BACKGROUND OF THE INVENTION The present invention relates to a two-line hybrid maize of the Marietta variety, derived from a cross of PHRE-1 xPHR-25, for the production of hybrid seed for maize production.

The two-line hybrid maize of the Marietta variety is produced by crossing the Pioneer lines bred with PHRE-1 and PHR-25. The new hybrid is 10 cm lower than the Dea, and the eye is of the tooth type.

The aim of breeding is to create a new single-cross hybrid, in which the heterosis effect is reflected in the high grain production ability.

The two-line hybrid maize of the Marietta variety is described in the UPOV TG / 2/4 system based on its morphological characteristics and phenological properties:

beginning Early-medium anthocyanin coloration of anthers medium anthocyanin staining of stigma weak the anthocyanin ring on the coat of arms based on the cornea weak anthocyanin coloration of stem flavors missing v. very weak anthocyanin coloration of the leaf pod missing v. very weak height of plant together with coat of arms medium

main stem height and plant height ratio high stem length on short to medium tube number of eyes many types of eyes equine crown color yellow-orange cob anthocyanin coloration

The two-line hybrid maize of the Marietta variety, with its high grain production capacity, expands its variety advantageously.

Figure 1 shows a tube of a corn variety according to the invention.

Claims (1)

Patent Claim Point Two-line hybrid maize of the Marietta variety, derived from the PHRE-1 xPHR-25 cross, appears in early to mid-tide blooms, with the anthocyanin ring on the crest of the coat of arms 20 weak, with little or no anthocyanin at stalk and leaf pod, high stem relative to plant height, short-to-medium stem, yellowish-orange crown and anthocyanin color, the anthocyanin is moderately anthers and the stigma is slightly colored, the height of the plant is moderately high with the coat of arms, many rows of eyes are formed on the tube, and the eyes are of the equine type.
