Abstract

A new variety of mandarin citrus, named "Winola", is distinguished by a triploid chromosome number (3n=27), anthers bearing pollen with low viability, fruit which is seedless, leaves which are thicker and stiffer than Temple, thorns borne mainly in the lower part of the tree and fruit which is predominantly inside the canopy. Winola resulted from a controlled pollination cross-breeding between Wilking as a seed bearing parent and Minneola as a pollen parent. The fruit surface is wrinkled with an orange-red color and bears conspicuous, but sparsely distributed rind oil glands. The thickness of the rind is medium to thick, and adherence of the flesh to the rind varies from strong to semiadherent to easy peeling depending on the root stock and fruit maturity. Neither areola nor navel are present, and the fruit flesh is juicy, aromatic and of excellent taste, with segments of the fruit being easily separated.
