Genetic Technology (Precision Breeding) Bill

Debate between Lord Winston and Lord Taylor of Holbeach

Report stage
Wednesday 25th January 2023 Lords Chamber

[Lord Roborough (Con)]

As a non-scientist, I am not sure that I have a good answer to that. I would rely on the vets.

[Lord Taylor of Holbeach (Con)]

I think my noble friend is quite right: we will depend on increasing productivity and will be able to do that only by breeding. The whole point of the Bill is selective breeding; actually, it is precision breeding. The noble Lord may well have this nightmare that we are releasing something ghastly into the world; I do not believe that is true at all. It is done because of objectives in the breeding programme, which is precise. This is just the sort of thing that I do—and I declare my interest as a horticulturalist, as the House well knows—when we are breeding bulbs and daffodils. But this is more serious; this is not about domestic gardening but is about feeding the world and making it possible for the diversity that exists in gene stock to be harnessed for greater productivity.

[Lord Winston (Lab)]

I do not want to argue with the noble Lord about this too much but, actually, I have to say that there is good evidence. For example, with gene editing and the operation called i-GONAD where you can change embryos, most of those animals look perfectly normal and would pass without their gene being changed, but it turns out, of course, that they do not actually fulfil the requirements that you eventually have for the gene. That is one of the problems. That is a serious issue because you change other genes; not as a result of editing them, but by having those other genes edited. That is a big problem.
