Abstract
Giant embryo rice (GMR) is a special rice which can produce eutrophic functional rice. Giant embryo rice and its intensive processing products have been widely used in food, medicine, health care products and other fields, with extremely important scientific significance and economic value. In recent years, a series of important advances have been made in the research of giant embryo rice, and its achievements have attracted the attention of rice breeders and consumers at home and abroad. In this paper, the genetic basis of giant embryo traits and the effects of environmental factors on giant embryo rice were reviewed and analyzed, and the application prospect of giant embryo rice was also prospected, these will provide important reference for genetic improvement and application promotion of giant embryo rice.
Highlights
Rice (Oryza sativa L.) is one of the main grain crops in China
A number of QTLs affecting rice quality traits have been identified in rice (Peng et al, 2014a)
Rice quality traits are affected by environmental factors, such as soil conditions, temperature, day and night temperature difference and sunshine (Ambardekar et al, 2011; Li et al, 2018a)
Summary
Rice (Oryza sativa L.) is one of the main grain crops in China. Rice production accounts for about 40% of the total grain production. Rice quality traits are affected by environmental factors, such as soil conditions, temperature, day and night temperature difference and sunshine (Ambardekar et al, 2011; Li et al, 2018a). The content of protein, mineral and vitamin is higher than that of ordinary rice It has higher antioxidant activity and better nutritional and health functions. Many research groups at home and abroad have conducted in-depth studies on nutrition and quality traits, important agronomic traits, intensive processing of giant embryo rice and efficient utilization of byproducts, and made a series of important new progress (Rathore et al, 2018; Coleman et al, 2018; Fitzgerald et al, 2003; Kang et al, 2011). The genetic basis of giant embryo traits and the effects of environmental factors on mega-embryo rice were reviewed and analyzed, and the application prospect of giant embryo rice was prospected, in order to provide reference for genetic improvement and application promotion of giant embryo rice
