Exclusivity ruled out The development of registered trademark varieties grown exclusively by selected growers worldwide is under way with apples such as Pink Lady, Superior seedless and Midnight Beauty grapes, Black Diamond plums, and Amber Crest peaches. But leading exponent Sun World International based in California will not succumb to multiples' requests to create exclusivity, David Marguleas, senior vice-president, marketing and corporate development, told the FPC annual conference. His justification is that the industry is far too large and it takes as long as 20 years to discover and commercially develop new types of deciduous fruit, which can also perform very differently according to specific microclimates. But he says the trend to protected varieties will have a profound effect by giving growers better control of prices as well as reducing overproduction. {{FRESH PRODUCE }}
