Narrative

Yellow dent inbred line selected from Oh7 x 'Stiff Stalk Synthetic' gamete. It flowers about 1 day later than B14A. It has good general combining ability and is very high yielding in certain crosses. N7A machine-combines poorly at high moisture levels but is a very good sheller at lower moisture levels. It has good late season health as a line but tends toward premature death in crosses. It tends to have above average resistance to leaf freckles and wilt and has good resistance to wheat streak mosaic virus and downy mildew. Its cold germination and early vigor should be adequate for use as a single cross seed parent, and pollen shed is adequate for its use as a male. Tassels extrude well for detasseling but pull hard. Maturity clasification is about AES700.
