B37collection, the appearance of the biby-to-medium, the coat of bloom medium, the bibe and the adult leaf pods are weakly with antarctica, with little or no coloring of the corkscrews, the antarctic ring does not form on the c-thorns of the c, and the crest on the coat of arms is heavily curved, the crankshaft on the crest, the crankshaft above the lower part of the crankshaft. hero, tubular and tubular, and the number of eye gangs on the tube is medium, the tube is crooked, ash-headed, the eye-crown is yellow, and the eye is back with a yellowish orange. Characteristically, the leaf above the tube curved slightly, the colouration of the corncrakes is weak to medium intensity, the plant is medium high, the head of the main tube is lightened by the height of the plant, and the tube is conical-cylindrical, with the capillary coloring. ŕ

Description

The present invention relates to a three-line hybrid maize belonging to the TC 277 early maturity group (FAO 300) of Szeged, which can be used as grain maize.

The lineage formula of the Szeged TC 277 hybrid maize lines (Iodent kinship circlexlodent kinship) χ χ B37 kinship line. The inbred lines were bred from the above mentioned kinships. The parent line from the B37 lineage is abundant in pollen.

The initial development of the TC hybrid is accelerated especially after rooting. Stems strong, rarely broken. It has excellent drought resistance. Early flowering prevents drought from mid-July. It has a rapid, cool morning growth and a high dry matter accumulation, and can be harvested early under these conditions.

The tube is conical-cylindrical, thin, of medium length and has a number of lines formed on it.

The purpose of breeding is to create a three-line hybrid with rapid onset development, excellent drought tolerance, and a high level of dry matter accumulation in the eyes due to cool thanks. The hybrid is mature and abundant.

The morphological and phenological description of the hybrid maize TC 277 from Szeged in the UPOV TG 2/4 system is as follows:

anthocyanin coloration of first leaf pod - unobserved leaf position above tube - onset of slightly curved coat of arms on 50% of plants - anthocyanin coloration of medium anthers - time of appearance of weak to medium stigma on 50% of plants - early to medium stigma anthocyanin coloration - anthocyanin coloration of cornea in weak coat of arms - anthocyanin ring of faint to medium coat on base of cornea - lack of anthocyanin coloration of leaf sheath - position of lateral branches on very weak crest - number of primary branches on low crest - small lateral crest crankshaft length above the uppermost branch - average plant height including tassel - average crown height and ratio of plant height - medium tubing length - medium pipe length - medium pipe thickness - thin tube shape ja - number of rows of conical-cylindrical tube - medium eye type in the middle third of the tube - horse-tooth crown color - yellow eye backside color - yellow-orange cob anthocyanin color - has

In OMMI field trials, the Szeged TC 277 hybrid was 8% more productive than the standard Dekalb 250 hybrid and was produced at the Helga level of the other standard Pioneer hybrid.

The advantage of the Szeged TC 277 maize hybrid is that it has crop safety and stability even under extreme weather conditions.
