Abstract
At least 37 pink-fleshed sweet orange cultivars, pigmented with lycopene, have been discovered in Italy, Israel, Venezuela, Australia, China, South Africa, Brazil, Argentina, and the United States.
The first were ‘Vaniglia Sanguigno’, an old Italian acidless orange, and ‘Sarah’, a pink-fleshed sport of ‘Shamouti’ described in 1944. A pink-fleshed navel orange discovered as a sport of ‘Washington’ navel in Venezuela, ‘Caracara’, was released in Florida in 1987, and has since become commercially important around the world.
In the past decade, more than two dozen new pink orange cultivars have been introduced, varying considerably in the degree of pigmentation of pulp, juice, and rind; variegation of foliage and fruit; presence or absence of seeds; intended use, for fresh markets, processing, and ornamental use; and harvest season.
The genetic mutations and biosynthetic pathways resulting in the accumulation of lycopene in pulp and other plant tissues have been elucidated, as well as the flavor profiles and potential health benefits of pink oranges.
But despite the scientific and horticultural importance of pink-fleshed oranges, no review of information about pink cultivars exists; to fill that gap, this work provides nomenclature (denominations, synonyms, and trademarks); origins (parentage, location and date of discovery, discoverer, affiliated institution or company); descriptions of the fruits; descriptions of the trees; uses and processing characteristics; commercialization; and intellectual property details.
The sources for this survey, which vary for each cultivar, include scientific articles, intellectual property documents, direct observation of the trees and fruits, and information provided by breeders, rights managers, and growers.
