Mango tree named ‘Magriver’

Abstract

A new and distinct variety of mango tree (Mangifera indica), Magriver, is disclosed which is distinguished by the production of heavy and consistent crops of fruit that are 168 g average weight, having a rounded base, stool stem inserted obliquely in a level manner, a rounded apex with a small lateral beak, and undulating surface. The tree is corpulent and its shape is erect, open, and branched. It is a vigorous tree and highly productive, with good disease tolerance. The fruit skin color is bright yellow with small pink or crimson blush, and thin tender and adhesive skin. The flavor is excellent, rich and aromatic, with a strong component of sugar cane, a creamy smooth texture with a brix of 15.51 and a long flavor-life in storage. The new Magriver tree is adapted to soils with salinity.

Claims

Description

DESCRIPTION OF THE PHOTOGRAPHS

(1) This new mango tree is illustrated by the accompanying photographs which show the entire tree, the inside and outside of the fruit, and the seed; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 2-year-old tree grown in Colombia, South America, taken in July 2017.

(2) FIG. 1 shows the entire tree.

(3) FIG. 2 shows the exterior of the immature and mature fruit.

(4) FIG. 3 shows the interior of the mature fruit.

(5) FIG. 4 shows the seed.

DESCRIPTION OF THE NEW VARIETY

(6) The following detailed descriptions set forth the distinctive characteristics of Magriver. Trees of the new mango variety have not been observed under all possible environmental conditions. Observations and measurements were taken on a 2-year-old tree grown outdoors in Colombia, South America, in July 2017. The farm where Magriver was selected and asexually propagated is affected by saline soils and high amount of chlorides and sulfates of calcium, magnesium and sodium. The saline soils and higher pH do not affect the new Magriver trees as compared to other new introductions to the area. The soils are 32% clay, 57% slime, and 11% sand, and the temperatures range from 23 C. to 38 C. Precipitation in the region varies throughout the year, with the lowest in February with 0 mm and the highest in October with 192 mm. The annual average relative humidity varies between 79% and 81%. Color readings were taken under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2016 edition).

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETY

(8) The new Magriver variety differs from the parent tree Hilacha (unpatented) in that Magriver produces fruit that are oblong to oval with a rounded base and no cavity, having an average weight of 168 g and a brix value of 15.51, and is suitable for rootstock in saline soils, while Hilacha produces fruit that varies in shape with some being more elongated and some rounded, with a cavity in the base, having an average weight of 150 g and a brix value of 19, and is not suitable for rootstock in saline soils. Additionally, the flowers, fruit, and branches of Magriver have low symptoms of anthracnosis (Colletotricum gloeosporioides), whereas the flowers, fruit, and branches of Hilacha are extremely sensitive to the disease when grown under the same environmental conditions in Colombia.

(9) Magriver differs from commercial mango variety Haden (unpatented) in that Magriver produces small fruit with an oblong to oval shape, whereas Haden produces medium to large fruit with an oval to round shape.
