Prospects of utilization of inter-subspecific heterosis between indica and japonica rice
The Asian cultivated rice (Oryza sativa L.) grown worldwide is divided into two subspecies, indica and japonica. It is well known that the heterosis of inter-subspecies is usually stronger than that of intra-subspecies.

Grain yield improvement in high-quality rice varieties released in southern China from 2007 to 2017
In recent years, high-quality rice varieties have been widely cultivated for food production in southern China. However, changes in the yield performance of different high-quality rice varieties are still unclear.
