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.
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.

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.
Flower constancy favors flower pollination, that is, pollinators that are flower constant are more likely to transfer pollen to other conspecific plants. [8] Also, flower constancy prevents the loss of pollen during interspecific flights and pollinators from clogging stigmas with pollen of other flower species. [2]
Plants have a number of different means to attract pollinators including color, scent, heat, nectar glands, edible pollen and flower shape. Along with modifications involving the above structures two other conditions play a very important role in the sexual reproduction of flowering plants, the first is the timing of flowering and the other is ...
Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant. The main characteristics which facilitate cross-pollination are: Herkogamy : Flowers possess some mechanical barrier on their stigmatic surface to avoid self-pollination, e.g. presence of gynostegium and pollinia ...
The Pink Lady/Cripps Pink apple isn’t a new variety — it was created back in the 1970s by British-Australian horticulturalist John Cripps, who had the idea to cross-pollinate Golden Delicious ...
SugarBee (CN121) [1] is a cultivated apple variety or cultivar discovered by Chuck Nystrom in the early 1990s at his orchard in Worthington, Minnesota. [2] It is believed to be a hybrid between a Honeycrisp and another, unknown variety. [3] Its name is in recognition of the role played by bees in open pollination, making the variety possible. [4]
