Description

BACKGROUND OF THE INVENTION The present invention relates to an inbred maize line for the production of early cold-tolerant grain maize hybrids of the variety HMv 5219. Inbred maize lines suitable for the production of early grain hybrids are widely known. Examples include the inbred line HMv 5209, which is a high-growth, dark green, erect leaf, has few coats of arms;

This line of maize, as well as other lines of maize, is either not early enough or not sufficiently cold tolerant to produce short grain maize hybrids. Because of these deficiencies, breeding times are often delayed and can be harvested at high humidity.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inbred line of early flowering and maturing hybrids that exhibit good cold tolerance and rapid water release in hybrids, which produces even balances under cool, wet conditions, and is quick and balanced for grain maize utilization.

BACKGROUND OF THE INVENTION The present invention is an early-flowering, medium-height, generative-type inbred corn line having broad leaves in the intermediate position, having a median multi-lateral, slightly curved, strongly dense, anthocyaninic, tubular, caudal, caudal yellow in color, columnar in shape, horse-type with a large oval cap.

Figure 1 illustrates a tube of the type of the invention. The main features of the subject line of the invention are described in more detail below:

The filed line allows the production of early cold-tolerant grain corn hybrids. The main advantage of the line is that it contributes significantly to both cold tolerance and rapid water release of hybrids.

A further advantage of the line is that it has a very high pollen production capacity, a high seed quality and a very good quality, and can therefore be used advantageously as a maternal and paternal partner.
