“…Agave sisalana Perrine, which probably originated in Chiapas by hybridization between A. angustifolia and A. kewensis (Gentry, 1982), is named for the port of Sisal in Yucatán, Mexico from where it was originally exported during the 19th century for development of fiber production in India, Africa, and Brazil. The A. sisalana cultivar Hildana was widely used in East Africa, but a high yielding hybrid, H11648 (( A. amaniensis × A. angustifolia ) × A. amaniensis ), has replaced A. sisalana in Tanzania and other regions of Africa and is now the genotype cultivated in China (Bos and Lensing, 1973).…”
