Enhancing Maize Germplasm: Innovations in Protein, Oil, and Starch Content Over Two Years

This report delves into the enhancement of maize germplasm, highlighting significant improvements in protein (up to 13.9%), oil (5.2%), and starch (71.6%). The focus over two years includes germplasm from various races such as Criollo and Tuxpeño, demonstrating notable resistances to NLB, SLB, and GLS. This study presents the performance of top crosses and incorporates collaborative efforts with universities to develop improved lines for various traits, including disease resistance, drought tolerance, and enhanced nutritional profiles.
