04: Colour and flavor
- Green colour in grape is due to pigment
- Yellow pigment: Quercetin
- Red, blue and black colour pigment: Anthocyanine
- Flavour of grape is due to sugar, acid and Tannins.
05: Types of grape
According to use grape are as follows:
5.1: Table grapes

- Main table varieties are, Thomson seedless, Pusa seedless, Anab-e-Shahi, Beauty seedless, Bangalore blue, delite and perlette.
5.2: Rasin grape
- Grape that can be dried are included in this group.
- Varieties containing more that 20% sugar are used for rasin making.
- Both seed and seedless variety are used for making rasin.
- Seeded rasin making: Munnaka
- Rasin from seedless grape is known as kismis.
- Important cultivars are, Thompson seedless, black corianth, Muscat of Alexandria, Pusa seedless, Sultana
5.3: Wine grape
- Used for producing wine.
- Grape with high acid and low sugar content are suitable for table wine.
- Grape with high sugar content and low acid are used for desert wine/sweet wine.
- Glucose and fructose in grape are converted in to alcohol and CO2 by the activity of enzyme produced by wine yeast (Saccharomyces crevisiae)
- Important cultivar for wine grape are, White Riesling, Aligore, Chardonnay, Black champa , Matarao, Mission, and Ruby red.
5.4: Juice grape

- Presence of excess salt mainly sodium and calcium (Na and Ca) are not good for grapes.
- Electrical conductivity (EC) should be less than 4
- Exchangeable Na is >25%
- Hot and dry climate is ideal.
- Area with humidity and high rainfall are not suitable.
- Higher night temperature above 25 °C hamper colour development during ripening.
- Pink pigmentation develops in green grapes if the difference between day and night temperature are more than 20 °C.
- Temperature should not be more than 35 °C.
- Under high humidity berries are not ripened properly and there is high incidence of disease.

- Grape is mostly propagated by hard wood stem cutting.
- The diameter of the cutting should be 8-10 mm.
- Cutting is generally done in the month of October.
- For increasing the rooting of stem cutting it should be dipped in IBA solution 500 ppm for over night and 2000 ppm IBA for 10 second.
- The rooting media should have 30-40% well decomposed manure.
8.1: Propagation Method

8.1.2: Grafting and budding
- Grafting and budding are also common in grape vine.
- Bench grafting is widely used in grape.
- Whip grafting is done in late winter or early spring season.
‘T’ budding and chip budding are also used.
- The trench or pits should be 1 m wide and 75 cm deep.

13: Training and pruning in grape
Different system of training.
- Head system
- Knifing sytem
- Telephone system
- ‘V’ shaped system
- Exponded Y system
- Bower system
- Productive potential of vine is better in bower system.
- In India bower system of training is most commonly adopted.
- It is expensive.
- Cost- benefit ratio- 1: 2.09.
- It is not suitable for mechanization of cultural operation.
- Head, knifing and telephone sytem-Produce low yield, Result sun burn of berries.
- ‘V’ and ‘Y’ system -They are better in case of sunburn, Yield is low.
In North India pruning is done during Dec-Jan.
In M.H, A.P and Karnataka pruning is done twice (April and Oct.)
15: Manure and fertilizer
- Mg. deficiency occurs as a result of heavy dose of ‘K’.
- Grape require more potassium and nitrogen
- N is requiring for shoot growth during fruiting season.
- K is requiring after bud differentiation for shoot maturity and for increasing the size of fruit bud.
Cattle manure: 25-50 tones /ha
Oil cake: 5 tones/ha
Organic mixture: 1200 kg/ha
For reducing Mg deficiency 100-200 kg Magnesium sulphate (MgSo4) /ha/ year are applied.
- Grape is a shallow feeder crop.
- Light and frequency of watering are suitable for grape.
- High water requirement during berry dryer hot weather growth.
- Least water requirement during fruit bud formation.
- During ripening irrigation should be reduced of at least 1 month before harvesting to improve the quality and fasten the ripening.
- Moisture stress during ripening increase berry drop.
- Best method of irrigation is drip irrigation.
- Economic life of grape is 7-8 years.
Quality of irrigation water
- Electrical conductivity: < 1mm mos/cm.
- Chloride content: 4 me/lit
- SAR (Sodium absorption ratio): less than <8.
- Residual sodium carbonate: less than < 1.25 me/lit.
- Baron: less than < 1 mg/kg.
- Harvest vine when fully riped
- In seeded grapes seed become dark brown when they are fully ripe.
- In seedless variety berry colour developed fully.
- Grape should be harvested during cool time of day.
- For local market grapes are packed in a bamboo strip basket.
- For distant market wooden cardboard box are used.
- Grape is packed in ventilated cardboard box using sulphur dioxide releasing pods which is known as “grape guard” in packing material to check the post harvest diseases, during transport and storage.
- Storage is done at 0 to 10 °C temperature and 90-95 % RH in cold storage.
- Yield potential of grape is highest in India.
- Anab-e-sahi: 92 tones/ha.
- Thomson seedless:48 tones/ha.
- Average yield of seedless variety: 20 tones/ha.
20: Post harvest technology
- Rasin are only processed product in India
- Around 30 % of seedless grapes are dried to produce tones of rasin.
- Golden Bleached Raisin are produce by shade drying.
21: Physiological disorder
- Found in Bangalora blue
- It occurs due to in adequate leaf area and non availability of reserves for developing bunch.
- Control: cluster thining, gridling.
- Use of growth regulator: Ethapon 250 ppm are sued.
Post harvest berry drop
- Common in Anab-e-Shahi, and Cheema-Shahibi.
- Control: NAA 50 ppm before harvesting.
Flower bud and flower drop
- Common in north India.
- Control: steam gridling, 10 days before full bloom.
Pink berry formation
- Common in Thomson seedless, Tas-a -ganesh.
- Pink colour turns red colour and berry become soft and watery.
- Storage life reduce.
- Control’ spray of 0.2% ascorbic acid and 0.25% sodium-diethyl-dithio carbonate at 15 days interval.
