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.
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]
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. Each plant receives ...
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years.

The progeny from that cross would then be tested for yield (selection, as described above) and mildew resistance and high-yielding resistant plants would be further developed. Plants may also be crossed with themselves to produce inbred varieties for breeding. Pollinators may be excluded through the use of pollination bags.
In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation was heterozygous and consistent. The offspring showed a combination of the phenotypes from each parent that were genetically dominant. Mendel's discoveries involving the F1 and F2 generations laid the ...
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]
