Registration of Maize Inbred Line GT888

Maize (Zea mays L.) inbred line GT888 (PL‐364, PI 670116) was developed and released by the USDA‐ARS in cooperation with the University of Georgia and in participation with the USDA Germplasm Enhancement of Maize (GEM) project. GT888 was derived from GEM population DK888:N11 (GEMN‐0177), which has 50% tropical and 50% temperate parentage. GT888 is a yellow dent inbred that was selected through a pedigree breeding program for improved resistance to aflatoxin contamination produced by the causal organism Aspergillus flavus (Link: Fr.). It was compared with three inbreds, Mp313E, Mp717, and Mp719, which are known standards that resist aflatoxin contamination. GT888 also exhibits heterosis when crossed to stiff stalk testers B14, B73, and LH132 and was assigned to the non‐stiff stalk group. GT888 tasseled and silked approximately 5 to 8 d later than a cohort of non‐stiff stalk standards.
