  • Pre 1900s Negative or Positive mass selection
  • Post 1900s selections based on measured
    parameters
  • Late 1920s Clonal Selection trials began in
    Germany by Sartorius (Riesling)
  • Based on greatest potential yield increases
  • Late 1960s ENTAV-INRA begin clonal selection
    based on quality

3
History Clonal Selection In Australia
  • 1788 - Vines arrive with first fleet (South
    Africa Argentina)
  • 1817 Pinot Noir Meunier introduced by
    Governor McArthur
  • 1832 570 varieties introduced by Busby from
    premier grape growing regions of Europe
  • 1836 vines from Busby collection planted in SA

4
History of Clonal Selection In Australia
  • 1958 - Harry Tulloch collects fruit weights from
    individual vines
  • 1962 - Selected the top 6 and bottom 2 yielding
    clones based on 5 yr average
  • Referred to as H1 to H6 L1, L2
  • Virus screening using woody indexing
  • 1966 - 1st replicated clonal trial at Loxton

5
Yalumbas Clonal Selection Program
  • Program established in late 1990s
  • Selection based on wine quality
  • Known health status
  • Improve genetic diversity
  • Three parts
  • Importation from international selection
    programmes and distinguished vineyards
  • Yalumba Selections
  • Assessment of commercial clones rootstocks

6
The ENTAV/ INRA trademark specifies origin,
authenticity, sanitary quality and genetic value
of clonal selectionThe clones selected and
produced over the last 40 years by ENTAV/ INRA
constitutes over 90 of the current planting in
France ENTAV/ INRA have produced over 15,000
individual clones for assessment. Some of the
more well known clones originally selected and
established by ENTAV/ INRA include Pinot Noir 777
and Chardonnay 76 95

Yalumbas Clonal Selection Program

    Pinot Noir Chardonnay
  • Viognier Sauvignon Blanc Yalumba imports
    commercial clones

Clonal Selection Program Shiraz
  • Oldest Shiraz vines in the world
  • Project Aims to
  • Identify clonal variation between Eden Valley
    Barossa Valley Shiraz clones
  • Preserve genetic diversity
  • Improve overall wine quality
  • Candidate vineyards used in Yalumbas Icon Shiraz
    - Octavius
  • Vineyards range in age from 40 to 127yrs

9
Clonal Selection Program Shiraz
  • 1999 - 5 Candidate vines selected per vineyard
  • Tested for viral status using PCR
  • Fruit maturity, colour chemical analysis
  • After 2 yrs a single mother vine is selected
  • Cuttings collected propagated

10
Clonal Selection Program Shiraz
  • 2001 Replicated trial planted in commercial
    vineyard
  • Includes 13 old vine Shiraz clones
  • 7 x Barossa Valley vineyards
  • 6 x Eden Valley vineyards
  • 4 x commercial Shiraz clones
