DECEMBER 1988 UPDATE ON UPCOMING GRAPE VARIETIES
by J. A. Mortensen & J. W. Harris
Since the last update on new grape breeding selections a number have been
discarded because of Pierce's disease susceptibility, excess fruit rotting,
lack of pigment stability for processing, decline in productivity or quality
since first selected, or other reasons. The purpose of this research report
is to summarize the selections that are currently under serious consideration
for possible release within the next 4-year period. All need to be further
tested except for Fla. CA9-48 muscadine, which we intend to recommend for
release in 1989 as a mechanically harvestable black muscadine. Described
below are 4 seedless table type bunch grapes, 4 seeded table type bunch
grapes, 3 red wine/juice bunch grapes, 3 white wine/juice bunch grapes, and 3
bunch grape rootstocks. Also described are 2 fresh market muscadines, one red
wine/juice type muscadine, one white wine/ juice type muscadine, and 2

g clusters; relatively free of rot; edible skin; very good texture and flavor;
21% sugars; 41 flesh/seed ratio (Fla. DC1-39 x Himrod 1982).
Fla. BD12-49 A light green, seeded grape with 5 g berries and 209 g
clusters; texture and flavor good, with 21% sugars; problems with anthracnose
may prevent its release; vine holds leaves into the fall; a table grape of

Red Wine/Juice Bunch Grapes (3):
Fla. CA4-72 A purple productive grape with very good vine vigor;
self-fertile; 1.7 g berries and 111 g clusters, with loose clusters; fair
texture and very good flavor; 19% sugars; good pigment stability;
rot-resistant fruit resists cracking during ripening (Fla. W716 x Suwannee -
Fla. DC1-56 A purple, productive female with remarkably beautiful juice
that holds at room temperature for days with no browning; 2.8 g berries and
180 g clusters; good texture and flavor; 19% sugars with good balance in acid
(Fla. W1521 x Aurelia 1976).
Fla. DN16-59 A purple, productive, self-fertile selection with good
pigments; pH 3.2; solids of juice 21.4%; 1.8 g berries and 168 g clusters;
texture fair and flavor good; relatively free of rot (Fla. BD5-67 x Fla. F9-68
White Wine/Juice Bunch Grapes (3):
Fla. CN2-100 A light green, seeded selection with good vigor,
productivity, and pigment stability for wines; 4 g berries and 158 g clusters;
slipskin; fair texture and good flavor; pH 3.2 and solids 16.4; juice held
perfectly clear for 10 days on shelf (Suwannee x Verdelet 1982).
Fla. CN10-62 A light green, seeded selection with good vigor and

good; pH 3.2; solids of juice 19.0; held pigment well in shelf test (Blanc Du

one picking; 7.5 g berries, stable pigment, very good fresh fruit
acceptability in taste panels (Fry x Southland 1976).

clusters; texture fair and flavor excellent; pH 4.1; sugars 18.0; vigorous and
extremely productive; rot resistant; does not shell; uniform ripening; about
45% dry scar, compared with 30% for 'Noble', so would benefit from ethephon

stable pigments; 7 g berries and 72 g clusters; very vigorous and productive;
fair texture and very good flavor; pH 3.9; sugars in squeezed juice 18.2;
could have multi-purpose use for table, juice, or wine but not fully dry scar
(47%) so may require cluster clipping or use of ethephon 24 hrs before harvest
(Summit x Fla. P9-15 1979).
Fla. DB6-4 A self-fertile black grape with 3 g berries and 100 g
clusters (larger than any pure muscadine); 93% dry scar; texture fair and

hangs overripe, juice pigment stable at room temperature 15 days, shakes with
a dry scar and satisfactorily uniform ripening for once over harvest [Fla.
H13-11 (V. munsoniana cv. 'Marsh' x 'Magoon') x 'Bonne Chance' (DRX60-40
open-pollinated two generations) 1976].
