Breeding and application of Jiafuzhan, a new elite early indica rice cultivar in China

After 20 years of dedicated research, Jiafuzhan has been successfully developed under the new technologies in breeding high-quality early indica rice cultivars. Its rice quality has almost reached the A-level Editable Rice of Agriculture Department of China, and its average production reaches 400–500 kg/(666.7 m2). This new cultivar also has other characteristics such as enhanced resistance of blast and fallen, steady productivity, and strong adaptability. Jiafuzhan has been put into production of over 11.4 × 104 hm2 in Fujian Province and has been introduced and extended in other Provinces like Jiangxi, Guangdong, and Guangxi, China. The successes of breeding Jiafuzhan is a solution to the existing perennial problems in the rice industry, such as poor grain quality of big-grain rice and early indica rice, low productivity, and poor blast resistance of elite rice.
