Sharwil

Sharwil is popular with commercial growers, and has a long and heavy bearing season throughout the winter months of November to February. The fruit is medium sized and pear-shaped with a small seed, high oil content, and a green rough skin. Sharwil is an amazingly consistent bearer, and is the only variety allowed by the USDA to be shipped to other states.

Predominantly Guatemalan, with some Mexican race genes, ‘Sharwil’ was developed in 1951 by Sir Frank Sharpe at Redland Bay, southern Queensland. The name “Sharwil” is an amalgamation of Sharpe and Wilson (J.C. Wilson being the first propagator). Scions were sent from Australia to Hawaii in 1966. A medium-sized fruit with rough green skin, it closely resembles the ‘Fuerte’, but is slightly more oval in shape. The fruit has greenish-yellow flesh with a rich, nutty flavor and high oil content (20–24%), and a small seed. The skin is green when ripe. It represents more than 57% of the commercial farming in Hawaii, and represents up to 20% of all avocados grown in New South Wales, Australia. It is a regular and moderate bearer with excellent quality fruit, but is sensitive to frost. Disease and pest resistance are superior to ‘Fuerte’.
