Registration of Nine High-Yielding Tropical by Temperate Maize Germplasm Lines Adapted for the Southern USA

Replicated breeding trials coordinated by North Carolina State University as part of the GEM project, and conducted by several public and private GEM cooperators, have identified nine superior F^sub 2^S^sub 2^ germplasm lines (S^sub 2^ lines derived from an F^sub 2^ population) containing 50% tropic...

Description
Summary:	Replicated breeding trials coordinated by North Carolina State University as part of the GEM project, and conducted by several public and private GEM cooperators, have identified nine superior F^sub 2^S^sub 2^ germplasm lines (S^sub 2^ lines derived from an F^sub 2^ population) containing 50% tropical germplasm by pedigree. All procedures were performed using ear-to-row methods (i.e., each row was planted with seeds from a single ear), except that F^sub 2^ seeds planted at Homestead were bulked by pedigree (i.e., all the F^sub 2^ seed from each tropical source × U.S. inbred were bulked).
