The development of Talish clover (Tri folium tumens Steven ex M . Bieb .) as a potential new perennial pasture legume for low rainfall temperate environments
Trifolium tumens is a long‐lived, deep rooting perennial legume from the T ri f olium Sect.Vesicaria Crantz., with a natural distribution across Turkey, Caucasus and Iran (Zohary and Heller 1984 ).There are a number of described varieties of T.tumens (Zohary and Heller 1970), but no commercial cultivars.T.tumens can be found growing across a broad range of environments.On a germplasm collecting mission to Azerbaijan by the senior author in 2004, T.tumens was collected from altitudes ranging from 11 to 1591metres above sea level,in soils ranging from pH(1 :5 H2 O) 5.0 to 9.0 and rainfall zones of 300 to 1300mm per annum.In Azerbaijan T.tumens can be found growing in heavily grazed lowland pastures with companion species Medicago sativ a subsp.caerulea, T ri f olium f ragi f erum, Lotus corniculatus, T ri f olim di f f usum, T ri f olium lap p aceum,Medicago polymorpha and Chicorum intybus or in lightly grazed alpine meadows with companion species Lolium perenne,Dactylis glomerata,T ri f olium repens,T ri f olium p ratense and T ri f olium ambiguum.In many areas it was seen as an important legume component in the pasture and at low rainfall sites ( ＜ 400 mm) was the only perennial T ri f olium species present.
