supply only products he has cultivated himself,

In the 1927-1928 catalogue, however, he is already
able to write proudly:

Custom selections
Even before 1927, Rijk Zwaan had been using a
number of test plots to study seed selection.
Whereas in the past the words ‘our own cultivation’
in catalogues was a type of quality assurance, the
term ‘selection R.Z.’ appears more and more often,
meaning that the seed is not just grown in-house
but also selected by Rijk Zwaan himself.
