• In drought prone areas, grapes are propagated by softwood

grafting / wedge grafting.

• Grape varieties like Thompson seedless, Tas-A-Ganesh, Sonaka

etc. has good production potential however yield has reduced

due to high soil salinity, drought and nematode attack.

• To over come this problem, wedge grafting in grape is practiced.

Root stock becomes ready to graft within 6-8 months after

planting and graft union formed in 30-45 days.

Introduction

• Dogridge, Ramsey (Salt creek),

1613-C and 110-R grow vigorously

under adverse soil and climatic

conditions.

• Among all these rootstocks,

Dogridge gives higher yield in

drought, salinity and nematode

prone areas.

Selection of Rootstock

Rootstock Planting

• Root stock stick of 20 cm long with 7- 8 leaves are planted in the field during February - March when temperatures are above 15o C and favourable for shoot and root growth.

• Root stock Plantation should be install with drip irrigation system and follow timely plant protection measures.

Selection of Scion Sticks

• Scion stick of desired variety with good yield potential and compatibility with root stock should be selected.

• Pencil thickness scion sticks of 5-6 cm length are treated with 0.1 % Carbendazim fungicide for 2 to 3 Hrs.

• Rootstock accumulate sufficient amount of food material and attains sufficient thickness within 7-8 months up to August.

• Favourable climatic conditions i.e. 300 to 350 C temperature and 80 % relative humidity for successful grafting are available from August to September.

• Give a “V” shaped notch (vertical cut) of 2-3 cm long on root stock and prepare wedge shaped cut on scion stick.

• Insert scion stick in the notch of rootstock properly and tie the graft union with 1 cm polythene tape.

• Regular irrigation should be given to grafted plant to avoid mortality of grafted plants.

• Irrigate the field in early morning and evening to maintain essential humidity and temperature.
