The ecogeography and collection of grain, forage and pasture legumes in south-west Turkey

Abstract

A collecting mission took place in June and July 1996 to collect legume species from south-west Turkey and western Anatolia. Sites were chosen to maximise the diversity of legumes collected and detailed passport data were recorded at each site. A total of 96 sites were visited, and 1307 accessions collected. In total 23 genera were collected, of which the most frequently seen were Trifolium, Medicago and Vicia. Sites were found to be almost exclusively calcareous with a pH range of 7 to 10, and varied from sea level to 1750m. Many of the Trifolium species are of economic importance for southern Australia and have been shown to display characters such as a high productivity (T. michelianum) and waterlogging tolerance (T. resupinatum and T. tomentosum). The Medicago species were found to prefer well-drained habitats in open areas. Many of these species can tolerate heavy grazing. The two main forage legume genera collected were Lathyrus and Vicia. Both of these occurred on the higher pH soils and were most frequently collected from the lower altitudes. Four species of grain legume were found, Cicer arietinum, Lens culinaris, Pisum sativum and Vicia faba. The material collected during this mission is important in the drive to preserve the legume genetic diversity of Turkey, the species' centre of diversity, for utilisation both within and outside of Turkey.
