Abstract:
'Mclntosh' is one of the leading cultivars
in the apple industry, and its
popularity with consumers indicates
that it will remain an important cultivar
in the future (21). Like many
widely grown cultivars, 'Mclntosh' has
given rise to a number of spur-type
mutants characterized by increased
spur production and reduced vegeta
tive growth.
These strains include
'Macspm; 'Morspur' (Raikes strain),
'Starkspur Mclntosh' (Gatzke strain),
'Starkspur UltraMac' (Dewar strain),
'Starkspur Compact Mac' (Wijcik
strain) (4), and 'Chick-A-Dee Mclntosh'
(19). The most distinct of these strains
is 'Mclntosh Wijcik' (Fig. 1), a colum
nar mutation discovered in Canada (4,
5). Stark Bro's Nurseries, Louisiana,
Mo, holds the U.S: plant patent for
'Mclntosh Wijcik,' marketing it as
'StarkspurR Compact Mac'TM.
'Mclntosh Wijcik' is characterized
by compaction of the internodes, re
duced lateral shoot growth, and in
creased spurriness (11). The fruit qual
ity and tree growth habit of this strain
were initially described as horticulturally
unsuitable (5), yet others have
since characterized fruit quality as sim
ilar to 'Mclntosh' with good color (16).
