Mexican geophytes I. The genus Polianthes

Members of the genus Polianthes L. are bulbous ornamentals in the Agavaceae, includes 15 species three varieties and a two cultivars native to Mexico. Polianthes tuberosa L. (Tuberose) is the only species cultivated as an ornamental cut flower in tropical and subtropical areas. The cultivation of tuberose occupies a prime position in the floriculture industry in countries such as Mexico, China, India, New Zealand and Taiwan. The Flower colour of all known cultivars of P. tuberosa is white; however, attempts have been made to introduce colors from related species. Besides its use as an ornamental, it is cultivated for use in manufacturing: as a source of fragrant essences in perfumery, to extract polysaccharides and glycosides; in addition P. geminiflora (Llave & Lexarza) Rose is utilized as a source of saponins for soap. The main diseases in this crop are caused by virus and it is affected by a coleoptera (Scyphophorus acupunctatus) whose larva feeds on the bulbs. In this review we will cover the uses, distribution, species, of the genus and the current state of tuberose breeding as a further reference for tuberose breeding programmes
