See: Sorghum bicolor. Fibre

Plant fibres give strength to stems. Some of them can be retted to provide bast fibres for the manufacture of coarse materials such as sacking, sails, and tarpaulins. The most important of these are flax (Linum usitatissimum), hemp (Cannabis sativa), Manila hemp, or abaca (Musa textilis), Sunn hemp (Crotalaria juncea), jute (Corchorus spp.), and sisal (Agave sisalana).

With the development of plastic fibres, the demand for natural bast fibres has decreased dramatically. These crops are now relatively unimportant. Flax, hemp, and sunn hemp are easy to breed, but Manila hemp and sisal are not recommended for amateur breeders . Note that cotton is a plant fibre, but it is not a bast fibre and it remains a very important crop.
