FIELD OF THE INVENTION The present invention relates to an excellent cold tolerance and good adaptability late-ripening maize line (Zea mays L.) of the type GK 43 which can be advantageously used for the production of hybrid varieties.

GK 43 is an inbred corn line that is well-known for the domestic conditions, including the characteristics of the best known genotypes, and developed from mid-high and dent-eye.

The hybrid variety can be used both as a father and as a mother. Its use as a father is promoted by its excellent pollen capacity and its use as a mother with a strong stem and favorable tube type. These properties have been validated by hybrid MTC 318 and Sze TC 338.

The object of the present invention is to create a late maturing, excellent cold tolerant corn line that is well adapted to domestic conditions and can be used as both a father and a mother.

The present invention, the GK 43 maize line, has the following characteristics: the first leaf sleeve has a medium anthocyanin color, the first leaf has a blunt tip, the angle between the crankshaft and the flanks on the coat of arms varies from medium to high, the height of the plant along with the coat of arms is low to medium, tube thickness and number of eye lines (12-14 pieces) medium, tooth-toothed and caudal to moderately anthocyanic.

The morphological description of the invention is described in UPOV Ta / 2/4/1980. Based on these guidelines, we will give you the following details:

(1) - anthocyanin color of the first leaf sleeve - medium (2) - first leaf leaf length - medium (3) - first leaf leaf width - medium (4) - first leaf leaf width ratio - medium (5) - first leaf top shape - blunt (6) - leaf position above tube - intermediate position (7) - coat-of-arms appearance - late (8) - start of bloom coat - late (9) - coat on anthocyanin coloration - no (10) - on time of bibe appearance - late (11) - anthocyanic coloration of the bibe - no (12) - anthocyanin coloring of the coat of arms on the coat of arms - no (13) - anthocyanin ring on the coat of arms on the basis of the coat of arms - missing (14) - anthocyanin anthocyanin - no (15) - anthocyanoid stalks coloring at 5-7 intemodium - no (16) - anthocyanin coloration of the leaf sleeve at the 5-7 interode - no (17) - flattened at the edge of the leaf sleeve ge - medium (18) - crest angle between the main axis and lateral branches - medium to large

The maize line GK 43 prefers a more humid, warmer climate. The disease resistance of the tubes is excellent, which is especially true in cool and rainy years. It also inherits this advantageous feature in hybrids. The hard endosperm of the eye also appears in the hybrids produced with it, which makes it suitable for industrial use as well. Excellent cold hold line. Even in a cool, rainy spring, it is steadily rising, there is no shortage in the stock, which reduces the risk of hybrid production.

The good adaptability of the GK 43 line is also evidenced by its long-lasting ability to deliver pollen, but it is also able to wait for pollen for a long time because it does not dry quickly. All of this allows the line to be used from FAO 200 to FAO 500.
