Transcript RLO -Root Stock selction in Grape

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
Rootstocks for different Conditions

Rootstock varieties
 Dogridge
 Salt Creek (Ramsey)
 110 Richter
 St. George
 1616-C
 1613-C
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.
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 September–October 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.
1. Vertical cut on Rootstock
2. Tide Plastic Stripe
3. After Grafting
5. 2 Month After Grafting
4. 15 days After 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
