For more than 20 years Cyprus barrel medic has been the mainstay of pastures grown on the medium to heavy red clay loamss of Western Australia'slow rainfall wheatbelt. However, since the early1980s its resistance to aphids has declined followed by reduced productivitymand persistence.
Fortunately, a six year research program at Tenibdewa, near Mullewa, is on target to prove the superiority of Parabinga barrel medic and a mixture of Serena and Santiago burr medics. These varieties, which had not been widley tested in the region, generally out-perform Cyprus in all aspects because of their higher tolerance of aphids.
