Keeling said his father, who held the post for 25 years, steered the company through profound changes in the seed industry at a time when many UK companies closed down or were taken over.
"Anthony has worked hard to establish and maintain crucial supplier relationships with our European partners, based on our core values of professionalism, friendliness and honesty," said Roger.
"At the same time, he had the vision to embrace new technologies and techniques and make substantial investments in research, development and seed treatment that are now delivering results."
He added that the seed company was planning "significant expansion" over the coming year. "We are planning to take on more sales specialists as well as introducing a range of new varieties in field vegetable and agricultural crops, while also looking at investments to help us achieve our long-term strategies," he confirmed.
Anthony Keeling, who will remain chairman of Elsoms' holding company, is now deputy chairman. The Keeling family has been involved in the business since the 1940s.
