BACKGROUND OF THE INVENTION The present invention relates to an inbred line for the production of early-ripening grain maize hybrids which has excellent general and specific combining ability, tolerates a variety of stresses, especially as a paternal line, has a high pollen production capacity and is well suited for seed production.

A wide variety of inbred lines for the production of early maturing corn hybrids is known. For example: inbred line in SH 298 isolation, generative, good germination, moderate growth, erect leaves, weak leaf pigmentation, non-pigmented feathers, finnish type finnish color, cob color.

The common disadvantage of this inbred line and similar lines is that they have good pollen production ability, but their cimer germination is not late enough, and the stress effects are difficult to tolerate and are therefore limited to the production of grain maize hybrids.

Origin of the line and method of breeding: The line is a 10041 C owned by Cargill.

Breeding method: Isolation, inbreeding

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inbred maize line suitable for the production of early grain hybrids which has excellent combinability, outstanding pollen production capacity, stress tolerance and adaptability, and is particularly suitable for domestic seed production.

BACKGROUND OF THE INVENTION The present invention relates to an inbred line for the production of early-maturing hybrids that have a low growth, the leaves are slightly drooping, the tibiae of the tassel are slightly pigmented, the anthocyanin coloration of the stigma is very low, the anthocyanin The eyes are yellow in color.

The main features of the maize inbred line of the invention are described in more detail below:

- germination, emergence in cold soil: fast

- early spring development: rapid

- leaves: slightly sloping

- onset of anthrax: early

- Coat of arms of the coat of arms: slightly anthocyaninous

- part of the coat of arms of the coat of arms: not anthocyaninous

- anthocyanin color of the ports: slightly anthocyaninous

- date of appearance of stigmas: early

- anthocyanin coloration of stigma: very weak

- anthocyanin coloration of the foliage: absent

- Coat of arms: Slightly sloping

- number of primary side branches of the tassel: few

- density of the main coat of arms: dense

- anthocyanin coloration of stalk internodium: absent

- anthocyanin coloration of stalk nodules: absent

- anthocyanin coloration of secondary roots: absent

- height of plant (without tassel): low

- tube height on stem: low

- length of the peduncle: long

- tube length: short

- center diameter of pipe: medium

- tube shape: slightly conical

- number of tube rows: medium

- the eyeglass type: fiint

- crown color: yellow

- color of cob: anthocyanin

- cob diameter: very thin

- ball angle resistance: excellent

- rooting resistance: good

- fiber angle resistance: excellent

- resistance to corn borer: good

The inbred line in the insulation of the invention can be well condensed.

The line of the present invention has the advantage of having excellent combining ability, very good pollen delivery ability, and adaptive and stress-tolerant capacity for safe and economical seed production.
