Abstract

The invention is directed to a new mango tree variety ‘FP2’ which is the mutation of the parent cultivar ‘FP1’. The mango tree produces medium a little red fruit on a yellow ground color, and matured in August. The fruit seems to be resistant to Anthracnose and good storage capacity. The flesh of the fruit is orange yellow, high juice content, low fiber content, low acidity, good taste with high sugar content. The core is small.

Description

Latin name of the genus and species of the plant claimed: The Latin name of the genus of mango is Mangifera. The Latin name of the species of mango is Mangifera indica.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a new variety of tropical mango.

2. Description of the Related Art

This inventor has a U.S. Plant Pat. No. 9,005 entitled Mango Tree FP1 (hereafter to be called ‘FP1’). He has repeatedly asexually reproduced by planting of the buds of ‘FP1’ in the ground at the Chia-Yi of Taiwan to form an orchard. Such asexual reproduction uniformly produces a fruit of the character described in the specification of the U.S. Plant Pat. No. 9,005. In 2000, he discovered in the orchard that the fruit of a mango tree only has ‘FP1’ mango's partial characteristic, which are not similar with the other ‘FP1’ fruit. The mango of the discovered variety is referred to as the ‘FP2’ mango. The new variety ‘FP2’ is a true mutation of the parent cultivar ‘FP1’. The claimed plant ‘FP2’was found from a sport in a cultivated area in Applicant's orchard. The age of the observed plant is 8 years old. The new variety of mango tree has been repeatedly asexually reproduced in this applicant's orchard at the Chia-Yi Hsien of Taiwan by placing budwood of ‘FP2’, on mango seedlings in April 2006. Such asexual reproductions consistently and uniformly produce fruits of the characteristics described in this specification.

SUMMARY OF THE INVENTION

The invention is directed to a new mango tree variety ‘FP2’ which is the mutation of the parent cultivar ‘FP1’. The mango tree produces medium a little red fruit on a yellow ground color, and matured in August. The fruit seems to be resistant to Anthracnose and good storage capacity. The flesh of the fruit is orange yellow, high juice content, low fiber content, low acidity, good taste with high sugar content. The core is small, and white color near 158C.

DETAILED DESCRIPTION OF THE INVENTION

The following is a description of the characteristics of the mango tree variety of this invention.

  • Tree:
      • Tree vigor.—Medium. The terminal growth during the winter is 15 cm, and during the summer is 30 cm.
      • Tree size.—Medium about 8 years old.
      • Tree type.—Long oval.
      • Height.—3 m.
      • Girth.—40 cm. The measurement tree trunk was taken at the height of 60 cm from the earth ground.
      • Maturity.—The fruit of the tree ripens in August.
      • Pollination.—Open pollinated.
      • Location.—Chia-Yi, Taiwan.
      • Pruning.—Twice a year. The first time is in spring, any time at its bearing. The bent flower stalk without fruits and the slim twigs should be cut out for easy management. The second time is in summer, any time after the harvest. The upward branches should be cut out for high productivity in the next season.
      • Bark.—Smooth.
      • Petiolate.—Tough, resistant to wind damage.
      • Bloom.—Early, on December, full blooming on February. The location at time of culture of the blooming season of the instant tree is in winter at the Chia-Yi Hsien located in the middle of Taiwan.
  • Leaf:
      • Length.—34.5 cm.
      • Width.—7.0 cm.
      • Thickness.—0.5 cm.
      • Color.—Both the upper and the lower leaf surface is green color near 136A.
      • Leaf type.—Large, oval-lanceolate, The tip of a branch is personate verticillate phyllotaxy.
      • Both upper and lower leaves' surface.—Glabrous and smooth.
      • Petiolate.—5.5 cm in length. The petiole's color is green near 136A. The petiole's surface texture is glabrous and smooth.
        The leaf's margin is entire, is not serrated. The apex shape of leaf is acute tip. The base shape of the leaf is lanceolate.
        The leaves are simple, exstipulate, alternately arranged, 34.5 cm in length. The petiole is 5.5 cm in length, always swollen at the base. It is grooved on the upper side. As the leaves are arranged very closely at the tips they appear to be whorled. The shape of leaves is lanceolate. The apex ranges from acuminate to nearly rounded. The margin is usually entire, sometimes slightly undulated and wavy, rarely twisted or folded. The length and breadth varies from 12 to 45 cm and 2 to 12 cm, respectively, depending on variety and growth. The secondary veins are quite prominent, and in some of the varieties range from eighteen to thirty pairs. The upper surface is shining and dark green while the lower is glabrous light green. The leaves appear in flushes. They are flaccid and pendulous when young. The color of young leaves generally varies form variety to variety, generally being tan-red, pink, yellow-brown in color. As the leaf grows, its color changes from tan-red to green, passing through many different shades and becomes dark green at maturity.
        The leaves have fibres and crackle when crushed. They have strongly smell of turpentine (some cultivars do not smell). The leaves contain a good amount of mangiferin (xanthone). In India, it was obtained as “Indian Yellow” from the cow's urine because cows were fed exclusively with mango leaves and ultimately excessive feeding on leaves lead to the death of the animal.
  • Panicle:
      • Inflorescence.—Conic, axil and terminal, the inflorescence length being about 15-40 cm, normally having ramify 2 or 3 times and the last ramification has 3 flowers as an umbrella. Every inflorescence has 500-3,000 flowers. The inflorescence length is 15-40 cm. The diameter of the flower is 0.25-0.3 cm. The length of the flower is 0.2 cm.

      • Petal.—5 pieces. The petal's average size is 0.2 cm, yellow color near 13A.
      • Stamen.—5 pieces, but normally only 2 or 3 stamen in full growth could disseminate pollen. And, the shape of a grain of the pollen is oval. The color of the pollen is yellow near 13A.
