Its flowering time in effective heat unit is 676 'C, its anthocyanin coloration is absent or very weak on its stigma, there is no closed anthocyanin ring on the base of the coat of arms of the coat of arms, or anthocyanin coloration of the leaf sleeve in the middle of the plant is missing or very pale. Eye type is horseshoe, crown orange color. The anthocyanin coloration is absent on the Csutka's capercaillie. Ί- AbfCL -1-

Description

BACKGROUND OF THE INVENTION The present invention is based on simple hybrids of early to mid-ripening, inbred two unnamed original PIONEER lines, bred in seven self-fertilizing and selection cycles for horse-tooth grain.

The subject variety is a variant of the U.S. 354 maize variety, most closely resembling the fact that the 354 has a tuft of 60-70, the female blooms 70-90 and the tube is located higher on the stem and opposite to the stem and root less resistant.

SUMMARY OF THE INVENTION An object of the present invention is to provide early to mid-ripening maize varieties with good stalk strength, good crop yield, and broad-leaved FAO 300 variety.

According to the intended purpose, FAO 220 early-middle-ripening grain maize produced in the first third of the FAO 300 ripening group

- female flowering time in effective heat unit 676'C,

- stigma missing or very weak in stigma,

- there is no closed anthocyanin ring at the base of the crest of the coat of arms,

- the anthocyanin coloring of the pod is absent or very pale in the center of the plant,

- type of eye: horse-tooth,

- its crown is orange-yellow and

- there is no anthocyanin coloration on the cornea of his butt.

The subject variety is referred to on the basis of photographs where it is

No. 1 Figure 5A shows the stalk and foliage of corn, a

No. 2 Figure 3A shows the emblem with main and auxiliary branches, a

No. 3 Figure 5a shows the ripe, ruptured, broken tube, and eyes.

The present invention is directed to inbreeding, starting from simple hybrids of two original PIONEER lines, as a variant of the 354 varieties, in seven self-fertilization and selection cycles. The obtained grain maize has an FAO number of 220, a unit heat demand of 676 'C before flowering, and 70-90 ° C less than 354 varieties. Stem and rootstock with good yield, good grain texture and high specific weight.

In their subjects, the anthocyanin coloration of the anthers is absent or very faint, the stinging time is moderate, and the anthocyanin coloration of the stigmas is absent.

There is no closed anthocyanic ring at the base of the coat of arms of the tassel and the anthocyanin coloration of the ear coat is missing or very faint.

The anthocyanin coloration of the stems is medium, while the anthocyanin coloration of the foliage is absent or very faint in the center of the plant. The coat of arms is moderately branched, and the plant, together with the coat of arms, is now ⁵ gas. The tube is located low on the stem, especially with respect to the 354 variety. The cob is medium in length and has no anthocyanin.

The tube is short, cylindrical in shape, has many rows of eyes, equine tooth, and has a crown of ¹⁰ orange yellow eyes.

The main advantage of the present invention

- good yield,

- good grain, high specific weight grain,

¹⁵ pips for resistance to stem and rooting, and

- increasing the variety of the ripening group.
