Researchers in John Hopkins University discover that some varieties of
broccoli have more sulforaphane than others. I want to know what
varieties are the best.

    Explaining better: 
    
    Broccoli is classified like Brassica Oleracea Italica
    
    The researchers of John Hopkins University quantify the  amount of 
    glucoraphanin ( 4-methylsulfinylbutyl) in  many cultivars(varieties)
    of broccoli and other "Brassicas"

    The name of this cultivars (Brassica Oleracea Italica) are: 

     Saga, DeCicco, Everest, Emerald City, Packman, Corvet, Dandy
Early, Emperor, Mariner, Green Comet, Green Valiant, Arcadia,
Calabrese Caravel, Chancellor, Citation, Cruiser, Early Purple
Sprouting Red Arrow, Eureka, Excelsior, Galleon, Ginga, Goliath, Green
Duke, Greenbelt, Italian Sprouting, HiSierra, Late Purple Sprouting,
Late Winter Sprouting White Star, Legend, Leprechaun, Marathon,
Mariner, Minaret (Romanesco), Paragon, Patriot, Premium Crop, Rapine
(Spring Raab), Rosalind, Salade (Fall Raab), Samurai, Shogun,
Sprinter, Sultan, Taiko, and Trixie, and Viking.

  I want to know the name(s) of  the cultivar they think is (are)the best.
  In other words: When Caudill Seed Company of Louisville, Kentucky sell
  broccoli sprouts , what is the name of the cultivar?

  I said Caudill because this is a Company which is autorized  to sell the
  cultivar they think is the best.  

  "All Brassica sprout facilities must purchase their seed from a
certified seed supplier. Brassica requires superior seed quality to
maintain its food safety standards, and only Caudill Seed Company of
Louisville, Kentucky has met the rigid standards for seed production
and storage. They directly supervise the growing and harvesting of the
specified seed and then ship them to a network of carefully selected
sprout growers located nationwide. These seed varieties were
identified by Johns Hopkins researchers to contain the highest level
of SGS? (sulforaphane glucosinolate), a naturally occurring plant
compound that supports antioxidant function. BroccoSprouts are the
only sprout guaranteed to contain 20 times the concentration of SGS as
mature, cooked broccoli. Caudill Seed has 250,000 square feet of
American Institute of Bakers (AIB)- and Food and Drug Administration
(FDA)-compliant food grade storage and cold storage for more than one
million pounds of seed."

WHAT CULTIVAR IS THE BEST IN GLUCORAPHANIN?
THAT IS THE QUESTION.

The original 1997 work out of Johns Hopkins that identified the high
level of activity in sprouts was based on the SAGA cultivar.

There's no way I know of, though, to trace this 1997 development
through to the actual commercialization steps.  SAGA may or may not be
in use at Caudill, but I suspect only they could tell you for certain.

Does that sort of information help at all?

This is the type of information I need, but , how you discover this
 information? Do you have links showing that information?

Yes,

I can provide a link to the article.  But is that what you want as an
answer to your question, or are you in need of additional information
as well?

I don't want to provide only half an answer!

Can I see the link? If this link proves that Saga is the cultivar
          with the most quantity in Glucoraphanin in the research of the
          John Hopkins University I will be satisfied.
          If this link is one of the links which Crabcakes send to me ,
          forget, because in none of this links I  saw the answer.

Broccoli sprouts: An exceptionally rich source of inducers of enzymes
that protect against chemical carcinogens


MATERIALS AND METHODS

Plant Source and Cultivation. Seeds not treated with pesticides were
obtained commercially. Sprouts were produced from seeds
surface-sterilized by a 1-min rinse in 70% ethanol, a 15-min exposure
to 1.3% sodium hypochlorite containing 0.001% Alconox detergent, and
exhaustive rinsing with sterile distilled water. The broccoli
(Brassica oleracea var. italica) cultivar used was SAGA, unless stated
otherwise...

Sorry Paf , you send me a link where they use Saga for a study.
    But they didn`t told in a single moment Saga is the best cultivar.
    For example in the following link in the study they show that Saga 
    is not the best cultivar column 13 and 14.
     http://www.brassica.com/pdf/US05968567.pdf
     Remenber what I said in the clarification: 
    "If this link proves that Saga is the cultivar
          with the most quantity in Glucoraphanin in the research of the
          John Hopkins University I will be satisfied."

I suspect the information you need may be out there, but I'm afraid I
can't justify the effort that would be involved to sort through the
many reports, patents, etc, especially since there's no assurance an
answer can be found.

I wish you luck in your quest, however.
