Silver is the result of selection from introduced land races, derivatives of Sava, selected and bred by Q.D.P.I. Silver performs best in areas with arable neutral-alkaline soil types requiring early to mid maturity. Silver has shown very good adaptation to a range of soil types including the heavy textured soils through to sandy loams soils above pH7.
Flowering in Silver occurs approximately 77 days after germination, approximately four days after Sava. Silver has hard seed levels slightly higher than Sava. Silver is relatively upright in its growth habit, which allows the variety to compete very effectively for light. The pods of snail medics are more vulnerable than those of barrel medics because of size, as sheep will graze pods of snail medics and can severely reduce seed reserves in the soil. Silver has shown distinct yield advantages over Sava, particularly in heavy textured soil.
