Views on Several Problems in the Grain Quality Improvement of Early Indica Rice of the Yangtze River Valley

DENG Hua feng 1, SHU Fu 1, PU Hong tie 2 (1. Hunan Hybrid Rice Research Center, Changsha, Hunan 410125, China; 2. Zhongfang County Seed Company, Huaihua, Hunan 418000, China)  
The feasibility of grain quality improvement of early rice, possibility of the combination of high yield and fine grain quality and the technical approaches to improving the grain quality of early rice were discussed. It is thought that grain quality characters are mainly controlled by genetic genes, but they are also influenced by ecological conditions, to which different varieties show different sensitivity. The improvement of grain quality in early rice could be achieved by developing varieties insensitive to environmental conditions in grain quality characters. It is also thought to be possible to develop rice varieties with both high yield and fine quality for not all of the grain quality characters are contradictory to high yield. Furthermore, the technical strategies were suggested for improving the grain quality of early indica rice.
