A TROPICAL Synthetic (TROPICS) maize population was developed to explore genomic responses to selection for flowering time. The inbred lines used as parents of TROPICS were chosen based on multiple publications (Nelson 2009 Ch. 4 and 5; Nelson et al. 2006; Nelson and Goodman 2008) in which tropical and semi-tropical lines were evaluated for grain yield in testcrosses with U.S.-temperate adapted lines. Among the aforementioned studies, CML10, CML258, CML277, CML341, CML373, Tzi8, and Tzi9 were top candidates as exotic germplasm for U.S. maize improvement; thus, the potential for these lines to contribute unique variation in the context of temperate maize improvement was the basis of selecting them. This population was used in a parallel selection experiment at multiple locations spanning a latitudinal gradient across the United States.References:Nelson, P. T., Jines, M., & Goodman, M. (2006).
