Malus niedzwetzkyana (but now Kazakhstan) during his 1897 expedition. Hansen began two breeding programs based on this unusual fruit, one aimed at developing a cold-hardy cooking and eating apple, and the other aimed at developing ornamental crabapples. His efforts resulted in the Almata apple and the Hopa crabapple, among other varieties. Some of these apples, as well as "M. niedzwetzkyana" itself, are being used for small-scale commercial production of rosé apple ciders. Malus niedzwetzkyana Malus niedzwetzkyana, or Niedzwetzky's apple, is a kind of apple native to certain parts of China, Afghanistan, Kazakhstan, Kyrgyzstan, and Uzbekistan noted for its red-fleshed, red-skinned fruit and
Malus are borne in corymbs, and have five petals, which may be white, pink or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar). Apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); all are self-sterile, and (with the exception of a few specially developed cultivars) self-pollination is impossible, making pollinating insects essential. Several "Malus" species, including domestic apples, hybridize freely. They are used as food plants
