'The threat of climate change brings with it an enormous disruption to the food and plants we depend on for food.'
. To learn more, I talked to Dr. Varshney, a professor at Australia’s Murdoch University who is part of a team working to create more resilient tropical fruits.Tropical fruits such as bananas, passionfruit, custard apples, papaya. The threat of climate change brings with it an enormous disruption to the food and plants we depend on for food. We are responsible for creating resilient crop varieties that can thrive amidst changing climatic conditions.
Traditional methods of developing resilient crop varieties are time-consuming, taking up to 10-15 years, which is not feasible given the urgency. The Australian fruit industry has already seen large-scale losses of young fruit trees or seasons where the heat is destroying fruits such as strawberries. As winters get warmer, we could see an obvious decline in apple, pear, cherry and nut yields. That is because these trees are usually dormant during cold periods.
Also, we are working on accurately forecasting climate-resilient traits against the predicted climate changes in our fruit-growing regions. From this, we can map the usefulness of these traits by statistically testing the correlation between different genes and plant traits. We believe that there will be a lot of indirect benefits because the breeders will use this platform to develop varieties that the growers need. So, the growers will guide the development of improved varieties, which will have higher drought tolerance, higher heat tolerance, and appropriate fruit size and taste as per the need of consumers.
