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
bunch-muscadine hybrids.


BUNCH GRAPES NEARING POSSIBLE RELEASE

Seedless Table Grapes (4):

Fla. BN5-101 A dark red seedless with 2.4 g berries and 136 g clusters;
very good texture and excellent flavor, 23% sugars; edible skin; 63.2
flesh/seed remnant ratio; relatively free of fruit rot (Fla. BD6-47 x Ark.
1105 1982).

Fla. BN6-101 A light green seedless with 2.2 g berries and 131 g
clusters; edible skin; good texture and very good flavor; 18% sugars; 38.5
flesh/seed remnant ratio (Fla. DC1-39 x Lakemont 1982).

Fla. BN12-101 A light red seedless with 1.8 g berries and 92 g
clusters; edible skin; good texture and very good flavor; 19% sugars; 31.4
flesh/seed remnant ratio (Daytona x Lakemont 1982).

Orlando Seedless (for comparison) A light green seedless with 1.4 g

Fla. CN1-90 A light green, productive grape, self-fertile, with dual
purpose for both a table grape and white wine; resistant to PD and fruit
rotting; vigorous vines; 3.2 g berries and 215 g clusters; very good texture
and flavor; resistant to cracking and fruit rot; 33 flesh/seed ratio (Suwannee
x Verdelet 1982).

Fla. CAll-17 A light green, vigorous, productive grape, self-fertile;
3.6 g berries and 120 g clusters; very good texture and flavor; 20% sugars;

Fla. BN6-85 A light green, seeded table grape with 5 g berries and 350
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
slipskin type may be useful for white wine as well as for dooryard (Fla.
E9-48 x Ark. 1105 1972).

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 -
1978).

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
1983).

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
productivity; 2.3 g berries and 136 g clusters; texture good and flavor very
good; pH 3.2; solids of juice 19.0; held pigment well in shelf test (Blanc Du
Bois x Lakemont 1982).

Fla. DN18-47 A light green, seeded selection with very good vigor and
productivity; 2.2 g berries and 233 g clusters; texture good and flavor very
good; pH 3.2; solids of juice 18.6; holds juice color at room temperature
without browning for 8 days or more. Bunches moderately compact and rot
resistant (Fla. BD5-67 x Fla. F9-68 1983).

Bunch Grape Rootstocks (3):

Fla. CD9-81 An excellent bench grafter that is nematode resistant, PD
resistant, and vigorous in nursery and as a replant in the vineyard; roots
readily from hardwood cuttings (Dog Ridge x Tampa 1978).

Fla. 13C-12 Another super bench grafter and rooter from cuttings with
good vigor, scion unions, and yield boost of scions grafted on it (Haines City
x Alden 1961).

Fla. 13B-5 A sister to Fla. 13C-12 with excellent ratings for bench
grafts, great vigor, strong unions, promoting the growth and yield of scions
grafted on it (Haines City x Alden 1961).


MUSCADINE GRAPES NEARING POSSIBLE RELEASE

Table Grape (Fresh Market) (2):

Fla. CA9-48 A self-fertile, black grape with slightly oval berries; dry
scar; uniformly ripening berries that shake readily into the catch frame at
one picking; 7.5 g berries, stable pigment, very good fresh fruit
acceptability in taste panels (Fry x Southland 1976).

Fla. AA7-44 A self-fertile bronze grape with 11 g berries and 71 g
clusters; texture crisp and very good and flavor excellent; edible skin;
sugars 23%; flesh/seed ratio of 40; truly a breakthrough on muscadines that
can be eaten like a plum; vine vigor only moderate (Triumph x Fla. AD3-42 -
1983).














Red Wine/Juice Type (1):

Fla. AA10-9 A self-fertile black grape with 6 g berries and 54 g
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
application the day before harvest (Southland x Dixie 1979).

White Wine/Juice Type (1):

Fla. AA10-29 A self-fertile bronze grape, very productive, with very
good juice quality which holds on shelf over 10 days with no browning; pH 3.3;
sugars of squeezed juice 16.2; 5 g berries and 72 g clusters; dry scar (Summit

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
flavor good to very good; pH 3.9; sugars of juice 16.2; vigorous and extremely
productive; leaves like muscadine (not lobed); rot-resistant even when fruit
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].
