Plants are dark green in color and very drought resistant. Grain is light yellow in color and cobs are white. It contributes to hybrids high yield, drought resistance, resistance to ear dropping, a low shelling percentage and in some combinations weak roots. It is usually used as a seed parent in single cross production. It was used in K1639. It is not closely related to other inbreds.1645588PI 693369

This inbred is important because it was among the first maize inbred lines that would generate embryos from callus tissue culture. This trait made it important in early maize genetic engineering.

23PI 607512N7AZea mays L. subsp. mays Nebraska, United StatesNC7KERNELS1992DEVELOPED1968Breeding materialYellow 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 AES700.1082775PI 607512

Reaches 50% silk emergence 13 days earlier, is 36 cm shorter in plant height, and is 28 cm shorter in ear height than A632 when grown near St. Paul. In single and three-way-cross hybrids tested in central and northern Minnesota over 3 years, A662 demonstrated high GCA for grain and yield and satisfactory GCA for stalk strength.
