GT888 was derived from GEM population DK 888:N11, and 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 ex Fr.). It was compared to three inbreds including Mp 313E, Mp 717, and Mp 719, which are known standards that resist aflatoxin contamination. This inbred also exhibits heterosis when crossed to stiff stalk testers B 17, B 73 and LH 132, and was assigned to the non-stiff stalk group. GT888 tasseled and silked approximately five to eight days later than a cohort of non-stiff stalk standards. | 1917198 | PI 670116 |

| 2 | PI 662046 | Mp719 | Zea mays L. subsp. mays | Mississippi, United States | NC7 | | | 2011 | DEVELOPED | | | | | | Breeding material | Mp719 was developed from Mp715 X Va35 by self pollinating for eight generations and selecting for reduced levels of aflatoxin accumulation in the grain. In a series of replicated field experiments conducted in Mississippi from 2004 through 2010, immature ears were inoculated with an Aspergillus flavus spore suspension, and aflatoxin levels in the grain were determined after harvest. Mp719 exhibited a level of resistance to aflatoxin accumulation that did not differ significantly from that of Mp715, which is resistant to aflatoxin accumulation, but was significantly less than that of Va35, which is susceptible to aflatoxin accumulation. In these experiments, Mp719 flowered 13 days earlier than Mp715. Plant heights for Mp719 was approximately 1.7 m compared to 2.0 m for Mp715 and 1.3 m for Va35. Mp719 has yellow kernels and red cobs. | 1880817 | PI 662046 |
| 3 | PI 659665 | GT603 | Zea mays L. subsp. mays | Georgia, United States | NC7 |  | | 2010 | DEVELOPED | | | | | | Breeding material | Initially selected from early self-pollinated lines under the experimental name GT-P50 with resistance to A. flavus colonization in the laboratory bioassay and reduction in aflatoxin contamination in the field studies from 2004 to 2007. Had aflatoxin levels similar to or lower than the released sister lines GT601 (PI 644026) and GT602 (PI 644027) and the controls Mp313E (PI 539859) and Mp715 (PI 614819) but the maturity was earlier than Mp313E and Mp715. In hybrid performance tests in 2005 and 2009, GT603 exhibited better combining ability with Stiff Stalk Synthetic (SSS) inbred (B73) than a non-Stiff Stalk Synthetic inbred (Mo17) for both aflatoxin levels and yields. | 1843973 | PI 659665 |

Plant 226 cm in height to tassel tip, 79 cm to base of top ear, top ear internode is 13 cm long, no tillers, single ear per stalk, and normal cytoplasm. Leaf color 5GY 4/4 (Munsell Color Charts for Plant Tissues), less than 30 degree angle from stalk, light sheath pubescence, no marginal waves, few longitudinal creases, 8 cm at widest point of ear node leaf, 85 cm ear node leaf, with 12 leaves per mature plant. Tassel has 9 lateral branches, 30-40 degree branch angle from central spike, penduncle length from top leaf to basal branches 11 cm, medium pollen shed, anther purple and glume green with purple stripe. Ear 13 cm long, 40 mm mid-point diameter, 74 grams, 16 distinct and straight kernel rows, green silk, husk light green when fresh and buff when dry, husk extension 8-10 cm beyond ear tip, husk leaf less than 8 cm, shank 8 cm long with 7 internodes, pendent at dry husk stage, slight taper, and average drying time (unhusked ear). Kernel 12 mm long, 8 mm wide, 4 mm thick, 30-60% rounds, colorless pericarp, aleurone homozygous and white, endosperm yellow, normal starch type endosperm, and 28 grams per 100 seeds. Cob 30 mm diameter at mid-point, strong, and red. Disease and insect resistance not tested. Most closely resembles LH119 for maturity, plant type, ear type, kernel type, and usage. In later progeny inbred releases, the developer writes: LH132 has been used as a replacement for B73 in many hybrid combinations. LH132 is a superior seed parent to B73 and greatly improved the production and quality of hybrid seed. LH132 also contributes a larger seed size which reduced the amount of discard that was common with B73. LH132 hybrids have lower ear placement than comparable B73 hybrids and have significantly improved stalk and root qualities. | 1157405 | PI 601004 |
