations in grain Zn, Se, and Cd concentrations in different rice accessions enable Zn/Sebiofortification and Cd-minimization through molecular breeding. Here, we report the development of new elite varieties by pyramiding major quantitative trait loci（QTLs） that significantly contribute to high Zn/Se and low Cd accumulation in grains. A...
