This document summarizes information about biodiversity in mango plants. It begins by defining biodiversity and explaining why it is important. It then provides details about the botanical classification of mango plants, their origin in Southeast Asia, centers of diversity in India, important cultivars that have been developed, and objectives and methods for mango breeding programs. The goal of such programs is to develop new mango varieties with traits like dwarf trees, early and regular bearing, high quality fruits, disease resistance, and suitability for transport and processing.
2. What is Biodiversity?
• Biodiversity refers to the variety and variability among living
organism and eco-system complexes in which they occur.
• The whole word BIODIVERSITY generally therefore means:
VARIETY OF LIFE.
Why biodiversity important?
• Organisms are dependent to each other for survive.
• Each species of vegetation and each creature has a place on the earth
and plays a vital role in the circle of life.
• Food, shelter, wood, medicines and drugs are come from the
different plants on this earth.
• Greater species diversity ensures natural sustainability for all life
forms.
3. Mango

Chromosome number: 2n = 2x = 40
Origin:- Indo-burma
4. Botanical Classification:-
Kingdom : Plantae
Class : Mangoliopsida
Phylum : Mangoliophyta

5. INTRODUCTION:-
Mango is 'King of Fruits', in India. Mango fruit is utilized at all
stages of its development. It is also a rich source of vitamin A and
some other vital nutrients. The raw/ unripe fruits, because of their
acidic taste, are used for preparing pickle, chutney, drinks and
amchur.
The ripe fruits besides being consumed as table purpose are also
processed for preparing juice, nectar, squash, jam, cereal flakes,
mango leather and toffee. The fruits are also preserved as slices
and canned in syrup.
From the nutritional point of view the mango is rich source of
vitamin 'A' (4880 IU) almost as rich as butter. Also it has fair
amount of vitamin 'C' The carotene pigments, B carotene, increase
with ripening, whereas Vitamin 'C' had a sharp fall on ripening.
6. Origin, Distribution and History
• Mango is Native to South East Asia (Indo-Berma) specially
India.
• The name Mangifera is given by "Botinus" first time in 1658.
• Indo-Burma region is believed to be the primary centre of
mango.
• The name Mangifera indica is given by Linnaeus in 1753.
• Mango is one of the choicest fruits of India, grown over an
area of 1.23 million hectares in the country.
• Mango occupies the prime position in India and mango is
acclaimed as ‘King of fruits’.
• In India Uttar Pradesh is the leading mango producing state
followed by A.P.
7. AREA AND PRODUCTION
Mango occupies on an area of 1.17 million hectares with a total
annual production of 9.64 million metric tons contributing 42.64%
of total area under fruit crops, and 40% of the total production of
the fruits in India. It ranks third after banana and citrus in respect
of world fruit production and acreage. The state of U.P. is the
leading state in mango cultivation (0.493 million hectares
contributing 44% of total area under this crop) followed by Andhra
Pradesh (14.5%) and Bihar (13.2%). The present area of mango
crop under cultivation in Maharashtra is 35400 ha with an annual
production of 194700 tonnes. India has a major share 70% in
world production of mango of 13.44 million metric tones.
8. Centers of Mango Diversity and Distribution in India
1. Humid Tropical region-Manipur, Tripura, Mizoram and
S. Assam
2. Chota Nagpur Plateau-Trijunction of Orissa, Bihar and
Madhya Pradesh
3. Santal Paraganas in Bihar
4. South Madhya Pradesh adjoining Orissa and Andhra
Pradesh
5. Dhar Plateau of Madhya Pradesh adjoining Gujarat and
Maharashtra
6. Humid Tropical South Peninsular India
7. Andaman and Nicobar Islands

10. Germplasm resources
• India is the home of mango germplasm where more than
thousand varieties are existing.
• Central Institute for Subtropical Horticulture, (CISH) Lucknow
has the largest collection of mango (633 accessions in the national
repository) and they have greater genetic variability with respect
to fruit shape, skin colour, stone size, period and time of maturity,
pulp thickness, colour, bearing habit, yield and quality parameters
(Anon., 2002).
• Further, IIHR,Bangalore, IARI, Pusa, New Delhi, Sabour (Bihar),
Fruit Research station Sangareddy (Andhra Pradesh) etc. are also
maintaining the germplasm of mango.
• Almost all the commercial cultivars of mango are related to a
single species Mangifera indica.
11. • The Mangifera indica germplasm is divided into two
groups.
• 1. Seedling races
• 2. Horticultural races
• Seedling races are wild and cultivated types, which are
most common in Tropical Asia and almost all
commercial cultivars of mango are from this type.
• Horticultural races:- these are vegetatively propagating
types. These include both Mono and Polyembryonic
types.
12. Wild Species
• Mangifera pajang :- Largest Fruit, Easily peeled
• M. similis:- Free stone Mango Species
• M. magnifica - Free from fiber
• M. laurina - Resistance to anthracnose
• M. odorata :- Highest TSS
• M. altissima - Resistance to leaf hopper
• M. rufocostat - Off season bearing
• M. indica: commonly cultivated species
• M. pentandra :- Good polliniser

23. Problems in mango breeding
• Seedling plants take 5-10 years for bearing i.e. long juvenile phase.
• Presence of single seed in a fruit.
• Heterozygosity and cross pollination makes it difficult to predict the
quality of hybrid fruits.
• Complex nature of panicle and flower.
• Excessive fruit drop.
• Large area of land is required for raising hybrid seedlings.
• Lack of knowledge on inheritance pattern.
• Lack of pre-selection procedure for isolation of superior hybrid seedlings.
• Problem of polyembryony which makes identification of hybrids difficult.
