Abstract: In order to fully understand the characteristics of the super-high yield wheat variety ‘Yannong 999’ and to provide reference for the breeding of super-high yield varieties. We analyzed the breeding objectives, breeding procedure, characteristics and breeding strategies of ‘Yannong 999’. The results showed that: the yield of ‘Yannong 999’ was outstanding, which was 12255.0 kg/hm2 in the high-yield establishment of wheat, created the highest record of wheat yield in Shandong and the highest winter wheat yield record in the national acceptance test by the experts of ministry of agriculture; it had good quality, and reached the national strong gluten wheat standard for two years in the regional test of the national Huang Huai southern winter water group; it also had wide adaptability and had been approved by Shandong and the Nation; the comprehensive resistance in the field was good. The breeding of super-high yield varieties should strengthen germplasm innovation and the application of various breeding methods, pay attention to select the high grain weight of panicle, increase the biological yield, and emphasize the coordination improvement of yield and quality.
