The variety was discovered by Chuck Nystrom in the early 1990s and developed in Minnesota, and is believed to be the result of an accidental cross-pollination between a Honeycrisp and another, unknown variety. [2]
The MN55 cultivar apple developed by David Bedford, a senior researcher and research pomologist at the University of Minnesota's apple-breeding program, and James Luby, PhD, professor, Department of Horticultural Sciences, Horticultural Research Center, is a cross between Honeycrisp and MonArk (AA44), a non-patented apple variety grown in Arkansas.
Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [ 1 ] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set.
Trademarked as EverCrisp, the MAIA-1 variety is a cross between two existing apple cultivars: the Honeycrisp and Fuji. [2] Originally produced in Ohio, EverCrisp has since expanded to apple-growing regions across the Midwest in Michigan, Illinois and Indiana, in the Northeast in Pennsylvania and New York, and in the Northwest in Washington.

Anthecology, or pollination biology, is the study of pollination as well as the relationships between flowers and their pollinators. [1]: 8 Floral biology is a bigger field that includes these studies. Most flowering plants, or angiosperms, are pollinated by animals, and especially by insects. [2]
However, as opposed to 'complete' or 'absolute' SI, in CSI, self-pollination without the presence of competing cross pollen, results in successive fertilization and seed set; [45] in this way, reproduction is assured, even in the absence of cross-pollination. CSI acts, at least in some species, at the stage of pollen tube elongation, and leads ...
The lengths of stamens and pistils in heterostylous flowers are adapted for pollination by different pollinators, or different body parts of the same pollinator. Thus, pollen originating in a long stamen will reach primarily long rather than short pistils, and vice versa.
Pollination by a specialist can result in high flowering synchrony, as asynchronous flowering can result in erratic attraction of a specialist to a site. [19] Showy floral displays tend to attract pollinators, [20] [21] and synchronous flowering can attract more pollinators to a population. High pollinator visitation to populations with high ...
