HU219622B - Alberta variety of double line corn-hybrid (zea mays l.) - Google Patents

Abstract

The subject of the invention is single-cross hybrid corn called Alberta, which is created from inbred Pioneer lines, the lower leaves are slightly bent above the tube, the beginning of flowering is early-mid on 50% of the plants, the anthocyanin coloration of the anthers on the crest is weak, the pistil is early-mid appears and is not or very weakly colored with anthocyanin, on the crest the closed anthocyanin ring is absent at the base of the ear-cup, the anthocyanin coloration of the leaf sheath is weak, on the crest the side branches are intermediate, the number of primary branches is few, the length of the main axis is short above the lower side branch, and medium above the upper side branch, the fit of the main tube is of medium height in relation to the height of the plant, the tube peduncle is medium long, the tube is short, thin in diameter, cylindrical, with few rows of eyes, and the back side of the eyes is yellowish-orange. Its characteristic is that the crest is not or only very weakly colored with anthocyanin, the plant together with the crest is medium tall, the eye is horse-tooth type, the eye crown is yellow, and the cob is colored with anthocyanin. ŕ

Description

BACKGROUND OF THE INVENTION The present invention relates to a single crossbred hybrid maize of the Alberta variety which can be used as grain and silage feeds.

The Alberta SC hybrid was created by crossing inbreed corn lines from Pioneer.

The aim of the breeding was to produce a two-line hybrid maize with a heterozygous effect on green weight and grain yield, and a new hybrid with broad ecological adaptability.

Figure 1 shows a plant of the variety of the present invention.

The morphological and phenological description of the Alberta cultivar, single-cross hybrid maize, in the UPOV TG / 2/4 (1980) system is as follows: leaf: leaf position above the tube - slightly curved crest: beginning of flowering on 50% of plants - early- medium coat of arms: anthocyanin coloration of anthers - weak tube: time of appearance of stigma on plants

50% - early to medium tube: anthocyanin coloration of the sternum - missing or very weak coat of arms: anthocyanin coloration of the cornea - missing or very weak coat of arms: closed anthocyanin ring of the cornea

Based on - Missing leaf: the leaf pod anthocyanin coloration - weak coat of arms: position of the side branches - intermediate position coat of arms: number of primary branches - few crest: length of the crankshaft above the lowest lateral branch - short crest: length of the crankshaft above the highest lateral branch - medium

plant: height with coat of arms - medium

tube: fit high- the height of the plant barracks - medium tube: length of the stem - medium tube: length - short tube: diameter - thin tube: shape - cylindrical tube: number of rows of eyes - few tube: the type of eye is the middle of the tube third - horse-tooth tube: color of the crown - yellow tube: the back of the eye color - yellow-orange tube: the cube is anthocyanin coloration - present
