Alkmene (apple)
It was developed between the years 1900 and 1949, by the Kaiser Wilhelm Institute in Müncheberg, Germany, by crossing the two cultivars 'Cox's Orange Pippin' and 'Duchess of Oldenburg'. The result is an early harvest apple (early mid season), which is very attractive, with a honeyed flavor similar to Cox's but slightly sharper. Its main use is for fresh eating.
