Apple tree named ‘MAIA-T’

A new and distinct variety of apple was identified from a population of seedlings derived from an open-pollinated ‘Honeycrisp’ block. The new variety, named ‘MAIA-T,’ is distinct from ‘Honeycrisp’ as ‘MAIA-T’ ripens mid-September, 2 weeks after ‘Honeycrisp.’ Unlike ‘Honeycrisp,’ ‘MAIA-T’ has purple skin, yellow ground color, and considerable russet. ‘MAIA-T’ fruit are medium sized, crisp, with more complex, sweet-tart flavors than ‘Honeycrisp.’ ‘MAIA-T’ does not maintain crisp texture in 35° F. storage for as long as ‘Honeycrisp.’

Latin name of the genus and species of the plant claimed: Malus x domestica.

Variety denomination:

Variety denomination: ‘MAIA-T’.

BACKGROUND OF THE INVENTION

A new and distinct variety of apple was identified from a population of seedlings derived from an open-pollinated ‘Honeycrisp’ (U.S. Plant Pat. No. 7,197) block. This pollination was sanctioned as a part of the Midwest Apple Improvement Association apple breeding project. ‘Honeycrisp’ and other select varieties were cultivated with the intention of progeny testing open-pollinated seedlings. This superior seedling tree was identified from this progeny test at Pataskala, Ohio.

The seedling tree was planted as a 1-year-old tree at a commercial fruit orchard in Pataskala, Ohio in 2001 and grown among a population of several hundred siblings. Evaluations of fruit quality and tree growth parameters were begun in 2005 and this seedling was identified over several years as superior based upon tree growth habit, precocity, superior fruit quality, and harvest time. Utilizing grafting reproduction, the new apple tree variety was asexually propagated by Mitch Lynd in 2010 in Pataskala, Ohio and has been observed to remain true to the description set forth herein, through successive generations.

The new variety, named ‘MAIA-T,’ is distinct from ‘Honeycrisp’ as ‘MAIA-T’ ripens mid-September, 2 weeks after ‘Honeycrisp’ (FIG. 1). Unlike ‘Honeycrisp,’ ‘MAIA-T’ has purple skin, yellow ground color, and considerable russet (R.H.S. Color Chart Red-Purple 60A, Yellow-Orange 16B, and Yellow-Orange 22A, respectively). ‘MAIA-T’ fruit (FIGS. 2 & 3) are medium sized, crisp, with more complex, sweet-tart flavors than ‘Honeycrisp.’ ‘MAIA-T’ does not maintain crisp texture in 35° F. storage for as long as ‘Honeycrisp’ (FIG. 1).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographs show typical specimens of the new variety depicted in color as true as is reasonably possible. ‘MAIA-T’ photographs were taken at Pataskala, Ohio. FIG. 1 was created from harvest data from Pataskala, Ohio, and storage data from Carrollton, Ohio.
