FIELD OF THE INVENTION The present invention relates to a cold-tolerant early-ripening, three-line hybrid maize of the variety Sat TC 259, which can be produced as both grain and silage maize.

The maternal single-crossing lines for the production of the Se TC 259 three-line hybrid are within the B 37 and A 654 lineages, the paternal line being international. A hybrid of maternal basic-single crossing with an international father resulted in an early-seeded, cold-tolerant, fast-growing, FAO 200 breeding hybrid.

The Sz Sz TC 259 variety is similar to the Szeged TC 247 hybrid, with anthers yellow, the coat of arms of medium size and the coat of arms 35-36 cm.

Sat TC 259 has a multicolored anthers, slightly anthocyanin, medium / large, 38-41 cm long.

Its special cultivation value is that the new hybrid is fast-growing, short-growing and spring-cold tolerant. Its cold tolerance makes it suitable for early sowing and also for cultivation in the cooler climates of countries to the north of Hungary.

The object of the present invention is to provide a three-line hybrid maize in the FAO-200 ripening group which is a high-yielding, spring-tolerant, early-sown, fast-growing crop for both grain and silage.

The subject matter of the present invention, whose maternal single crossing lines belong to the relatives B 37 and A 654, the paternal lineage is described by the UPOV TG / 2/4 method as an international line:

the anthocyanin coloration of the first leaf pod is medium

length of first leaf disc medium first leaf plate width first leaf plate length / medium width ratio medium apex of first leaf from dull to round leaf position above the tube intermediate full-time time of appearance of coat of arms very early coat of arms bloom beginning anthocyanin anthers very early coloration none or very weak time of appearance of bibe early anthocyanin coloration of the stigma on the coat of arms is anthocyaninous weak coloration the anthocyanic ring on the coat of arms is the corn strong cap under va miss anthocyanin of the node medium anthocyanin coloration of stalk fragments leaf anthocyanin medium coloration weak hairline edge of leaf sheath on crest of crankshaft and side branches medium angle medium on the crest the position of the side branches on the crest is the primary branch slightly curved number missing or very little

the lowest branch on the crest crankshaft length crest the longest crankshaft medium over the side branch very long size of coat of arms medium / large, 38-41 cm long plant height main tube origin and plant height medium The proportion medium length of the pedicle long tube length medium tube thickness thin tube shape conical-cylindrical number of rows of eyes few eye type dent crown color yellow color of the back of the eye yellow anthocyanin coloring anthocyanin has intensity of coloration medium red.

The comparative variety of FAO ripening group 200 is Mona. Sat TC 259 and Mona hybrids have the same productivity. Sat TC 259 has a 1% higher moisture content at fracture than Mona.

Mona's plant population has a slight stalks of 0.71.4%.

The hybrid is suitable for growing both grain and gluten maize. The eye is semi-toothed, favorable for silage production. The eyes are juicy for a long time, and water is advantageous for silos.

Produced as grain corn, it can be harvested early due to its short growing season. When harvesting, low grain moisture content reduces the drying cost.

An advantage of the present invention is that it is spring-hardy, fast-growing, early-maturing, highly productive for grain and silage production.
