Introduction Pineapple (Ananas comosus) is one of the commercial fruit crops of India and its cultivation is the age-old practice in North Eastern Hill Region of India. The beauty and virtue of this Golden Queen have been extolled by many poets all over the Globe. Pineapple has all qualities required for being an ideal fruit crop for North Eastern India. The name Ananas, which later became the generic name, is derived from Tupi Indian name Nana. Pineapple is a unique fruit for its beauty of appearance, delicate fragrance and excellent flavour.

COMPOSITION AND USES Pineapple is considered as one of the most important tropical fruits. It is an important part of people particularly in south, east and North Eastern India. Pineapple fruit is rich source of sugar, vitamins and minerals. Pineapple is a good source of vitamin A and vitamin C and is fairly rich in vitamin B1 and B2. It contains enzyme bromelin and several odorous lactones have been found in Pineapple. The fruit contains moisture 85.0%, sugar 13%, protein0.6%, and mineral matter 0.05%.

The presence of proteolytic enzymes like bromelain in pineapple juice was demonstrated in 1891 as stated in LotzWinter. The highest concentration of bromelain is found in ripe pineapple fruit pulp and in the stems. Bromelain is commonly used in food production, in pharmaceutical industries and in diagnostic laboratories. After juice extraction pineapple fruit also possess a valuable ament of waste. Several by products are also prepared by waste e.g. alcohol, calcium citrate, citric acid and vinegar. Preparation of manosidase oxalic acid and pineapple gum and flavours is also possible. The pineapple fruit is used for preparing candy. The leaves yield 2-3% of strenge white silky fibrous, 38-90 cm length, which is used for making a fine fabric called pina cloth.

Constraints of Pineapple production Rainfed production system and erratic precipitation. Predominance of queen and Kew on farms. Lack of techniques among the growers. Peoples perception regarding pineapple cultivation. Poor organic matter & low moisture containing soils. Free grazing of animals especially during dry period. Poor communication for marketing during glut. Processing industry problem.

Smooth CayenneSmooth Cayenne pineapple originated before 1820 and was the type indigenous Venezuelans cultivated. The Spanish call it Cayena Lisa. Since then, this type became a leading pineapple in several countries. Modern cultivars that arose from breeding or selection of natural mutations of the Smooth Cayenne include Hilo, St. Michael, Giant Kew, Perolera, Charlotte Rothschild, Bumanguesa, Monet Lirio, Esmeralda, Typhone and Palin. These cultivars are grown throughout the world. Some are more widespread in various regions based on disease resistance, flavor or harvest scheduling.

Red SpanishRed Spanish pineapple is commonly grown as a commercial cultivar in the West Indies, Mexico and Venezuela as well as in Florida. Breeders crossed Red Spanish and Smooth Cayenne pineapples to create modern cultivars that are grouped in the Red Spanish class. Cabezona, Valera, Valera Amarilla, Valera Roja, Castilla, Cumanesa, Morada and Monte Oscuro are names of cultivars in this class.

QueenThe Queen or "common rough" pineapple is more compact in size and more tolerant of cold. Cultivars in the Queen class are still grown worldwide. Names of cultivars are Natal Queen, James Queen, Egyptian Queen, MacGregor, Alexandria, Kallara Local, Ripley and Calcutta.

AbacaxiAbacaxi pineapples are often regarded as the most fragrant and delicious of all. They bruise easily and don't make good commercial plants for canning, but are ideal for fresh markets. Today, Abacaxi types are numerous in Brazil, the Bahamas and South Florida. Sugarloaf, Black Jamaica, Eleuthera, English, Brecheche, Sugar Slice, Caicara, Chocona, Congo Red, Santa Marta, Criolla and Panare are names of pineapple cultivars derived from the original Abacaxi pineapple slection.

CULTIVARS A large number of varieties are grown in different parts of India. Cayenne group: Smooth Cayenne, Hilo, Kew Giant Kew and Charlotte Rothschild Queen group: Common queen, Mauritius, Ripley queen, Alexandra and Mac Gregor. Spanish group: Red Spanish, Singapore and Masmerah. Indigenous Group: Jaldhup, Lakhat, Baruipur Local and Haricharanvita

Cultivars Kew Plants are vigorous; leaves have short sector of spines at the tip and margins; fruits weigh about 1.5- 2.5 kg; eyes are broad and shallow making it more suitable for canning;Dr. JAI PRAKASH, Scientist (Horticulture)

Queen Most popular cultivar of Tripura. Plants- dwarf and compact; leaves- short, spiny along the margins; fruits weigh about 0.8 to 1.3 kg; peduncle-short, fruitlets or eyes are small, deep set; fruits although less juicier than the Cayenne group are less fibrous; TSS13 to 19 Brix and acidity 0.6 to 0.8%.

Mauritius Fruits medium sized and are of 2 types- yellow and red. Yellow types- Oblong, fibrous and medium sweet. Red types- Oblong, less fibrous and sweeter than the yellow types. Leaves-yellowish green, spiny throughout the margin and the crown is also spiny in both types.

It is a selection from a cross of Kew x Ripley Queen and developed from Kerala Agriculture University, Trichur. The leaves are short stiff, spiny along the margins, and thickly covered with a whitish bloom on both surfaces. Frits are similar to queen and suitable for table purpose. It ripes 10days late compare to queen. Fruit weight 0.8-1.1kg. Peduncle is short, fruit lets or eyes are small, prominent, deep set. The total soluble solids content varies from 16 to 180 brix and acidity between 0.5 and 0.6%.

Amritha

PQM-1 Fruits medium sized and suitable for table & canning purpose, fruit weight 0.91.4kg and late maturity. Orange colour, Oblong, fibrous and medium sweet. Leaves-reddish green, spiny throughout the margin and the crown is also spiny, TSS 14-17.4brix

MD-2 (PRI Hybrid 73-114) A unique hybrid develped from Pineapple Research Institute Hawai in the 1990-95. The PRI hybrid 73-114 is a sibling of hybrid 73-50 and the parents were PRI hybrids 58-1184x59-443. The hybrid composition is Smooth Cayenne17, Smooth Guatemala6, Pemambuco4, Ruby (Spanish Clone) and Queen 1. The marketing right belongs to Delmonte Gold group of companies.

MD-2 is a hybrid that originated in the breeding programme of the nowdefunct Pineapple Research Institute in Hawaii, which conducted research on behalf of Del Monte, Maui Land & Pineapple Company, and Dole.

CO-2A new plant variety of the Bromeliaceae, or pineapple, family, Ananas comosus, has been developed as an interspecific cross between Pineapple Research Institute hybrid clone 58-1184 and Pineapple Research Institute (PRI) hybrid clone 59-443, and has been named hybrid CO-2. This hybrid clone generally resembles the parent varieties, but is distinguished therefrom in that this plant produces a sweeter, more viamin C rich fruit, which is low in parasitic fruit diseases, and tolerant or resistant to the physiological disorder called internal browning. This plant has more uniform yellow color, good fruit appearance after refrigerated storage, and produces acceptable crop yields of saleable fresh pineapple

Propagation Pineapple is commercially propagated by suckers in India. However, it can also be propagated by slips and crowns but fruiting will be after two year of planting Stem pieces can be also used. Tissue culture: axillary and terminal buds from crown.
