Introgression of Tropical Germplasm to Reduce the Damage of Ear-Feeding Pests and Develop Products for Organic Corn Production.

Wenwei Xu, Gary Odvody, W. Paul Williams, Patrick Porter, and Greg Cronholm.

Drought, corn earworm, and mycotoxins (aflatoxin and fumonisins) cause significant yield reduction and economic loss to corn producers. The corn-breeding program at the TAES-Lubbock Center has been developing drought tolerant and corn earworm (CEW)-resistant germplasm (lines and hybrids) by introgressing tropical germplasm. Our non-transgenic experimental hybrids had significantly lower CEW damage under heavy natural infestation, lower aflatoxin and similar yield when compared to commercial hybrids. These multiple-stress tolerant hybrids are non-transgenic, have yellow or white kernels. They have a great potential for organic corn production.
