Precise methods are required to assess the “substantial
equivalence” (Table 1) of transgenic and conventionally
bred berries.14 The methods available for assessing
berry TAC,15–17 combined with polyphenol concentrations
and other nutritional and quality parameters
(sugars, total acidity, and fruit color) are seen as appropriate
tools to develop a fast and reliable program for
screening large breeding populations, for the identification
of new cultivars with improved nutritional quality, as
well as optimized yields under changing climatic and
cultivation conditions,18,19 and as a first step in assessing
“substantial equivalence” in transgenic plants produced
for other aims.
