Details of Comparative Trial
Location Merbein, Victoria
Descriptor Grapevine (Vitis) TG/50/8.
Period 2005-2007
Conditions Vines for comparative trial purposes were grown in pots
under shadehouse conditions. Ampelographic data were
collected from vines growing under vineyard conditions.
Trial Design ‘Merbein 5489’ was compared with 14 other rootstock
varieties or selections, viz. Borner (Vitis riparia x V. cinerea),
‘Freedom’ [a complex multi-species hybrid (V. labrusca, V.
riparia, V. vinifera) complex hybrid) x (V. rupestris x V.
candicans)], ‘41B’ (V. vinifera Cv. Chasselas x V.
berlandieri), ‘125AA Kober’ (V. berlandieri x V. riparia),
‘5C Teleki’ (V. berlandieri x V. riparia), ‘K48-38 Lider’ [V.
rupestris x V. candicans (aka Vitis champini) x V. vinifera Cv.
Sultanina], ‘K48-45 Lider’ [V. rupestris x V. candicans (aka
Vitis champini) x V. vinifera Cv. Sultanina], ‘K48-48 Lider’
[V. rupestris x V. candicans (aka Vitis champini) x V. vinifera
Cv. Sultanina], ‘Cosmos 10A’ (V. berlandieri x V. riparia),
‘Dogridge’ [V. rupestris x V. candicans (aka Vitis champini)],
CSIRO selections ‘Merbein 5512’ (V. berlandieri Ressequier
No. 1 x V. berlandieri Mazade), ‘Merbein 6262’ (V. cinerea
55 x V. cinerea 194-1), ‘M61-19’ (V. cinerea 55 x V. cinerea
194-1) and ‘M61-36’ (V. cinerea 55 x V. cinerea 194-1). The
trial included three other Vitis rootstock varieties for which
Part 1 PBR applications have been submitted. As a result, the
comparators for these other varieties were also included and
the data were analysed together. Vines were propagated from
dormant cuttings collected during winter 2005. They were
struck in a sand/perlite mix in a cold mist house over bottom
heat. Rooted cuttings were potted into a standard potting mix
and transferred to a shadehouse in 12l pots. The vines were
allowed to grow as single shoots by removing lateral shoots
as they developed. When shoots had grown to a length
exceeding 1m, they were pruned to two buds and the
youngest bud was allowed to develop. The vines were again
allowed to grow as single shoots by removing lateral buds as
they developed. When shoots had reached a length exceeding
1.5m, they were again pruned and leaves at nodes 5-10
retained for measurements to be recorded. There were 14
comparator varieties with 15 vines per variety. The trial was
laid out as a randomised block design with one replicate vine
