Notes and observations:
Kinnow, a King-Willowleaf mandarin hybrid, was developed at the University of California Research Center, Riverside by H. B. Frost in 1915 and released in 1935. Kinnow is the most widely-planted mandarin in Pakistan. The tree grows vigorously and has an upright form, with a strong tendency to alternate bearing. The fruit is oblate with a smooth orange rind that does not peel especially well for a mandarin. The flesh is orange, seedy, and has a rich distinctive flavor. Kinnow is mid-season in maturity and holds well on the tree.
Description from The Citrus Industry Vol. 1 (1967):
"Fruit medium in size, moderately to slightly oblate; both base and apex flattened or slightly depressed. Rind thin, rather adherent for a mandarin but peelable, tough and leathery; surface very smooth and glossy, sometimes faintly pitted; color yellowish-orange at maturity. Segments 9 to 10, firm, separating fairly easily; axis solid to semi-hollow. Flesh color deep yellowish-orange; very juicy; flavor rich, aromatic, and distinctive. Seeds numerous, polyembryonic, and cotyledons pale greenish-yellow. Midseason in maturity (about like Dancy). Fruit holds well on tree with little puffing.
Availability: Commercially available in California through the Citrus Clonal Protection Program.
