Grape is an important fruit crop in Maharashtra.

1
Introduction

• Grape is an important fruit crop in Maharashtra.
• Need constant attention for production of export
  quality grapes.
• Rootstock is stump which has well grown healthy
  root system.
• Grape Rootstocks are wild relatives plants of
  grapes.
• Plant part which grafted on the rootstock is
  called scion.

Need of Rootstock

• Rootstocks are Sturdy plants which resist insect,
  pest, disease, and nematode infestation
• Tolerant to draught, salinity with profuse and
  Sturdy root system
• Increases crop growth, vigor and yield,

Selection of Rootstock
Grape vines not grafted on rootstocks may suffer
from phylloxera disease. Proper rootstock and
cultivar must be selected before grafting.
Selection of rootstock is based on the following
criteria Soil Fertility and Productivity
Climatic Condition of Region Grape Variety to be
grown Purpose of Grape Growing-Table or Wine
Purpose Desired level of Quality and Yield of
Grape

Selection of Rootstock

• Selection of rootstock in Grape should be made
  for following traits.
• Vigorous Growth of Grape Vines
• Tolerance to Soil Salinity
• Tolerance to Drought Condition
• Resistance to Pest, Diseases and Nematodes

Dogridge

• Highly Resistant to Soil Salinity, Nematodes and
  Draught condition
• Vigorous in Growth and Moderately resistant to
  Phylloxera disease
• Rootstock Leaves are shining and medium to large
  in size
• Rootstock shows Zinc and Chloride deficiency in
  plant

Salt Creek (Ramsey)

• Resistance to Soil salinity, Nematodes and
  Draught conditions.
• Vigorous in growth of Graft/scion with profuse
  growth of Suckers.

110 Richter

• Resistant to Soil Salinity, Nematodes and Draught
  condition
• Recommended for table and wine varieties of
  Grape.
• Moderately vigorous in growth with increased
  fruitfulness
• Rootstock restricts uptake of sodium and chloride
  from soil

St. George

• Resistance to Nematodes and Draught conditions
• Vigorous in growth of scion and graft.

8
1616-C

• Resistance to soil salinity and Nematodes.
• Vigorous in growth with Increased fruitfulness,
  yield and life.

1613-C

• Highly resistant to soil salinity, nematodes and
  Medium resistant to Phylloxera disease
• Leaves are medium to large in size with stalk of
  leaves are red in colour

Propagation of Rootstock

• Rootstocks are propagated by hard wood stem
  cutting with 4-5 nodes.
• Cuttings Planted in plastic bags in
  SeptemberOctober are ready for planting in field
  in 1.5- 2 month

Planting of Rootstock

• Planting season in February-March with Spacing 6
  x 8 feet or 6 x9 feet
• Planting Trench size 1 m deep x 1 m wide and
  length according slope of land.

Grafting on Rootstock

• In situ grafting in grape is successfully carried
  out in September- October months.
• Select 2-3 healthy and vigorous vines and cut
  down remaining shoots on rootstock.
• Take re-cut on vine at 1.5-2 feet height on
  selected shoot of rootstock.
• Graft the scion on rootstock, tighten the union
  with plastic stripe and provide bamboo stick
  support after 15-20 days of grafting.

Care of Grafting

• Remove plastic stripe after 2 - 2.5 month after
  grafting.
• Select one healthy and vigorous graft and Re-cut
  at 4 feet height from ground.
• Allow two primary shoots to grow in opposite
  direction.
• On primary shoot , three laterals are kept on
  either side as secondary arm which are treated as
  fruiting shoot

Re-cutting of grafted vines 6-7 months after
grafting
