17:28 The Secretary of State for Environment, Food and Rural Affairs (George Eustice)

Precision breeding techniques can improve crop resistance to diseases, reduce the need for pesticides, increase crop yields, improve resistance to climate change, promote drought resistance and reduce the need for fertilisers.

With food security high on the agenda, we also have the ability to develop wheat that is more resilient to climate change, helping successfully to grow a crop that 2.5 billion people are dependent on globally. Researchers at the John Innes Centre in Norwich have used gene editing techniques to identify a key gene in wheat that can be used to introduce traits such as heat resilience, while maintaining high yields.

The hon. Lady asks whether I can be confident that this will not undermine the environment, and I can. Indeed, I am confident that it will lead to a reduction in the use of pesticides, which is a key objective that she will share with Conservative Members. It could also lead to a reduction in the use of synthetic fertilisers—currently the primary contributor to greenhouse gas emissions from the agricultural sector.

While I have put on a lot of weight since the mid-1990s, science has also massively moved on. In response to the intervention by the hon. Member for Brighton, Pavilion (Caroline Lucas), this is a bit like comparing a 1997 diesel car with modern zero-emissions vehicles. Yes, they both have wheels, go along in a straight line and are called cars, but the two things are completely different. The British public were right to be cautious at the time, but let us explain why this is different. We now know the genome sequences of other target species and plants, and we have exact tools that are effectively like clever genetic snippers that will go along a genome and only cut in the exact place. There is confidence and science behind that point. We then insert something that, as my hon. Friend the Member for Penrith and The Border (Dr Hudson) highlighted, comes from the same species. If we have wheat that does not taste nice but is good at growing in dry conditions, why can we not give it that dry condition gene, so that it tastes nice and is nutritious and can help feed the third world? There are scientists chomping at the bit to have a go at that—I really cannot wait.

The hon. Lady is making a lot of points about how this is, of course, a devolved area, but does she therefore disagree with the president of NFU Scotland, Martin Kennedy, when he says that precision breeding techniques such as gene editing, led by scientific expertise available in Scotland, have considerable potential to deliver benefits for food, nutrition, agriculture, biodiversity and climate change?

In broad terms, I support the idea of encouraging a science-based approach to technologies such as genetic editing for precision breeding. In general terms, I accept that such methods will be helpful in the fight against climate change and excessive antibiotic use, among other things, and that they have the potential to reduce the need for pesticides in farming. I welcome that the Advisory Committee on Releases to the Environment and the European Food Safety Authority have advised that no more risk is attached to precision-bred foods than to those from traditional breeding methods.
