Description

BACKGROUND OF THE INVENTION The present invention relates to a novel hybrid maize, more particularly an inbred and maize hybrid having predetermined properties.

The well-known corn hybrid usually grows to about 7-9 feet (2.1-2.7 m) tall and each plant grows one or two tubes. The tube usually grows at one-third of the plant height or 2.53.5 feet (0.75-1.05 m) above the ground. The plant, while growing a large tube, has a considerable amount of leaves and stems. This results in poor mechanical stability, as the heavy tube is about 3 feet (1 m) from the ground, the leg is 6 feet (2 m) and the coat of arms is located above it. Various attempts have been made in the past to develop a strong stem and branch the secondary root system, thus reducing stability problems. These efforts have increased the mechanical stability of the corn, but stormy winds and rain can cause great damage to the corn fields.

Although the use of maize hybrid has significantly increased crop yields, it has not been recognized that further significant benefits can be gained from hybridization. Efforts should therefore be made to improve the performance of conventional hybrid maize through genetic and environmental interventions.

The object of the invention is to significantly increase the yield of maize. An April 17, 1974 article in The Wall Street Journal, entitled "Super Bean Research," emphasizes that soybeans are difficult to hybridize and are significantly behind corn in terms of milk yield. Between 1950 and 1973, soybean yields increased from 21.8 to 27.8 rubles per 1 lb.

Other valuable traits can be developed by methods of plant cultivation and gene manipulation. For example, the vitality of a plant during germination plays a major role in germination, as well as in the early setting and greening of sowing.

The present invention relates to a novel corn hybrid which, among other things, has the above advantages.

The present invention relates to a new Fj generation hybrid maize plant DK 524. Seeds of the above hybrid were deposited under American Type Culture Collection, 12301 Parklawn Drive, Rockville, Maiyland 20852 under ATCC 40180.

The present invention also relates to a new hybrid 1 maize DK 524 and a new seed obtained therefrom.

Also included within the scope of the invention are cells that have produced a DK 524 maize hybrid by culture and selection.

For the production of the maize hybrid of the invention, the inbred line 78010 developed by Dekalb Pfizer Genetics may be used as female and the 78060A inbred line developed by Dekalb Pfizer Genelics as the male subject.

The two inbred lines 78010 and 78060A are planted in close proximity to each other for pollination. Planting can be done in alternating rows, blocks or any other system. Plants from the two inbred lines are allowed to grow until flowering. The plants can be thinned as needed in about 3 leaves and treated with growing manure and / or other agrochemicals. During flowering, all plants derived from female inbred lines 78010 are removed. This is usually done by hand, but can also be done with proper machine equipment. Alternatively, chemical sterilization involves the transformation of a female subject by cytoplasmic delivery of a male sterile property. Then, both inbred vo5 larvae are allowed to evolve and to be cross-pollinated by the wind, as is the case with grasses and thus with maize. Of course, only pollen from male 78060A inbred lines is suitable for pollination, as all female 78010A belle0 lineages have been removed. Accordingly, the areas where the hybrid of the present invention is grown should be well isolated from other corn-producing areas to avoid contamination of pollen polluting the environment. The techniques for isolation are common in maize cultivation and well known to those skilled in the art.

Plants from both inbred lines are allowed to grow, but only tubes from female inbred lines 78010 are harvested to produce the FK hybrid maize grain DK 524 of the present invention. Tubes from male inbred lines may also be harvested but not used as hybrid seeds.

> For the production of F1 hybrid maize according to the invention, the resulting grains are planted in the following season. All parts of the resulting hybrid plant DK 524, including the root, stem, leaf and all flowering parts, including pollen itself, are within the scope of the present invention. Also included within the scope of the invention are hybrid plant cells DK 524 which can be transformed into plants by culture, selection or regeneration. Such procedures are described in C. E. Green and C. A. Rhodes, "Plant Regenerate in Tissue Culture of Maize" (Mazeze for Biological Research, 1982; W. F. Sheridan, Plant Molecular Biology Association, Charlottesville, Virginia, pp. 367-272).

The present invention includes within its scope the mature DK 524 F! grains produced by hybrid plants. DK 524 H hybrid maize is planted, the hatched hybrid plants are allowed to grow to maturity, and the tubes are harvested by mechanical means in the usual way. Numerous studies have been carried out on hybrid plants and grown grains. The results were compared with the Dckalb-Pfizer Genetics TI000 hybrid and the Pioneer Hi-Bred International P3732 hybrid, which show similar moisture content in the vat and thus allow a proper comparison.

From the results of the table, it can be seen that the new hybrid DK 524 has advantages over the similar and generally high quality T1000 hybrid. The new version of the present invention shows better results in terms of yield, germination capacity, early onset and greening. These benefits would unexpectedly and surprisingly bill you for the crossing of the two aforementioned parent units.

In addition to the properties shown in Table 1, the following properties of DK 524 were observed:

Although the invention has been described in detail and in all respects, it will be apparent to those skilled in the art that various changes and modifications are possible without departing from the spirit and scope of the invention.
