Irwin (mango)


The Irwin' mango is a commercial mango cultivar which was developed in South Florida. This variety has a smooth bright red colored fruit with sweet aroma along with juicy pulp. TSS was measured above 20%.

History

The original Irwin tree was a seedling of the Lippens cultivar that was open-cross pollinated with Haden, planted on the property of F.D. Irwin in Miami, Florida in 1939. The tree first bore fruit in 1945 and was named and described in 1949. The fruit gained commercial acceptance due to its good production, flavor, relative disease resistance, and attractive color. 'Irwin' has also been sold as a nursery stock tree for home growing in Florida.
Today, Irwin is grown on a commercial scale in a number of countries, including South Korea,, Japan, Taiwan, and Australia, where it was introduced in the 1970s.
The Irwin mango was first grown in Taiwan in 1962 by Cheng Han-chih in Douliuzai Village in the Yujing District of Tainan. In 1973, the government designated Douliuzai Village as a special mango cultivation zone. By the 1970s the residents of Douliuzai Village were known for their wealth due to mango cultivation. Cheng Han-chih is considered to be the godfather of Taiwan's lucrative modern mango sector. Irwin mangos have been the most popular mango in the Taiwanese market for 50 years.
Irwin trees are planted in the collections of the USDA's germplasm repository in Miami, the University of Florida's Tropical Research and Education Center in Homestead, Florida, and the Miami-Dade Fruit and Spice Park, also in Homestead.
