Breeding material
N103 flowers about 3 days later than BI4A, and has very upright leaves and a very rigid stalk with highcrushing strength resistance. It yields well as a line but tends to tiller. It has more than average kernel rows (16-18) and good husk cover. It has excellent downy mildew, rust and aphid resistance, and is better than average in resistance to eyespot, maize dwarf mosaic virus, diplodia stalk rot, first brood corn borer and root regeneration after western corn rootworm damage. Maturity classification is about AES800.
