Stirt . is a herbaceous perennial legume widely distributed in the Mediterranean Basinand Macaronesia . In the Canary Islands the species presents a larger diversity with ３ botanical varieties found in habitatsranging from the coastal semiarid areas on Lanzarote Island with an annual rainfall of １５０mm to ３００mm ( var . albomarginata)to the high elevation subhumid area of Tenerife with up to ５００ mm annual rainfall ( var . crassiuscula) ( Mendez et al . , １９９０) .The third var . bituminosa has a wider adaptation across the Canary Islands and is the only one present in other parts of theMediterranean basin . Var albomarginata ( Lancelot trefoil) and var crassiuscula ( Teide trefoil) have recently been accepted forintroduction by Biosecurity Australia and can now be evaluated as potential pasture species in Australia .Materials and methods In ２００６ /７ , the research with Lancelot trefoil commenced in Western Australia in ５ key areas : １ )Rhizobium matching and cross nodulation with Australian native legumes ; ２ ) determination of breeding system and developinghand‐crossing techniques ; ３) field evaluation at ５ sites with Mediterranean‐type climate receiving less than ４００ mm of annualrainfall and with contrasting soils ; ４ ) grazing tolerance and forage quality and ５ ) seed increase and flowering pattern studies .Results and discussion A root nodule bacterium isolated from Canary Islands soil , and probably of the genus Meso‐rhizobium hasbeen shown to effectively nodulate Lancelot trefoil . Cross‐inoculation trials with root nodule isolates from Australian Cullenspecies indicated no nodulation of Lancelot trefoil . The self‐pollinated breeding system of the plant ( Juan et al . , ２００４ ) wasconfirmed and a crossing technique was developed . The year ２００６ /７ was particularly dry , almost the driest on record in south‐western Australia and Lancelot trefoil not only persisted , but it grew well and was productive during summer . A noticeableattribute was its ability to retain green leaves during the dry period . This characteristic will allow strategic grazing by farmerswho value a source of green feed during the dry season . A pilot grazing experiment showed that sheep grazed the plants in thepresence of other palatable forages and recovery of Lancelot trefoil af ter grazing was excellent . Forage of this leafy legume haddigestibility values of ７０％ ‐７５％ and crude protein of １５％ ‐２０％ . These plants were able to compete with the common annualpasture species ( i .e . A rctotheca . calendula Levyns and T ri f olium subterraneum L .) without the aid of herbicides . Floweringpattern was monitored monthly and seeds of １５ available accessions were hand‐harvested during summer .Conclusions Lancelot trefoil is showing wide adaptation in the Mediterranean regions of Western Australia . Future research willbe focused on breeding this species and developing an agronomic management strategy for its use in the low‐rainfallMediterranean regions of Australia , particularly for areas where lucerne ( Medicago sativ a L .) is not well adapted .ReferencesMendez , P . , Fernandez , M . , Santos , A . , １９９０ .
