synonyms Notonia wightii Wight & Arnott (1834), Glycine javanica auct. mult., non L. (1753), Glycine wightii (Wight & Arnott) Verdc. (1966).

Vernacular names Glycine (En). Brazil: soja perene. Thailand: thua peelenian soibean.

Origin and geographic distribution The natural distribution of glycine ranges from Africa to Asia. It occurs as far south as the wetter parts of southern Africa, in East Africa, Ethiopia, India and mainland Asia and Indonesia. It can currently be found in many humid tropical and subtropical regions of the world since its widespread introduction for use as forage.

Uses Glycine is used as a grazed pasture legume in Australia in the subtropical and tropical high-altitude regions, and for grazing and hay in Brazil. It is used in small areas of Papua New Guinea where it volunteers as a fallow crop in abandoned gardens and is used as a cover crop and for woody weed control in overgrazed pastures.

Properties Nitrogen concentrations ranging from 24.2% have been measured in the leaves, with DM digestibilities of between 5561%. Although oestrogenic substances are present, no toxicity problems have been recorded.

Ecology Glycine is a short-day plant. Optimum day/night temperatures for growth and seed production of glycine are in the range 2227/16C with a base temperature for growth of 13C, lower than for most tropical legumes. It has limited frost tolerance, but leaf damage occurs in all cultivars.|It is adapted to dry to humid (8001800 mm) subtropical or high altitude (up to 3000 m) tropical regions with relatively deep, well drained, usually basalt-derived soils, and prefers a pH above 6.0. It is not adapted to very wet or waterlogged conditions. It is not as drought tolerant as siratro (Macroptilium atropurpureum (DC.) Urban), but more so than centro (Centrosema pubescens Benth.).

Prospects In South-East Asia, glycine will be limited to deep, fertile and well-drained soils in tropical high-altitude areas. Such areas are limited and this species is unlikely to be widely used. Currently no selection, breeding or development studies are being carried out.
