Abstract: The study aims to satisfy peanut production demand, and breed peanut varieties with high yield and resistance to bacterial wilt by using cross breeding method in Quanzhou Agricultural Science Research Institute. A new peanut variety‘Quanhua 27’was bred with female parent‘626- 2- 1’and male parent ‘Quanhua 327’. In 2010- 2011, the average pod yield of‘Quanhua 27’was 5173.95 kg/hm2 in peanut regional test in Jiangxi, increased by 10.10% compared with the control variety‘Shanyou 523’; the average seed yield was 3588.75 kg/hm2, increased by 7.64% compared with the control. At the same, in Guangxi peanut regional test, the average pod yield was 4082.4 kg/hm2, increased by 12.17% compared with the control variety ‘Guihua 21’; the average seed yield was 2582.25 kg/hm2, increased by 4.71% compared with the control. In 2014- 2015 peanut regional test in Fujian, the average pod yield was 3901.5 kg/km2, increased by 9.3% compared with the control variety‘Quanghua 7’; the average seed yield was 2779.5 kg/km2, increased by 13.1% compared with the control.‘Quanhua 27’was identified with high resistance to bacterial wilt in experimental field by Oil Crops Research Institute, Chinese Academy of Agricultural Sciences.‘Quanhua 27’ was certified (identified) as a new peanut variety with high production and resistance to bacterial wilt by the Variety Certification Committee of Guangxi and Jiangxi in 2012, and suitable for planting in Guangxi, Jiangxi and Fujian.
