This document provides information on tomato breeding in 3 paragraphs: 1) Tomato originated in Peru and Ecuador and was domesticated in Mexico. It is now widely grown in India, with the top producing states being UP, Karnataka, Maharashtra, Gujarat, Punjab, Haryana and Bihar. Breeding objectives include increasing yield, improving fruit quality, and developing resistance to diseases and stresses. 2) Common tomato breeding methods include introduction, pure line selection, single seed descent, single plant selection, mass selection, pedigree selection, backcrossing, heterosis breeding, and interspecific hybridization using wild relatives as donors of traits. 3) Emerging biotechnologies for tomato breeding include

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’.

6. TAXONOMY
Family- Solanceae
Linnaeus called it Solanum lycopersicon.
Miller: Lycopersicon esculentum
Now restored as Solanum lycopersicon. Lykos=
Wolf, persicon= peach.

fruited edible species with carotenoid
pigmentation, annual and self compatible.

pigmentation and self
incompatible.
E.g. L. hirsutum, L. peruvianum, L.
cheesmani, L.chilense

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.

environments where they have not
been grown before.
Ex. Sioux from USA, Marglobe from USA.

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.

as a description of the ancestors of an
individual and it generally goes back to some
past.distant

would describe the parents, grand-
parents, great grand parents and so on.
 It is useful by finding out if two individuals
are related by descent, have a common parent
in their ancestors and they have some genes in
common.
Eg: Arka Meghali of tomato PS (F8) of Arka
Vikas x IHR 554
Pusa Ruby selection from Improved
Meeruti x Sioux

24. 7. Back Cross Method: A cross between a
hybrid (F1 or segregation) and one of its
parents is known as back cross. Hybrid
subsequentand the progenies in the
generation are repeatedly back crossed to one
of the parents.
 Followed when character is governed by
one/few genes.
 For Early blight, Nematode and Bacterial

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.

of ripening and in ripe fruit it is one of the major cell-wall-
bound proteins.) Eg. FLAVR SAVR Variety available in
market.
(ii) Viral Coat Protein – Introduced gene which can
synthesize the protein which coats the virus material. Eg.
Avinash-1 and Avinash-2 varieties.

herbicide. Means variety should not be affected but weeds
should be cleared.
