Our breeding objectives are creating bulbs suitable for large scale production.
It means, among others, we select on the next features:
- good growing capability
- disease non-susceptibility
- suitable for forcing in water culture
- low production costs
- harvest reliability
With the objective to prevent loss as a result of diseases, we put a lot of effort in the development of varieties which are non susceptible for the most important diseases in tulips.
- On preventing susceptibility for fusarium oxysporum, we select the most tolerant varieties. Within the available varieties and tulip species we select the most tolerant ones to use as a parent in our breeding program.
- On preventing susceptibility for Tulip Breaking Virus (TBV), we aim on making resistant varieties. In tulip species, resistance to Tulip Breaking Virus is available. Interspecific breeding with tulip species is a difficult and long process. Difficult because of the very poor seed setting in interspecific crossings. It’s a long process, because backcrossing is necessary, we can’t use all the features of the tulip species. A complicating factor is the sterility in the interspecific hybrids. Nevertheless, the last years we succeeded in making a lot of interspecific hybrids. In the now available interspecific hybrids we have almost all colors present. Within the coming next years we hope to introduce Tulip Breaking Virus resistant varieties suitable for forcing even in yellow and white.
We already introduced a lot of tulip varieties, mostly under Plant Breeding Rights. Partly under our own license agreement, partly in cooperation with others and partly under license from a third party.
