Mango tree named ‘K69’

Abstract

A new variety of mango tree (Mangifera indica), ‘K69’ is disclosed; distinguished by production of heavy and consistent crops with large, rounded fruit averaging 1,650 g.; purpure dark, smooth to slightly undulating waxy skin, resembling a large plum with apricot aroma, peach accents and coconut and mandarin hints. Mature fruit has a striking oxblood to chrysanthemum red peel color confluent over nearly the whole surface; immature fruits are beetroot purple with an ashen, waxy sheen. Orange buff flesh, firm and melting without fiber. Flavor is sweet, rich with peach, mandarin, and coconut accents and 17.0°±1 brix. The new tree has large leaves, is vigorous and upright in growth habit with potential for commercial use and its fruit is desirable for processing due to size and quality. Leaves, bloom, and fruit have good disease tolerance. Postharvest handling rated as good but reaction to hot water treatment is unknown.

(9) The new ‘K69’ variety differs from the parent tree ‘Kent’ (unpatented) in that ‘K69’ produces fruit that are uniform in shape where most fruit are oblong to oval with a rounded base and shallow cavity with an average weight of 1,650 g (58.2 oz). Immature fruits are beetroot purple with an ashen, waxy sheen, and when ripen turned to a striking oxblood to chrysanthemum red peel color confluent over nearly the whole surface. The tree is large, and vigorous with an upright growth habit, it has large leaves, and it is highly productive, with good disease tolerance. ‘Kent’ produces fruit average 600 g (21.2 oz) that varies in shape where some are more elongated and some are rounded, and the base color is green with yellow and some red blush. Additionally, the tree is vigorous, large, and compact canopy and heavily susceptible to Anthracnose (Colletotricum gloeosporioides) when grown under the same environmental conditions in the Redlands farming district of Miami-Dade County in South Florida, the United States of America.

(10) ‘K69’ differs from commercial mango variety ‘Haden’ (unpatented) in that ‘K69’ produces large fruit with red peel over the whole surface and is resistant to Anthracnose (Colletotricum gloeosporioides) whereas ‘Haden’ has bright yellow skin, with red blush, and numerous yellow dots and highly susceptible to Anthracnose (Colletotricum gloeosporioides) which make it a disadvantage for fruit processing.
