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30 g)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400~450 kg/667 m2,高产的超过500 kg/667 m2.广西、江西、广东等省、区已引种成功.2003~2004年在福建省推广11.4×104hm2,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.农业部转化资金(02EFNZ16900762);; 福建省水稻育种攻关项目;; 福建省重大专项(2004NZ01-3);; 福建省三项费用(2000-Z-029);; 厦门市农业创新(3502Z20032007);; 国家后补助基金(2004年)资
