Challa has a long experience in the professional
improvement of gladioli. After graduating at the
Wageningen University she worked on the whitefly
resistance in cucumbers at the IVT. After that she
worked a number of years for a company that improved
roses, followed by the improvement of Crocosmia, small
flower gladioli and finally large flower gladioli. A

cross-breeding of resistance to Fusarium oxysporum.
