台湾省粳稻面积种植占90%以上,但粳稻品种不抗褐飞虱.通过把籼稻抗褐飞虱的基因转入粳稻的育种过程,育出了选系Chianung50,成为台湾省第一个抗褐飞虱的粳稻品种.该品种一九八一年六月经台湾稻米改良委员会品种登记小组同意推广,定名为台南68.台南68是嘉义农业试验站于一九七三年,从杂交组合Nankai—yu114×[Naukai—yu77×(台南5号~2×ASD7)的后代选育成的.该品种除了继承ASD7的抗性,在生长后期表现抗褐飞虱外,还一定程度地较抗
Rice cultivars accounted for more than 90% of the total rice cultivars in Taiwan, but the rice varieties were not resistant to brown planthopper, and Chianung50 was selected as the first japonica rice cultivar against BPH in Taiwan by breeding transgenic rice plants resistant to BPH to japonica rice. The breed was agreed to be popularized by the Taiwan Rice Improvement Commission’s Species Registration Team in June 1981 and is named Tainan 68. Tainan 68 is a pilot project of the Chia-Yi Agricultural Experiment Station in 1973. It was crossed from Nankai-yu114 × [Naukai-yu77 × (Tainan 5 × 2 × ASD7) were selected from the offspring of this breed, except for the inheritance of ASD7 resistance and the resistance to brown planthopper in the late growth stage,
