安丰A是通过分子标记辅助选择技术将广谱抗瘟基因Pi-1和Pi-2导入荣丰B,再与荣丰A测交和连续回交转育而成的三系不育系,2011年6月通过广东省种子管理总站组织的技术鉴定。安丰A表现株型适中,不育性稳定,配合力强,高抗稻瘟病,柱头外露率高,异交结实率高,对“九二○”较敏感,易于繁殖制种。利用该不育系已经组配出安丰优5618、安丰优3301、安丰优3618、安丰优3698和安丰优806等多个杂交稻组合先后于2013年和2014年通过广东省品种审定。
Anfeng A is a molecular marker-assisted selection technology will be broad-spectrum anti-blast gene Pi-1 and Pi-2 into Wing Fung B, and then measured with the Wing Fung A and continuous backcross breeding of three-line sterile lines, In June 2011, it passed the technical appraisal organized by Guangdong Seed Management Station. Anfeng A showed moderate plant type, stable sterility, strong combination ability, high resistance to blast, high stigma exsertion rate, high outcrossing rate, more sensitive to “920” and easy breeding. A number of hybrid rice combinations, such as Anfengyou 5618, Anfengyou 3301, Anfengyou 3618, Anfengyou 3698 and Anfengyou 806, have been used in this CMS line. In 2013 and 2014, Validation.
