Narrative
In field evaluation for aflatoxin contamination in 2004 and 2005, GT602 had 32 ng g-1 and 51 ng g-1 respectively, while resistant control Tex6 had 69 ng g-1 and 120 ng g-1. In 2005 hybrid test, GT601 x Cy1 and GT602 x Cy1 had 113 ng g-1 and 105 ng g-1 aflatoxin, whereas the commercial hybrid controls had up to 266 ng g-1 aflatoxin. Adapted to southeastern U.S. region. GT601 flowers about one week earlier than GT602, with about 60 d to 70 d from planting to flowering depending on the planting date. GT602 has colorless pericarp, red cob, and browning silk, P-wrb.

Pedigree
Description:
Developed by seven generations of self-pollination from a maize population GT-MAS:gk (PI561859) (McMillian et al., 1993). This maize population was derived and selected from a visibly segregating hybrid ear that was infected by Aspergillus flavus (Widstrom et al., 1987) for reduced aflatoxin contamination. McMillian et al. (1993) released this maize population GT-MAS:gk as a source of resistance to aflatoxin accumulation.
