Establishing breeding trends of irrigated rice cultivars in the upstream of the Yellow River Basin employing the China National Rice Research Institute Database

Abstract

We elucidated the rice development trends in the Ningxia Autonomous Region, the major irrigated rice cultivation area in the upstream region of the Yellow River, employing the China National Rice Research Institute database. We were able to identify the type of varieties and some distinctive tendencies. From 1979 to 2020, amylose content in rice varieties reduced, whereas stock heights, fertilizer application, and growing periods increased. The growing period trend was inconsistent with the national goals. Low amylose content may characterize the tendency of the tastes of consumers. The influence of global warming was also considered. Varietal development trends did not facilitate a decline in the environmental load and may also influence climate change adaptation.
