MAIA-1

A Honeycrisp × Fuji seedling bred by a growers' association; only Honeycrisp was planted more in Michigan in 2020–22

History

MAIA-1 was bred by MAIA, an association that commercial growers founded in the mid-1990s to raise apples suited to the American Midwest2. Any grower may join for a yearly fee and royalties on the trees; the members make the crosses, plant and assess the seedlings and report on them, and varieties are released by consensus2.

Honeycrisp, the seed parent, was crossed with Fuji at Pataskala, Ohio, in 19991. The seedling was planted at Wabash, Indiana, in 2001 among several hundred siblings; assessment began in 2005, and over several years it stood out for its growth, early cropping, fruit quality and keeping1. Tested as MDD5-443, it was propagated by grafting at Wabash in 20081. A plant patent applied for in August 2012 was granted on 1 July 2014 under the denomination MAIA1, naming William Dodd, David Doud, John Mitchell Lynd and Gregory Miller as inventors1. It is sold under the trade mark EverCrisp2,3, and Penn State Extension calls it the association’s most popular variety2.

By the autumn of 2020 MAIA reported that 1.8 million trees had been planted in the United States since its release3. Under an international testing agreement, members of the International Pome Association in Chile and New Zealand had begun commercial plantings, and partners in South Africa, Australia and Italy were testing it3. Michigan’s fruit inventory counted 580,000 trees under its trade mark in 2022, out of 17.6 million apple trees in the state; 350,000 of them had been planted in 2020–22, more than of any other listed variety except Honeycrisp4.

The fruit

The patent describes a medium-sized, roundish-oblate fruit of 180–220 grams and 75–80 mm across, with orange-red skin lightly striped over an orange-white ground and little given to cracking1. The yellowish-white flesh is firm, very crisp, breaking and juicy, sweet and aromatic1. In a comparison in November 2010 it was firmer than either parent and had red over 90 per cent of its skin, more than either, with 15.6 per cent soluble solids against 14.3 for Honeycrisp and 17.2 for Fuji1.

It ripens in mid-October, six to eight weeks after Honeycrisp; between 2008 and 2011 it was picked from 17 to 25 October1. It keeps long, both in cold storage and at room temperature1.

Growing

The tree is less vigorous than Fuji’s, with a more open canopy and many more fruiting spurs on two-year-old wood1. It flowers about a week after Fuji, with Golden Delicious, and needs a diploid pollinator in flower at the same time1; its S-alleles are S1 and S24, so Golden Delicious can pollinate it3. It is susceptible to scab, powdery mildew and other fungal diseases, has slight resistance to fire blight, and its fruit is prone to soft rot caused by Penicillium expansum1. An extension educator in Massachusetts found that it “appears particularly susceptible” to Marssonina blotch, as are both its parents3. MAIA advises against chemical thinning, preferring pruning and hand thinning, and warns that fruit borne at the tips of long, limber branches colours poorly3.

Where the sources disagree

  • Bearing. The patent records annual cropping1; an extension educator in Massachusetts warns that over-cropped trees can become somewhat biennial3.
  • Tree numbers. MAIA’s 2020 report says both that its millionth tree was planted that spring and that 1.8 million had been planted in the United States since its release3.
