Abstract：Zhengpinmai No.8 was bred by Isotope Institute Co.,Ltd.,Henan Academy of Sciences and Henan Jingyuan Seeds Co.,Ltd.,through radiation induced mutation and traditional hybrid technology.Zhengpinmai No.8 was certificated with good quality,high-yield,stable yield and good resistance.The variety was made by F1(parental combination Aikang 58/Zhoumai 18) seed mutagenesis and system selection,and released by the National Committee for Examination and Approval of Crop Varieties in 2016.In 2012-2014,the average yield of Huang-Huai winter group southern winter wheat region regional tests was 7 994.3 kg/ha,4.05% higher than that of CK(Zhoumai 18).The average yield of production test reached 8 370.0 kg/ha,which increased by 5.71% compared with CK(Zhoumai 18) in 2014-2015.The results of quality analysis for two years were protein contents of 15.13% and 14.32%,wet gluten contents of 32.0% and 30.2%,sedimentation value of 37.2 mL and 28.1 mL,stable time of 8.0 min and 7.9 min,the main quality indicators had reached the national secondary standard of strong gluten wheat.Disease resistance identification results showed that the variety was nearly immune to stripe rust,but highly susceptible to leaf rust,powdery mildew,scab and sheath blight.The breeding success of Zhengpinmai No.8 showed organic combination of traditional hybrid technology and radiation induced mutation method was an effective way to speed up the breeding of new wheat varieties.
