Abstract:

Quinoa (Chenopodium quinoa, Willd.) as a new health food in the 20th century, its comprehensive nutritional composition, stress resistance and other characteristics have been paid much of attention, and enjoys the reputation of “nutritional gold”, “vegetarian king” and “food in the future” in the world. In recent years, with the rapid development of genomics and high-throughput sequencing technology, the high-quality whole genome sequence of quinoa has been completed, and the omics analysis and functional research of a series of key genes have been gradually carried out. In this review, we summarize the research progress in quinoa genomics, gene family analysis of important transcription factors, genetic map construction, QTL mapping of important traits, and genes for important agronomic and yield traits. Moreover, according to the current status of quinoa breeding, this paper also put forward five key problems in quinoa breeding, and pointed out four important directions of genetic improvement and breeding of quinoa in the future, so as to provide reference for the realization of directional genetic improvement of quinoa in the future.

Key words: quinoa, genomics, genetic breeding, traits, genes
