0PI 540462ARK. SWCB SYN.Zea mays L. subsp. mays Arkansas, United StatesNC7KERNELS1990DEVELOPEDBreeding materialOriginal population developed for a source of genes for resistance to the southwestern corn borer. Selection was for resistance to leaf-feeding damage and to stalk invasion. Resistance to corn virus complex (maize dwarf mosaic A and maize chlorotic dwarf) disease. It is predominately a yellow endosperm synthetic with maturity classification of AES1000.1435398PI 540462

SYN.Zea mays L. subsp. mays Arkansas, United StatesNC7KERNELS1990DEVELOPEDBreeding materialSynthetic developed as a source of genes for resistance to leaf-feeding damage by the southwestern and European corn borers. Selection for resistance was conducted using manually infested southwestern corn borer eggs. Yellow-endosperm synthetic with a maturity classification of AES8001435399PI 540463
