The objective of this research is to provide information and germplasm that will be used by private seed companies to create corn hybrids that resist accumulation of aflatoxin.
Approach: Demonstrate that commercially acceptable inbreds and hybrids can be created by using molecular markers to incorporate chromosome regions with genes for resistance from two different donor sources of resistance to A. flavus and alfatoxin production; continue to identify molecular markers linked to genes for resistance to Aspergillus ear rot and to aflatoxin production in donor sources Mp313E, Tex6, M182 and Oh516; determine the genetic basis of resistance to aspergillus ear rot and to aflatoxin production for identified sources and aflatoxin-susceptible and aflatoxin-resistant plants, and perform molecular marker analyses of the DNA samples to identify associated chromosome regions.
