2.Member States shall determine the amount to be included in the reference amount of each farmer on the basis of objective and non-discriminatory criteria such as:
the amount of market support received, directly or indirectly, by the farmer in respect of fruit and vegetables, ware potatoes and nurseries;
the area used to produce fruit and vegetables, ware potatoes and nurseries;
the amount of fruit and vegetables produced, ware potatoes and nurseries,
in respect of a representative period which could be different for each product, of one or more marketing years starting from the marketing year ending in 2001 and, in the case of the new Member States, from the marketing year ending in 2004, up to the marketing year ending in 2007.
The application of the criteria in this point may be varied between different fruit and vegetable products, ware potatoes and nurseries, if duly justified on an objective basis. On the same basis, Member States may decide not to determine the amounts to be included in the reference amount and the applicable hectares under this point before the end of a transitional three-year period ending on 31 December 2010.
