Kinnow

The kinnow is a variety of citrus fruit cultivated extensively in Pakistani and Indian Punjab Province. It is a hybrid of two citrus cultivars — "King" (Citrus nobilis) x "Willow Leaf" (Citrus deliciosa) — first developed by H. B. Frost at the Citrus Research Centre of the University of California, Riverside, USA. After evaluation, the kinnow was released as a new variety for commercial cultivation in 1935. In 1940, Punjab Agriculture College and Research Institute, Faisalabad (former Lyallpur) (Pakistan), introduced the kinnow. In India this variety was introduced by J. C. Bakhshi in 1954 at the Punjab Agricultural University, Regional Fruit Research Station, Abohar. It has become an important variety in the Punjab provinces of both India and Pakistan, occupying a major part of the area under cultivation for fruit crops.
