PYRAMIDING CORN RESISTANCE TO ASPERGILLUS FLAVUS, AFLATOXIN CONTAMINATION, AND EAR-FEEDING INSECTS THROUGH SELECTION, BREEDING AND BIOTECHNOLOGY

Objective

(1) Continue evaluation and selection of inbred lines with tropical and sub-tropical germplasm for pyramiding and improvement of resistance and drought tolerance. (2) Field evaluation of the nearly finished inbred lines such as Syn AM1(P43) and TUN61 for hybrid development and in preparation for release; hybrids have been made in 2018 for 2019 test. (3) Characterize Aspergillus flavus isolates, aflatoxin production, and ROS and their possible role in defense signaling in maize-Aspergillus flavus interactions by conducting genome sequencing analysis and corn transformation of overexpression of antioxidant genes.
