SUMMARY OF THE INVENTION An object of the present invention is to provide a highly fertile, inbred inbred line capable of producing economical seed which, due to its excellent overall combining ability, is widely applicable.

High yield maize inbred lines are widely known. Such as line HMv 5302, whose stem is of medium height, vegetative, its leaves are very erect, twisted, their tips are pointed, the color of juvenile leaves is light green, yellowish green, poisonous in adulthood, the crests are many lateral, strongly dense, the anther stamens, cob anthocyanin, tube large, conical, eyes very large, floury, soft, buttocks shallow, crown color typically lemon yellow.

(HMv line 5302 was patented in Hungary in 1992.)

The common disadvantage of these maize lines and other known inbred lines is that their fertility is not high enough, their grain type is unfavorable for seed production, or it is too late for use in Hungarian seed production.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inbred line of mid-ripening vegetative maize which combines well, is widely used, resistant to major plant diseases, and is very economically applicable to the hybrid maize industry because of its fertility and grain type.

BACKGROUND OF THE INVENTION The present invention relates to an inbred line of mid-ripening, vegetative-type maize of the variety HMv 5409, whose leaves are erect, broad, the surface is smooth, the color of the plant is typically greyish, poisonous, stalks, anthocyaninic, its anthocyanin, very long and thick tubes, cylindrical, slightly tapered at the end, very large eyes, very long, with a distinctive feature of the longest widely used lines, dent, slightly soft tissue structure, but not fragile, my callus is shallow, my eyes are slightly opaque ocher, my callus is whitish-yellow.

33. Tube: anthocyanin coloration of the cob

The claimed inbred line provides FAO 300-500 ripening hybrids, which are very productive and have good environmental stability.

The advantage of the line is that it is highly productive and suitable for seed processing, therefore its use as a mother's parent is justified. It has a very good pollen production ability, so it can be used as a father.

A further advantage of the line is that, due to its genetic background and its excellent overall combinability, it can be widely used to produce hybrids.
