Abstract
A cherry tree, Prunus avium, having the variety name `Early King`, is described. `Early King` is large, vigorous, upright, dense, vase-formed, and hardy. It is foliated with large, ovate, medium-thick, smooth, abruptly pointed, dark green leaves having a crenate to coarsely serrate margin, a petiole of medium length and thickness, and medium sized, alternate, reniform, red glands. `Early King` blooms from hardy, free buds of medium size and length about two days before `Bing` and two days after `King` varieties of cherry tree. The flowers are white and of medium size. `Early King` is a regular and very productive bearer of early and evenly ripening, semi-freestone, uniform, medium-sized fruit that is broadly compressed towards the slight to non-existent suture. `Early King` requires approximately 600 chill hours for setting fruit compared to approximately 1,000 chill hours required for `Bing`. The fruit ripens about three to four days before `King` and ten to eleven days before `Bing` and has a thick to medium thick, tough skin which is dark purple when eating ripe, and red flesh.
