Narrative
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.

Pedigree
Description:
Developed by 7 generations of self-pollination from a maize population GT-MAS:gk (PI 561859). This population was derived from a visibly segregating commercial hybrid ear (a Pioneer hybrid) for infection by Aspergillus flavus and selected for resistance to the fungal infection and reduced aflatoxin contamination, which was released as a source of resistance to aflatoxin accumulation.

PRODUCTIONHeterotic GroupThe heterotic group an accession belongs to for breeding purposes. When forming hybrids that demonstrate heterosis (high performance), accessions from different heterotic groups should be crossed.NS - (NS) Belongs to the non-stiff stalk combining group. Accessions belonging to this group produce higher performing hybrids when combined with stiff stalk accessions. Mo17 would be an example of a non-stiff stalk inbred line. MAIZE.DONOR.ACC.NARRATIVE Not Available
