籽粒苋优异性状相关基因的发掘利用研究进展

为了拓宽籽粒苋基因资源，本研究归纳了籽粒苋在作物分子育种中的作用，包括籽粒苋品质、抗性、高产、节水特性及相关基因的克隆和利用；籽粒苋的富钾特性及富钾基因型筛选；籽粒苋富镉特性及在土壤修复中的应用潜力。认为随着现代种植业的设施化、机械化、集约化，农作物种类和农作物品种的多样性减少，特有基因资源容易流失，遗传基础日益贫乏。开拓、保护、利用籽粒苋这一新型的基因资源，对于农作物品种设计和分子育种具有重要意义。

Progress of Exploration and Utilization of Excellent Traits and Related Genes in Grain Amaranth

In order to broaden grain amaranth genetic resource, this article summarized the role of grain amaranth in crop molecular breeding, including the quality, resistance, high yield, water saving characteristics, and the clone and use of relative genes; rich potassium properties of grain amaranth and rich potassium genotype screening; Cd-rich characteristics of grain amaranth and potential application in soil remediation. Believe that with facilitation, mechanization, and intensification of modern farming, crop species and crop varieties diversity had been declining, the unique genetic resource was easily lost, the genetic basis was increasingly poor. The development, protection and utilization of grain amaranth, a new type of genetic resource, would have important significance for variety design and molecular breeding of crops.
