BACKGROUND OF THE INVENTION The present invention relates to inbred maize line L 290. The maize line of the invention differs from line L 330 in that the crankshaft cornea has a medium density, the lateral branches are curved to strongly curved, the tube is long, and the intensity of the coloring of the tube is strong.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a highly combinable, high yielding corn line.

The corn line of the invention is characterized in that the angle between the leaf and the stem is very small, the position of the leaf is straight and slightly curved, the flowering time of the male is late, the anthocyanin coloration of the base of the crest is lacking, anthocyanin coloration of the ear canals is absent or very weak, 15 anthocyanin coloration of the anthers is absent or very weak, the crankshaft densities are medium, the angle between the crankshaft and side branches is small to medium, the position of the side branches is curve-strongly curved, number of first branches on the tube, the appearance of the stigma is late to very late, the anthocyanin coloration of the stigma is absent, the anthocyanin coloration of the pod is absent or very weak, the crest of the crest is medium, the cranial axis above the uppermost is medium, with the sea high, the ratio of the height of the main tube to the height of the plant is high, the length of the peduncle is short to medium, the length of the tube is medium, its shape is cylindrical, the number of eyes is small the color of the back of the eye is orange, the cob is anthocyanin colored, the intensity of the cob is anthocyanin. SUMMARY OF THE INVENTION It is an object of the present invention to provide a highly combinable, high yielding corn line.

Figure 1 shows the plant.

The corn line of the invention will be described in detail below.

Letter: angle between leaf leaf and stem very small to small (2) Letter: position of leaf leaf above tube: straight, slightly curved (2) Coat of arms: date of male flowering (50% of plants) late (7) Coat of arms: anthocyanin coloration of the base of the cornea missing v. very weak (1) Coat of arms: anthocyanin coloration of corneas (without foundation) missing v. very weak (1) Coat of arms: anthocyanin coloration of ports (on fresh ports) missing v. very weak (1) Coat of arms: crankshaft gland density medium (5) Coat of arms: angle between crankshaft and side branches Small to Medium (4) Coat of arms: position of the side branches curve-strongly curve (6) Coat of arms: number of prime branches little (3) Tube: time of appearance of bibe late to very late (8) Tube: anthocyanin staining of stigma missing (1) Letter: anthocyanin coloration of the leaf pod missing v. very weak (1) Coat of arms: crankshaft length above the lowest lateral branch medium (5) Coat of arms: is the crankshaft length above the uppermost lateral branch medium (5) Plant: height including the coat of arms high (7) Tube: the relationship of the height of the main pipe to the height of the plant large (7) Tube: length of the pedicle Short to Medium (4) Tube: length long (7) Tube: thickness medium (5) Tube: form cylindrical (3) Tube: number of rows of eyes little (3) Tube: the type of eye in the middle third of the tube intermediate type (3) Tube: color of the crown yellow (3) Tube: color of the back of the eye orange (5) Tube: anthocyanin coloration of the cob present (9) Tube: anthocyanin staining intensity of the cob strong (7)

The advantage of the corn line is its good combinability.
