Description

OBJECT OF THE INVENTION: A parent line for the production of grain and silage maize hybrids for the production of late-flowering, ripening and water-release hybrids.

Inbred lines suitable for the production of grain and silage maize are widely known. Such as line HMv 5302, of medium maturity, medium stem, vegetative, with erect leaves, especially juvenile leaves strongly erect, twisted, pointed at the end, initially ashy or yellowish green, later poisonous green, coat of arms many lateral, strongly occipital, stubble, cob anthocyanin, large eyes, shallow trace, characteristic crown of lemon.

The drainage of this line of corn and other known lines is not fast enough and their hybrids do not reach the desired level of fertility.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a late flowering, fast-draining maize line which has excellent overall combinability, is widely used for hybrids, and has a high potential for fertility.

BACKGROUND OF THE INVENTION Field of the Invention: A very tall, late maturing corn line having a characteristic silky dark green stalk, leaves densely covered with hairs, highly erect, the head-coat highly dense, with little lateral branch, thick stalk, typically 4 stigmas develops mostly 4 well-developed tubes which are very conical, the eyes are dark-yellow in color, the type is horse-toothed with a deep croup, slightly anthocyaninous, the anthers are weakly anthocyaninic, the color of the stigma is slightly anthocyaninous, its height is very high, its peduncle is long and its leaves often develop on the leaves.

The properties of the maize line of the present invention will be described in more detail below:

The filed line can be used to breed FAO 300-600 rapid-release hybrids, which have a very high potential for productivity and are resistant to major plant diseases.

The advantage of the line is that its hybrids are not only grains, but also have a very high stalk mass and can therefore be used for the production of grain and silage maize hybrids.

A further advantage of the line is that it is not only abundant pollen-producing but also has an extremely high grain yield, so it can be used as a maternal and paternal partner.
