Grower member Geoffery Phillpot, who told growers at Elsoms' brassica conference last week that the firm was created in the 1980s to breed cauliflower varieties more suited to the Kentish climate, said: "Of our seven members, five have ceased cauliflower production.
"Difficult decisions faced us - especially the need to keep up with the breeding techniques. We did not have the resources we needed so we had to forge a link with a French firm. It is impressed with how wide our gene bank is.
"Existing varieties will be maintained and will be available from the existing suppliers - and new varieties will emerge. You will see this in three or four years' time."
The agreement, he said, was made in May last year. Phillpot added: "In this difficult environment we have had no option but to seek some help from outside. We think it will be beneficial to both parties."
He pointed out that in the company's earlier days, Trinity Growers members used to travel as far afield as Japan to find varieties for the breeding programme.
