3. Introduction
Among the vegetables maximum attempts
have been made to improve this crop because
of its short duration, easy cultivation and large
number of seeds per fruit and this has made it
a. n ideal crop for many research workers.
An exclusive Tomato Genetics Co-operative
located in University of California, USA,
andpublished
maintains
genetic information on crop
a large number of collections which
have already been thoroughly catalogued.
4. Origin and distribution
Tomato has its origin in Peru, Equador and Bolivia on
the basis of availability of numerous wild and
cultivated relatives of the tomato in this area.
From its centre of origin, the tomato first moved
to Mexico for domestication and cultivation

16.29 tonns / ha. The leading producing states are
UP, Karnataka, Maharashtra, Gujrat, Punjab, Haryana
and Bihar.
5. Uses
•Tomato is also rich in medicinal value.
•The pulp and juice are digestible, mild aperients, a promoter
of gastric secretion and blood purifier.
•It is reported to have antiseptic properties against intestinal
infestations.
•In the present days, it is gaining more medicinal importance
because of the antioxidant property of ascorbic acid and
lycopene content.
•It is also an important source of -carotene and valued for
their colour and flavour.
•Thus, today it is one of the important raw materials for
multimillion food industries. Tomatoes are also called as “Poor
man’s apple”.
•Tomato is consumed either fresh, cooked or processed into
various products like juice, ketchup, sauce, puree, whole
canned fruit and is the main constituent of ‘pizzas’.

8. L. cerassiformae is the immediate proginator
and L.hirsutum is ultimate proginator.
Interspecific crosses between L. esculentum
and L. pimpinellifolium are easily made.
Embryo abortion may occur between L.
esculentum x L. peruvianum. However, this can
be overcome through embryo rescue technique.
Chromosome Number: True diploid, 2n= 24.
All species of Lycopersicon have 2n=24.

been grown before.

20. 2. PURE LINE SELECTION: A pure line is
progeny of single homozygous plant of self
pollinated species. Therefore, all the plants in
a pure line have the same genotype.

25. 8. Heterosis Breeding:
Though, tomato a self pollinated crop has a tremendous
potential for heterosis breeding. The commercial exploitation
of hybrid vigour in tomato has received greater importance on
account of several advantages of hybrids over pure line
varieties with response to marketable
resistance
fruit yield and its
component traits as well as to biotic and abiotic
stresses. That is why large number of commercial hybrids have
been developed in the country in this crop. With increasing
popularity of F1 hybrids in tomato, it is imperative to obtain
such hybrids which have excellent qualities
with resistance to diseases.
