Description

BACKGROUND OF THE INVENTION The present invention relates to a disease resistant and tolerant sunflower parent lineage derived from a synthetic population that can be used as a disease resistant parent partner in the production of hybrid sunflower.

- 2 The IR-134 male lineage was bred from a synthetic population using a combination of inbreeding, pedigree selection, half-seed method and half-sib selection.

During inbreeding, selection was made primarily to increase disease resistance and tolerance.

The object of the present invention was to breed a paternal line that is plasmopara-, sunflower-moth and satir-resistant, highly tolerant to phomopsis and macrophomina pathogens, and has tolerance to sclerotinia and botrytis. In addition to collecting genes for disease, our goal was to increase the oil content to about 50% and accelerate plant development through very early flowering.

The IR-134 sunflower father line was bred from a synthetic population and is described in the UPOV TG / 81/3 system based on its morphological characteristics and phenological characteristics:

hypocotyl anthocyanin coloration leaf size (cm) leaf shape leaf color leaf anthocyanin coloring leaf surface leaf blistering leaf tooth fineness leaf tooth regularity

- medium or strong

- very small (157 cm)

- heart shaped triangle

- medium green

- Missing

- there is

- weaker than average

- medium

- shape of cross-section of irregular leaf on leaf wing (leaf shoulder) leaf angle of lateral veins height of leaf apex relative to leaf base (2/3 of stem)

- straight

- wingless

- acute angle

- angle between very low stalk and lower part of stalk (40-50 mm long in middle of stalk)

- medium

leaf stem length (cm) - short (12.5 cm) trough shape of leaf stalk (1/3 stalk) - turtle anthocyaninism of the petiole - no stem hair 5 cm below the plate - medium

number of leaves on the stem

- few (21.5 pcs) stems diameter flowering time

- thin

- very early

number of tongue flowers many (60 pcs tongue flower shape - oblong tongue flower edge - smooth tongue flower color - golden yellow tube flower color - yellow anthocyanin coloration of stigma on tubular flower - weak the number of nest scales on the inflorescence - a lot of duration of flowering - 16-18 days

on cotyledon the shape of the cotyledons - on the elongated cotyledon the cyan coloration of the cotyledons on the anthrax plant the position of the primary cotyledons relative to the cotyledons - supernatants cm · cotyledon position - cotyledon (upper) (cotyledon) natural height of plant (cm) - almost low (133 cm) degree of bending of plant

- medium

- there is branching type on the plant type length of cutter type shape of cutter thickness thickness of cutter type cutter type marble pattern

- peak

- short (10.8 mm)

- oblong

- medium

- black

- no

- the color of the strip is on the cut

- position of striping on gray-dark gray meadow edge - on edge and side

The advantage of the IR-134 sunflower lineage is that fast-growing, very early-flowering plants are resistant to sunflower molar, satiric and plasmopara pathogens, are highly tolerant to phomopsis and macrophomina pathogens, and selerotinia and botrytis and they are tolerant. The oil content is 48-49%. The paternal lineage can translate disease resistance genes into hybrid sunflower with it.
