Feeding the booming world population of 10 billion people by 2057 is a task taken on by the UWA with assistance from researchers worldwide

Wheat is a major cereal crop that will need to have production increased dramatically to feed an accelerated population of 10 billion by 2057

The University of Western Australia’s Institute of Agriculture has collaborated with international researchers to develop a roadmap to fast-forward breeding for accelerated crop improvement and rapid delivery systems, which will lead to a more food-secure world.

A Perth-based workshop organised by The UWA Institute of Agriculture and the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), and attended by research institutions from Australia, India, Austria, China, Mexico and the United Kingdom discussed research into this issue recently.

The current world population of 7.8 billion is predicted to reach 10 billion by 2057.

Future access to affordable and healthy food will be challenging, with malnutrition already affecting one in three people worldwide.

The research recognised that global crop production systems need to expand their outputs sustainably to feed this rapidly growing human population.

The fast-forward breeding framework provided a strategy for integrating advanced technology in crop genome sequencing, phenotyping and systems biology, together with efficient trait mapping procedures and genomic prediction (including machine learning and artificial intelligence).

Adopting seed input supply systems and new production and harvesting technologies would generate increased incomes for farmers and deliver better products to consumers.

is seen as one of the most stable crops to produce and researchers believe they can help growers through breeding programs that will increase current yields and improve global food security

This would lead to establishing rapid delivery systems into global farming practices, which is required to achieve sustainable food security in the developing world.

The UWA Institute of Agriculture Director Hackett Professor Kadambot Siddique worked with ICRISAT Accelerated Crop Improvement Research Program Director and Adjunct Professor from UWA and Murdoch University Rajeev Varshney to develop the strategy and opinion papers.

“Realising desired productivity gains in the field is imperative for securing an adequate future food supply for 10 billion people,” Professor Siddique said.

“We need to establish and deploy rapid delivery systems to ensure farmers can access high quality seeds and appropriate agronomy packages.”

Professor Varshney said increasing adoption of machine learning algorithms would provide valuable data about the genetic basis and molecular mechanisms of crops.

“This improved understanding is crucial to develop varieties faster,” he said.

The fast-forward breeding framework demonstrated that emerging breeding approaches, such as optimal contribution selection (alone or in combination with genomic selection), would enhance the genetic base of breeding programs while accelerating genetic gains.

“Integrating speed breeding with new-age genomic breeding technologies could relieve the long-standing bottleneck of lengthy crop breeding cycles and contribute sustainable food security,” Professor Varshney said.
