HC Deb 11 February 1977 vol 925 c870W
Mr. Richard Wainwright

asked the Minister of Agriculture, Fisheries and Food what evidence he has that the price of seed potato is causing more potato producers to use once-grown seed.

Mr. Bishop

Most producers of ware potatoes use a proportion of once-grown seed. I have no evidence that more producers intend to do so this season. There has, indeed, been a lively demand for certified seed of varieties which showed good resistance to drought and leaf roll last season.
