【Abstract】 Dajingjiu 26 was a silage maize hybrid with high yield, wide adaptability and high quality. This maize variety had been bred by Henan Province Dajingjiu Seed Industry Co., Ltd., using 9889 inbred line as female parent and 2193 inbred line as male parent.In the 2014-2015 national silage maize hybrid regional test(Beifangchun maize group), the average biological yield(dry quality)was26 277.0 kg/hm2. In the 2016 national silage maize variety production test, the average biological yield(dry quality)was 28 845.0 kg/hm2.In the 2014—2015 regional trial of silage maize hybrids in Ningxia, the average grain yield was 11 356.5 kg/hm2, and the biological fresh quality was 103 911.0 kg/hm2, increasing by 12.5% and 16.5%, respectively, compared with the control seeds. The hybrid has passed the national and provincial examination for 4 times successively, and the examination area is 16 provinces and cities including Xinjiang,Heilongjiang, Jilin, Liaoning, Inner Mongolia, Ningxia, Beijing, Tianjin, Shaanxi, Shanxi, Hebei, Shandong, Henan, Jiangsu, Anhui and Hubei.更多还原
