N2  - Iowa Stiff Stalk Synthetic (BSSS) and Iowa Com Borer Synthetic No.1 (BSCB1) were established at Iowa State University in the 1930s and 1940s. In 1949, G.F. Sprague initiated a redprocal recurrent selection (RRS) program with these two populations, a process that still continues today. Each population has undergone l5 cycles of RRS, with selection focusing on increased grain yield, reduced moisture at harvest, and reduced root and stalk lodging. This selection program has contributed to the establishment of new breeding populations and has been very successful in releasing public inbred lines. We highlight here some of the accomplishments and contributions of the original BSSS and BSCB1 populations over the past 50 years
