优质早籼稻新品种佳辐占的选育及应用

Breeding and Applicantion of Jiafuzhan——A New Breed of Early Indica Rice of High Quality

经过20多年的研究，采用自创的优质早籼稻新品种选育新途径，选育出大粒（千粒重30g）优质、高产、稳产、抗病虫、适应性广的早籼稻新品种佳辐占．其品质基本上达到了部颁一级优质食用米标准，千粒重、长宽比、垩白度都是当前国内优质早籼稻品种中最好的品种之一．产量水平400-450kg／667m^2，高产的超过500kg／667m^2．广西、江西、广东等省、区已引种成功．2003～2004年在福建省推广11.4×10^4hm^2，为农民增收2亿多元．该品种的育成，解决了水稻育种中长期存在的大粒不优质，早籼稻难优质．优质不高产，优质不抗病等难题．

After 20 years＇ dedicated research under new technologies in breeding high-quality new-breed early indica Rice,Jiafuzhan has been successfully breeding. Its quality has almost reached A-level Editable Rice of Agriculture Department of China, and its average production reaches 400-450 kg/667m^2. with high yield production of 500 kg/667m^2. This new breed 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 × 10^4 hm^2 in Fujian Province and has been introduced and promoted in other provinces like Jiangxi, Guangdong and Guangxi. The successes of breeding Jiafuzhan is a solution to long existed problems in rice industry, such as low quality of big, grain rice and early indica rice,low productivity and poor blast resistance of high quality rice.
