    INTRODUCTION

    BANANA -Adams FIG / Tree of wisdom / Kalpataru / Apple of

    paradise.

    Modern bananas and plantains originated in the South East

    Asian and Western pacific regions where their inedible, seed-

    bearing, diploid ancestors can still be found in the natural forest

    vegetation.

    Over many years, various inedible diploid subspecies ofMusa

    acuminataColla crossed naturally resulting in the production of

    numerous intraspecific hybrids

    Some of these hybrids were parthenocarpic, female sterile andtriploid in genomic structure, and local inhabitants discovered that

    such plants had edible fruits and could be propagated be

    vegetatively by suckers.

    In this manner, the superior edible crosses of Musa acuminatewould

    have been selected, cultivated, propagated and distributed locally as

    a food crop.

    The edible triploid banana in Southeast Asia were further selected

    according to vigour, fruit size and adaptability, and were inferior.

    However, in certain areas various edible diploids of Musa

    acuminatawere also preserved over the years.

    Diploid and triploid selections of Musa acuminatawere taken by

    man to drier mansoon areas where another wild and seeded

    diploid, Musabalbisiana, was growing naturally.

    In these areas, interspecific hybridization occurred to produce

    diploid and triploid crosses of Musa acuminatax Musabalbisiana.

    The introduction of Musabalbisianagenes from the drier monsoon

    regions into Musa acuminata clones from the humid tropics of

    Southeast Asia conferred a measure of hardiness and drought

    tolerance into hybrids.

    In addition the Musa balbisiana genes, induced greater disease

    resistance, improved nutritional value, increased starchiness and

    provided hybrids suitable for cooking, as opposed to the pure

    Musa acuminata cultivars which are sweeter and more suited to

    dessert use.

    DISTRIBUTION OF BANANA

    Historical references to banana and plantain are many and varied.

    The earliest written reference to banana is in Sanskrit and dates

    back to around 500 BC.

    Edible bananas originated in the Indo-Malaysian region reaching to

    northern Australia. They were known only by hearsay in the

    Mediterranean region in the 3rd Century B.C., and are believed to

    have been first carried to Europe in the 10th Century A.D.

    Early in the 16th Century, Portuguese mariners transported the

    plant from the West African coast to South America.

    The types found in cultivation in the Pacific have been traced to

    eastern Indonesia from where they spread to the Marquesas and by

    stages to Hawaii.

    DESCRIPTION OF BANANA

    It is a giant herbaceous plant with an apparent trunk that bends

    without breaking

    The banana has an underground stem with adventitious roots. It

    is full of food for the plant. Alongside the main stem, it has other

    stems called suckers. These stems grow into banana plants. The

    banana plant produces its fruit and dies. Another sucker replaces

    it.

    Previous Next End

    The banana plant has large leaves closely rolled up

    one over the other. Together they look like a trunk, butthey form only an apparent trunk.

    Inside it there is a bud which producesleaves. After 7 or 8 months, when some 30

    leaves have grown, the bud produces

    flowers

    The flowers of the banana plant form a large

    spike It turns downward, to the soil and

    opens. It bears male and female flowers.

    The female flowers pressed closely

    together in the shape of hands

    The banana plant yields fruits.

    These fruits are long in shape,with yellow or green skin.

    The spike produces many

    bananas.

    The bananas on one spike are

    called a bunch.On this bunch, the bananas are

    clustered in several hands.

    The flesh of a bananais light in colour, sweet and soft. In the

    middle of the fruit you can see little black specks;these are the

    seeds,but they will not germinate

    IMPORTANCE

    Bananas and plantain are very importantfruit crops in the tropical world.

    They are grown largely by small holders

    and play a major role in food security and

    income generation for millions of the

    regionsrural poor worldwide.

    In terms of gross value of production,

    banana is the developing worlds fourth

    most important food crop after rice, wheat

    and maize and as a fruit, it ranks first.

    More than 100 million tonnes of bananas are produced every year

    in 120 countries in over 10 million hectares.

    Only about 13 per cent of the worldsbanana production is exported

    and 87 per cent is consumed where they are produced, indicating,

    that banana plays a vital role as source of food and income in

    developing countries.

    Production statistics in 2004 show that banana is an important crop

    in the three major regions namely Asia, Latin America and Africa.

    India topped the list with 16.55 metric tonnes whereas the

    Philippines with a total production of 5.41 metric tonnes came in 6 th

    after Uganda, Brazil, Ecuador and China.

    India with the production of 16 million tonnes of bananas annually,

    provides livelihood security to millions of people in production, trade

    and processing.

    The fruit contributes more than 2.8% to GDP of agriculture in Indiaand 31% of the total food production.

    However the efficiency of banana supply chain in the country is not

    even a patch on the Indian manufacturing supply chain, resulting

    into high wastages (30%), high retail to farm gate ratio (1.8) and

    high mark up percentage i.e. prices paid by the consumers (300%)

    one of the highest in the world.

    Banana are cultivated commercially under tropical and sub-

    tropical conditions in all the states of India except in those having

    extreme winters such as Himachal Pradesh and Jammu and

    Kashmir.

    In Tamil Nadu bananas are cultivated in about 88,100 ha and the

    total production is estimated at 44,06,000 tonnes. The

    productivity is very high in Maharashtra (58.58 t/ha) followed by

    Tamil Nadu (50 t/ha).

    Though, India is the leader in banana production, Indian export of

    fresh banana is meager and it was only 280 metric tonnes during

    the year 1998.

    NUTRITIONAL VALUE

    Banana is an important source of energy and the cheapest sourceof nutrients for the bulk of our population.

    In terms of nutritional value, the fruits are rich in carbohydrates,

    minerals and vitamins.

    It provides more balanced food than many other fruit crops.

    In terms of energy, bananas are even better compared to potatoes.

    Bananas and plantains are recognized as the fourth most important

    global food commodity after rice, wheat and milk.

    The fruit pulp of banana has rich and easily digestiblecarbohydrates apart from many vitamins like riboflavin, niacin

    and ascorbic acid and minerals such as calcium, magnesium,

    potassium, phosphorus and has several medicinal properties.

    It is hence considered as fruit for all ages of people from infants

    to aged.

    In certain parts of India, banana powder is used as baby food.

    It has several medicinal virtues too.

    The fruits, florets and pseudostem are also used for consumption

    after cooking.

    Its leaves are commonly used for serving food in homes, many

    hotels and restaurants.

    Bananas can be also processed to purees, powder, flour, chips,

    jam, jelly, wine, etc. attractive handicraft items like mats, carry

    bags, etc. can be also made from the banana fibre.

    Besides, the fibres can be also used for making paper pulp.
