    摘要:

    如何平衡农业生产与环境资源的矛盾是我国乃至全球面临的巨大挑战。为应对这一挑战,我国科学家提出“绿色超级稻”的理念,建立了全基因组育种选择技术体系,挖掘出一批高产、抗逆、优质、抗病虫以及营养高效的绿色性状基因,培育大量绿色超级稻品种并推广应用,推动了作物育种目标和育种模式的转变。本文总结了绿色超级稻的理念、发展历程以及绿色超级稻取得的重要进展,并就绿色营养优质水稻的培育与应用进行展望。

    Abstract:

    How to increase agricultural productivity with less resources and less impacts on the environment has been a great challenge to geneticists and breeders in the all world. Chinese scientists therefore proposed the notion of "Green Super Rice" (GSR) that promotes resource-saving and environment-friendly rice production coupled with increasing grain yield and quality. A large number of functional genes identified for desired traits such as high yield and superior quality, resistance to pests and diseases, tolerance to abiotic stresses, and high nutrient-use efficiency, have provided a rich resource for developing GSR in the breeding programs. Through the novel breeding strategies established with genomic selection and gene-specific selection, a batch of GSR cultivars with multiple desirable genes have been developed and widely adopted in China and other countries. The practices and achievements of GSR have led to a paradigm shift of the goals and models of crop genetic improvement. Here, we review the concept, development and achievements of GSR, and provide perspectives of developing green and nutritious rice cultivars to enhance the development of green agriculture.
