| Abstract: |
A new and distinct cultivar of African violet named Improved Indiana characterized by its single pink flowers with darker center; strong, upright flower stems that curve slightly toward the center to form a compact bouquet above the leaves; medium green, round to heart-shaped leaves; profuse flowering, vigorous and compact growth habit, flowering 10-11 weeks after potting, and its long lasting and non-dropping flowers. |
| Claim: |
I claim:
1. A new and distinct cultivar of African violet named Improved Indiana, as described and illustrated, and particularly characterized by its single pink flowers with darker center; strong, upright flower stems that curve slightly toward the center to form a compact bouquet above the leaves; medium green, round to heart-shaped leavesl; profuse flowering, vigorous and compact growth habit, flowering 10-11 weeks after potting, andits long lasting and non-dropping flowers. |
| Description: |
The present invention comprises a new and distinct cultivar of African violet plant, botanically known as Saintpaulia ionantha, and hereinafterreferred to by the cultivar name Improved Indiana.
The new cultivar was referred to during the breeding and selection process by the destination 58 pink and is a product of a planned breeding program. The basic objective of the breeding program was to create a new African violet cultivarimproving certain characteristics of the cultivar Indiana, disclosed in my U.S. Plant Pat. No. 4,296. The new cultivar was originated from a cross made by me in the controlled breeding program in Haffen, Federal Republic of Germany. The female, orseed parent was a cultivar designated K/39. The male, or pollen parent was a cultivar designated I/25.
Improved Indiana was discovered and selected by me as a flowering plant with the progeny of the stated cross in a controlled environment in Haffen, West Germany. Asexual reproduction of the new cultivar by leaf cuttings, as performed by me atHaffen, West Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.
Improved Indiana has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length. The following observations,measurements and values describe the new cultivar as grown in a 10 cm pot in Haffen, West Germany and Nashville, Tenn. under greenhouse conditions which closely approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Improved Indiana, which in combination distinguish this African violet as a new and distinct cultivar:
(1) Strong, upright flower stems curving slightly toward the center.
(2) Violet-shaped pink flowers with darker center.
(3) Each plant carries 8-10 and more upright flower stems each of which carries 8-10 and more flowers.
(4) Long lasting, non-dropping flowers.
(5) Vigorous and compact grower.
(6) Plant saleable 10 to 11 weeks after potting.
(7) Seed capsules push slightly through.
(8) Medium green, round to heart-shaped leaves.
(9) After maturity the flowers dry off, and remain on the peduncle without becoming infected by botrytis.
The new cultivar is most similar to, and was specifically intended to improve upon the characteristics of, my previously patented cultivar Indiana. In comparison to Indiana, the new cultivar is principally distinguished by its more compact andbetter growth habit, better blooming habit, lighter green foliage, as well as smaller and more funnel-shaped calyx.
The accompanying color photographic drawing shows a typical specimen plant of the new cultivar. The colors appearing in thephotograph are as true as possible with color illustrations of this type.
In the following description, color references are made to the Royal Horticultural Society Color Chart (RHS), except where general colors of ordinary significance arereferred to. Color values were taken under natural sunlight conditions at approximately 12 a.m. in Nashville, Tenn.
Botanical classification: Saintpaulia ionantha, Ramat., c.v. Improved Indiana.
Parentage:
Male parent.--I/25.
Female parent.--K/39.
Propagation: The new cultivar holds its distinguishing characteristics through successive propagations by leaf cuttings.
Plant: From 9 cm to 12 cm tall when grown in pots, and approximately 24-28 cm in diameter when fully grown.
Leaves.--General form: Round to heart-shaped. Diameter: 60-70 mm wide and 65-75 mm long. Texture: Leatherlike. Aspect: Hairy, slightly shiny. Veins: Upperside: well visible; underside: well pronounced, light green, shiny. Color (upperside):Yellow-Green Group 147 between A and B. Color (underside): Greyed-Green Group 194 C to D. Petiole: Strong upright, purplish brown, hairy.
Flowers.--Buds: Bell-shaped, 7-9 mm just before opening, pinkish green. Sepals: Five (5). Color: Green. Calyx: Shape: Funnel-shaped. Aspect: Spear-shaped, hairy. Peduncle: Character: Strong upright, hairy. Color: Purplish brown.
Individual flowers.--Size: 40-45 mm. Shape: Single violet-shaped. Color (upperside): From Red-Purple Group 73 A to 74 D. Under cooler temperatures and more intensive lighting, the pink tends to intensify. Color (underside): Red-Purple Group 74D and lighter. Borne: Each flower stem carries 8-10 and more flowers on strong, upright peduncles that are free standing above the leaves, thereby forming a compact bouquet. Flowering habit: Flowers 10-11 weeks after potting.
Reproductive organs:
Stamens.--Two (2). Anthers: 2 composed of 4 anther cells, seed capsule pushes slightly through.
Filmanets.--Yellowish green 3-4 mm long.
Pollen color.--Yellow Group 7 A.
Styles.--6-7 mm long, pink, base of ovary light green and hairy.
Roots: Normally developed, white when young, turning slightly brownish when older.
Disease resistance: Up to date, Improved Indiana has shown very good resistance to all major violet diseases.
General observations: Improved Indiana is a very attractive, vigorous and compact grower with medium green, round to heart-shaped leaves. A tight bouquet of flowers free standing above the leaves develops after approximately 10-11 weeks. Eachof the 8-10 and more strong flower stems carries 8-10 and more single pink flowers with darker center. The flowers are long-lasting and non-dropping and the seed capsules push slightly through.
