Plant introduction involves introducing plants from their native environment to a new environment. It can involve new crop varieties, wild relatives of crops, or entirely new crop species. Primary introduction releases varieties well-suited to the new environment without alterations, while secondary introduction subjects introduced varieties to selection or hybridization to develop improved varieties. The main plant introduction agency in India is the National Bureau of Plant Genetic Resources, which coordinates other agencies and maintains a gene bank. It has several substations for acclimatizing introduced plant materials in different climatic zones across India. Other agencies involved in plant introduction are the Forest Research Institute and Botanical Survey of India.

3.  PLANT INTRODUTION
 Plant introduction is a process of introducing plants (a
genotype or a group of genotypes) from their own
environment to a new environment.
 The process of introduction may involve new varieties
of crop or the wild relatives of crop species or totally a
new crop species for the area.

4. INTRODUCTION MAY BE
CLASSIFIED INTO TWO
CATEGORIES
 Primary Introduction:
 When the introduced variety is well suited to new
environment then it is released for commercial
cultivation without any alteration of genotype. For
example, dwarf wheat varieties like ‘Sonora-64’, ‘Lerma
rojo’ and dwarf rice varieties like ‘Taichung Native 1’,
‘IR-8’ are the examples of primary introduction.

5.  Secondary Introduction:
 When the introduced variety is subjected to Selection
or used in hybridization programme with local
varieties to get the improved varieties with some new
characters introduced called secondary introduction.
For example, the varieties like ‘Kalyan Sona’ and
‘Sonalika’ of wheat have been selected from material
introduced from CIMMYT, Mexico.

6.  4.AGENCIES OF PLANT INTRODUCTION IN
INDIA:
 The central plant introduction agency in India is
National Bureau of Plant Genetic Resources (NBPGR),
which has its headquarters at New Delhi, but has
substations for testing the plant materials. NBPGR has
the gene bank for long term storage and future use; it
helps to assess the introduced plant material,
coordinates the work of other agencies and imparts
training in plant collection, introduction and
maintenance in India.

7. ARE:
 Shimla:
 It represents the temperate zone of approx. 2300m
above sea level, place for germplasm collection in
northern hills, station for acclimatization of material
introduced from temperate zone and high altitude.

8.  Jodhpur:
 Exclusively meant for exploring and acclimatizing
plant material for arid zone, this is under Central Arid
Zone Research Institute

9.  Amravati:
 This substation carries out acclimatization and
multiplication of introduced material for central zone
of India.
 KanyaKumari:
 It represents the tropical zone situated at South India.

10.  Shillong:
 This centre has been created for collection of
germplasm from North-East India.
 Other agencies engaged for this purpose are:
 Forest Research Institute, Dehradun:
 The plant introduction organization set up at the
institute looks after introduction, acclimatization,
conservation and testing of forest trees.

11.  Botanical Survey of India:
This body is meant for introduction of medicinal
plants and also plants for botanical importance.
Other Sources:
Different Central Research Institutes as well as
Agricultural Universities play the role for collection,
introduction and maintenance of germplasm of crop
plants.
