Viewing the Development of Rice Quality Breeding from Changes of the Standards for High Quality Rice in China

YANG Yi-shan~(1,2), CHEN Li-yun~2, XU Yao-wu~3 (1.Hunan Hybrid Rice Research Center, Changsha, Hunan 410125, China; 2. Hunan Agricultural University, Changsha,Hunan 410128, China; 3. Hunan Yahua Seeds Co. Ltd, Changsha, Hunan 410001, China)  
Comparison was conducted between the two most widely used standards for high quality rice NY 122-86 and GB/T 17891-1999 in rice production in China. It was held that NY 122-86 had too many grain quality indices, and some of them had too high a standard to be achieved in the breeding practice, but GB/T 17891-1999 had the superiority of relatively centralized grain quality indices, close link to breeding practice and good maneuverability. Taking the issue of the two standards as the turning point, the developmental process of rice quality breeding in China could be divided into three stages, i.e., beginning, integrated quality improving and target-oriented stages. Based on the rice breeding practice, the developing tendency of the rice quality breeding in China was also discussed in the paper.
