Description

Objective of the Invention: An inbred line of maize for the production of early cold tolerant silage maize hybrids, which hybrids have rapid grain filling and water release, and have stable growing times and fertility under cool climates. 5

The inbred line HMv 45, which is the subject of the invention, was patented in France by Maisadour with the consent of the Martonvásár Agricultural Research Institute. The purpose of the Hungarian application is to extend and grant protection to Hungary 10.

Maize inbred lines suitable for the production of early cold-tolerant silage maize hybrids are widely known. Such as line HMv 5302, whose stem is of medium height, vegetative growth, the leaves of the juvenile are strongly erect, twisted, their tips are pointed, the color of the juvenile leaves is light green, yellowish-green, poisonous in adulthood, the crest is many lateral, strongly dense , the eyes are very large, floury, soft, the clump is shallow, the color of the crown is typically citrusy yellow.

(HMv line 5302 was granted final patent protection in Hungary in 1992.)

The filed line provides FAO 200-300, well-drained, early, fast-graining and water-release hybrids that are resistant to leaf rust and stem fusarium in a cool, rainy climate.

These corn lines, as well as other known lines, are not early enough, or they do not reach the desired level of cold tolerance, or, under cool climates, breeding times are delayed and the productivity of their hybrids is not sufficiently stable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inbred line of early-maturing, fast-seeding and dehydrating maize which is widely used and has stable hybrids in cool climates.

BACKGROUND OF THE INVENTION The present invention relates to an early-maturing, medium-growing, generative inbred maize line having anthocyanin stems, highly anthocyaninous, especially in cool climates, budding of young leaves, later green to greyish, later ash-green, lack of anthocyanins in anus, stubble and cotyledon, lack of anthocyanin ring closed at base of earcap, coarse coarse, loose coarse at intermediate position, ends curved longer than caudal length, the shape of the tube is cylindrical, the tip is conical, the color of the eyes is matte yellow, and there are characteristic liver spots on the apex of the eyes.

The characteristics of the inbred line of the present invention will be described in more detail below.

The advantage of the line is that its genetic background and combining ability allow it to be widely used in hybrid production.

Another advantage of the line is that it is a generous pollen producer, so it is advantageous to use as a paternal parent.
