> Really big things may come from Pixie, a very small grape recently
> released by the Agricultural Research Service (ARS).
> The seeded black fruit of this grape line is not meant for eating.
> Instead, the variety's novel traits make it ideal for genetics,
> genomics, breeding and other research that can lead to new breeding
> lines or cultivars that grape consumers will love.
> Pixie fits well into its classification as a dwarf variety.
> According to Peter Cousins--the geneticist in the ARS Grape
> Genetics Research Unit at Geneva, N.Y., who helped develop it--
> mature clusters of Pixie typically measure slightly less than four
> inches long. He said that a Pixie grapevine can be grown in a
> coffee cup and still produce some grapes.
> This characteristic reduces by about 50-fold the amount of space
> needed for grapevine experimentation, as Pixie vines can be grown
> in the greenhouse to maturity without ever needing to be planted in
> a vineyard.
> But what really makes the new grape line special is its ability to
> initiate fruit year round. In fact, according to Cousins, it's
> typical to observe flower buds, blooms, immature fruit, and ripe
> fruit--all on the same vine.
> While this trait would not be useful for the consumer-grape
> industry--grape producers prefer to pick their crop just once--it
> does accelerate research, allowing for year-round studies on
> flowers and berries at all stages of development.
> Cousins and University of California-Davis scientist David Tricoli
> developed Pixie by regenerating whole plants from embryogenic cells
> of the Pinot Meunier variety of grapes.
> The concept of developing such dwarf grape plants was first
> demonstrated and published by Australian scientists Paul K. Boss,
> Mark R. Thomas, K.G. M. Skene and Martin Barlass.
> Intellectual property protection will not be sought for Pixie,
> according to Cousins.
