Application and Innovation of Lancaster Maize Germplasm Resources in Northeast China

After MO17,the representative Lancaster maize germplasm was introduced to northeast China,local materials were used to overcome its late maturity and un-coordinated male and female development,and excellent inbred lines such as Dan 1324,Ji 1037,Ji 846,Ji 842,W9706,412,495,416,485,4F1,419,B414,Si-144,Longkang 11 and Hu 150 were released by using MO17 in maize breeding programs.It soon became a core germplasm material resistant to silk smut in the spring maize area of northeast China.In future breeding programs new Lancaster maize germplasm resources and local germplasm materials could be used to form advantage groups of Chinese characteristics with 78599 as a disease-resistant source.
