The Kinnow orange is a high-yielding mandarin hybrid, celebrated for its intense juiciness and rich, sweet-tangy flavor. Developed in 1935 by Howard B. Frost at the University of California, it is a cross between the 'King' (Citrus nobilis) and 'Willow Leaf' (Citrus x deliciosa) cultivars. Today, it is a staple of winter fruit markets, primarily cultivated in the Punjab regions of India.
