Description

BACKGROUND OF THE INVENTION The present invention relates to a maize inbred line suitable for producing low moisture grain hybrids. Inbred lines suitable for the production of maize hybrids are widely known.

Examples include the HMv 5302 line, which has a medium-high, vegetative growth, leaves with erect leaves, a multi-lateral branch, dense, the ear lobes, anthers, a stomach and a cob are of medium anthocyanin, the eyes are very large, floury, soft, They are transitory, the trunk is shallow and the color of the crown is lemon yellow. 10 (HMv line 5302 was granted definitive patent protection in Hungary in 1992.)

This line of corn and other known early lines are not early enough, their grain filling and drainage under the Hungarian climate does not reach the desirable 15 levels. Breeding times are not stable enough.

Figure 1 shows the variety according to the invention in the herd.

Figure 2 shows a tube of the type of the invention.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fodder corn line suitable for producing low grain moisture hybrids which has stable maturation under Hungarian climatic conditions and requires little artificial energy to dry its hybrids.

BACKGROUND OF THE INVENTION The present invention relates to a late-maturing, high-growth, generative-type maize inbred line having a very small angle between the leaves and the stalk, a slightly curved leaf position, a tassel, cornea, anthers, stems, anthocyanins. lacking or very poor coloring, long tube, thick, conical-cylindrical in shape, horse-toothed, hard dent, reddish-orange in color.

The characteristics of the inbred line of the present invention will be described in more detail below.

HU 225 282 Β1

The filed line is intended to produce FAO 200-500 hybrids with high density, rapid grain settling and drainage, which mature safely even in a cool, rainy climate and are resistant to prevalent diseases. 5

The advantage of the line is that its genetic background is different from most known lines, and its excellent combinability makes it widely used.

A further advantage of the line is that it is a generous pollen producer, has a very good seed yield, excellent seed grading, and therefore can be advantageously used as a maternal and paternal partner.

Another advantage of the line is that it delivers the ability to rapidly dehydrate dominantly into its hybrids, so it can be advantageously combined with weaker dehydrating partner lines.

Claims (1)

Patent Claim Point 15 inbred lines for the production of fodder maize hybrids with a low grain moisture content of the variety HMv 5325, which are high-growth, slightly crooked, have long tubing, thick, coccyx anthocyanin, grain type horseshoe, capillary, anemone, anthocyanin coloration is absent or very weak, the time of male flowering and stigma appearing late, the crown of the crankshaft is medium to dense, and the eyes are typically reddish orange.
