Title: Black Table Grape 'Heukboseok'
Authors: K.S. Park, H.K. Yun and H.S. Suh
Abstract:
‘Heukboseok’, a tetraploid (4X) grape,
resulted from the cross between ‘Beniizu’
(4X, Vitis sp.) and ‘Kyoho’ (4X, Vitis sp.) at
the National Horticultural Research Institute
(NHRI), RDA, Korea in 1992, and was preliminarily
selected in 1998. Regional adaptability
tests were conducted in seven sites
from 1999-2003 under the name of ‘Wonkyo
RA-14’. It was finally selected in 2003 due
to its large and high quality berries with excellent
skin color.
Although most tetraploid
cultivars have a berry shattering problem,
‘Heukboseok’ showed a low incidence of
berry shattering, resulting in a good berry set
compared with ‘Kyoho’. ‘Heukboseok’ has
a mean budburst on 16 April, flowers on 1
June, and fruit matures on 9 September (almost
10 days earlier than ‘Kyoho’) at Suwon,
Korea.
The mean berry weight of 10.6 g
and mean soluble solids of 18.4˚Brix are
similar to ‘Kyoho’. The skin color is blackblue
with abundant bloom and flesh firmness
is soft and juicy.
It is recommended that it
be pruned to 6 to 12-node canes, 2 to 4 nodes
shorter than ‘Kyoho’ during winter because
it is not as vigorous. ‘Heukboseok’ may be
used as a substitute for ‘Kyoho’ in grape cultivation
in Korea, due to its large sized berries
with high quality and several characteristics
for facilitating vineyard management such
as excellent skin color, good cold hardiness,
good disease resistance, and good fruiting.
