Nine new disease resistant and high yielding "super fodder" crops have delivered more than $45 million in benefits to the Australian farm fodder industry.

The new varieties of lucerne, stylo, cowpea and oats were developed by the GRDC supported Cooperative Research Centre for Tropical Plant Protection (CRC TPP) research.

CRC TPP chief executive officer John Irwin said the new varieties would boost a growing seed and fodder export business targeting a US$10 billion export trade in Asia and had helped open export markets for Australian seed in Argentina, Saudi Arabia and Tunisia.

"At home the new varieties are expected to boost Australian dryland lucerne production by 10 per cent and irrigated lucerne by up to 30 per cent over the next 5-10 years, as well as being resistant to a wide range of root and leaf diseases," he said.
