Significant change in wheat production across the state of Victoria, Australia is predicted if the climate changes according to the Inter-governmental Panel on Climate Change (IPCC) scenarios. Most critical to the dry areas are scenarios of reduced rainfall. For the more arid zones sowing a faster maturing type (cv. Silverstar) on the 1 June resulted in the best outcome with some small gains and losses predicted. Sowing earlier or later resulted in yield losses of around 10 to 20%. In the wetter areas of southern Victoria, consistent gains in yield of around 10-20% should occur in all cultivar types (e.g. Silverstar, Chara or Mackellar), but only from later sowing times (July to August).
