Abstract

FIELD OF THE INVENTION The present invention relates to early, cold-tolerant 3-line hybrid maize, which can be grown as grain and silage maize. Its characteristic feature is that the leaf of the plant blue is medium anthocyanin; the leaf is wavy, the tip is blunt, the color is lighter than the average, the lower leaves are slightly anthocyanic; on the coat of arms, the chaffs are green, with no anthocyanin ring on their base; the ports are yellow, but may later become slightly anthocyanic; the bib is also yellow, later the end is violet; the tube is cylindrical; the eye is toothed and yellow; the cob is medium red.

Description

BACKGROUND OF THE INVENTION The present invention relates to an excellent cold-break, 3-line early hybrid maize which, due to its dual utility, can be grown as both grain and silage maize.

The goal was to produce hybrid maize to expand the narrow 3-line hybrid range of the FAO ripening group to produce more productive than the existing Lg 2379 hybrid maize.

Bella hybrid maize has been shown to meet the above requirements. The Agricultural Certification Institute gave 7% higher grain yields in its breed trials than the Lg 2379 hybrid and proved to be stronger in stem. The hybrid is a high-growing, high-mass dentin-type. The high green weight and high dry matter content of the dry matter make it excellent for growing silage maize.

SUMMARY OF THE INVENTION It is an object of the present invention to breed a 3-line hybrid maize of the FAO 300 maturity group, which is capable of being cultivated early for cold-tolerant, high-stemmed and dual-use, that is, grain and silage maize.

According to the aim, the first leaf of the early, excellent cold tolerant hybrid maize has a medium anthocyanin, the tassel blooms are early, the stigma is weakly anthocyaninous, the cranial crest above the lowest lateral branch, the tube is cylindrical, the tube is cylindrical of medium intensity.

Figure 1 shows the characteristic tubular formation of the hybrid species.

The morphological description of the invention is described in UPOV TG / 2/4/1980. according to our guidelines, we'll explain in detail below.

Bella hybrid maize is characterized not only by its large grain and green yield, ie its dual utilization, but also by the fact that seed production is economical, since its basic mother hybrid has a high yield, ie it can produce 3-4 t / ha.

The high porosity of the underside allows good fertilization and safe seed production. Under irrigated conditions, this safety can be further enhanced.

Bella is extremely cold tolerant. The population is less susceptible to unevenness: it can tolerate denser populations well. It can compensate for the lack of stem with a larger tube or two tubes.

We have found that the protein content of the eye is higher than average.
