The good-quality rice breeding, was selected good-quality parents for crossing and good rice appearance during breeding process, was started in the late 1970’ decade. Taichung 189, Tainung 70 and Tainan 9 were breeding in this way at that time. The good-quality rice breeding was organized by The Rice Breeding Team, set up according to the policy of Taiwan Province Government, during 1985-1998, was crossed in the Taiwan Research Institute and Taichung District Agricultural Improvement Station and selected in different station during breeding descendants. The yield and rice appearance were the goals of good-quality rice and total 17 japonica, 1 indica, 4 glutinous rice varieties had been released during that time. 9 varieties had been selected by each station before 1985 and 9 varieties had been recommended good-quality rice by government. After 1998, the crossing and selecting of rice breeding are returned to each institutes and stations. Beside rice appearance, the eating quality, detected by AN-800 and MA-30A machines, were the goals of good-quality rice and total 22 rice varieties had been released during that time. 8 varieties had been selected by Taiwan Rice Breeding Team before 1998 and 5 varieties had been recommended good-quality rice by government. The rice appearance and eating quality of new varieties is brtter than that of olds’. After 2006, rice releasing system has been followed The Seeds and Seedlings of Plant Variety Law. The good-quality rice goal is extending to nutrition and alterative utilization. From that time, 19 varieties have been applied in this system. The good-quality rice breeding goals of research institute and stations have been investigated recently. The rank of good-quality rice breeding goals is follow by eating quality ＞ rice appearance ＞ yield or plant type ＞ biological stress tolerance ＞ physiological stress tolerance ＞ storage tolerance.
