Description

SUMMARY OF THE INVENTION An object of the present invention is to provide an inbred line for the production of cold tolerant corn hybrids, which hybrids are well condensed and well adapted to the cool, rainy climate of the ocean.

The inbred line of the invention has been patented in France by Maisadour with the consent of the Martonvásár Agricultural Research Institute. The purpose of the Hungarian application is to extend or obtain patent protection in Hungary.

Inbred lines for producing cold tolerant silage and grain 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 leaves is light green, yellowish-green, the poison is adult, many lateral, strongly dense, stamens and cob anthocyanin, large tube, conical, very large eyes, floury, soft, with a shallow trunk, and a characteristic lemon-yellow color.

This corn line and other known lines are not sufficiently cold tolerant. Due to the persistent low temperatures along the ocean, growing times are prolonged, fertility of their hybrids fluctuates, or they are not resistant to leaf diseases in a humid climate. Figure 1 shows the identity of a plant of the species HMv 230, a

Figure 2 shows the corn tube.

SUMMARY OF THE INVENTION The present invention relates to a maize inbred line which is widely used for the production of cold tolerant silage and grain maize hybrids, the hybrids of which can advantageously be thickened, under cool climates, with long growing times and stable fertility.

BACKGROUND OF THE INVENTION The present invention relates to a mid-matured, vegetative-growth, medium-high inbred line having anthocyanin stem, strongly anthocyaninous under cool climates, broad, medium-green or angry-green, with little lateral, dense, caudal, anthers, stubble, cob anthocyanin, tubes perched on long stalk that bends when matured, tube slightly tapered, tube sharpened sharply, eye type equine, large circumferential, with shallow cape, eye color often dark orange the copper part of the eyes is of medium yellow color.

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

- germination, emergence in cold soil: fast

- initial development of juveniles: rapid

- stem of young plant in cool climates: anthocyanin

- color of the mature plant: medium green, angry green

- height of the adult plant: 145-155 cm

- development of the stem of the adult stem: 12 floors

- state of leaves: erect

- leaf surface: straight

- leaf ends: soft, gradually sharpened

- leafiness of the pods: slightly hairy

- Coat of arms: Intermediate

- date of the coat of arms: medieval

- date of birth of the stigma: middle age

- color of anthers: anthocyanin

- color of stigma: anthocyanin

- color of cob: anthocyanin

- tube length: 14-15 cm, tube bent

- tube shape: cylindrical, slightly tapered, the tip of the tube sharpens sharply

- tube thickness: 3.8 to 4.0 cm

- number of rows of eyes: 14-16

- Line of eyes: straight, unordered

- eye type: hard dent, with a large circumference (hard-toothed), shallow hump

- color of the back of the eyes: dark orange with a reddish tinge

- color of the copper part of the eyes: medium yellow

- Length of eyes: 0.8-0.9 cm

- width of eyes: 0,5-0,6 cm

- Eyes thickness: 0.5-0.6 cm

- Ball and fiber angle resistance: good

- MDMV and BYMV resistance: slightly susceptible

- resistance of tube fusarium: good.

The filed line provides FAO hybrids with a 200-300 growing time, cold tolerant, well-thickened, stable growing time and productivity.

The advantage of the line is that its combined ability and genetic background allow its wide application.

Another advantage of the line is that it produces abundant pollen and produces good quality seed, so it can be advantageously used as both a paternal and maternal partner.
