Narrative
GT-P43 and GT-T61 are yellow dent maize (Zea mays L.) line developed and released jointly by the USDA-ARS Crop Genetics and Breeding Research Unit and the University of Georgia Tifton Campus in 2024. GT-P43 and GT-T61 were developed by six generations of self-pollination from two different synthetic populations. GT-P43 was derived from a synthetic population of US and CIMMYT hybrids and has resistance to corn earworm, tassel and silk date of about 63 days, 10 days early than the control MP313E. GT-P43 fits in Non-Stiff Stalk (NSS) group. GT-T61 was selected from a synthetic population developed by Dr. Neil Widstrom, originally from China. GT-T61 has lower both aflatoxin and fumonisin and fits in Stiff Stalk (SS) group. GT603 was initially selected from early self-pollinated lines with resistance to Aspergillus flavus colonization in the laboratory bioassay and reduction in aflatoxin contamination in the field studies from 2017 to 2022. Both had aflatoxin levels similar to or lower than the control Mp313E (PI539859) but the maturity was about 10 days earlier. GT-P43 has colorless pericarp and red cob but GT-T61 has colorless pericarp and white cob.

Description:
GT-P43 and GT-T61 were developed by six generation of self-pollination from two different synthetic populations, which were open pollinated with more than 20 different hybrids from CIMMYT, US and China with hard-flint type maize
