NEW PEAR VARIETIES IN HUNGARY, SYSTEM AND TIME REQUIREMENTS FOR PUBLIC CULTIVATION

All new fruit varieties (either native as well as foreign) have to pass an official process of trial and evaluation (Value for Cultivation and Use – VCU), and an official process of virus testing or removal before it is available to nurseries or fruit growers in Hungary.
Using a large amount of data, time requirements of VCU have been examined for a number of varieties, which were introduced during a test period of ten years.
We have concluded that VCU testing takes between 3.5 and 4.7 years on average.
Varieties to set up, in a virus-free state, propagating stocks were found to take an additional 6.5 years on average.
In this way 10 to 11 years are required for new varieties to reach the fruit growers in the form of healthy propagating materials.
How can this time be shortened? First: the condition for drawing into public growing has to be just only the positive result of DUS (Distinctness, Uniformity and Stability) examination, which takes no more than 2 years, should serve as a basis of introduction a new variety into public growing.
Later the results of the following VCU examination should be simply recommendations.
Second: Production of pre-basic materials and DUS examination should be performed in parallel.
Third: Production of pre-basic and basic material should take place at the same time.
