WA’s biggest private grain grower John Nicoletti, who is based in Merredin, said wheat growing technology and innovation had peaked for his farm business and is only capable of wielding minimal influence on its future viability. Speaking to Rural Press about the future of wheat growing for Australian farmers, Mr Nicoletti said genetically modified wheat research might bring some future benefits in the years ahead. But any new varieties, possibly with frost tolerance or drought resistance, are at least seven to 10 years away from commercialisation.
