Abstract
The present investigations were conducted at the Vegetable Research Farm and Biochemistry Laboratory
of Department
of Vegetable Science, Punjab Agricultural University, Ludhiana during 2008-09 to 2010-11 with twenty two, eleven and four hybrids
obtained from public and private sectors and grown under polyhouse conditions during these years and evaluated for yield and
quality traits. From the study of three years, it was concluded that the hybrid HS-18 performed better than other hybrids for economic
traits and this hybrid can be exploited commercially for cultivation under polyhouse conditions.

Introduction
Tomato (
Solanum lycopersicum
L
.
) is a popular
vegetable all over the world because of its high
nutritive value and versatile uses (Kamran et al., 2011;
Regassa et al., 2012). Tomato is a warm season
crop and requires a relatively long growing season and
moderately high temperature (20-28°C).It ensures that the
optimum fruit setting is at night temperature and
the optimum range is 15°-20°C. It is a rich source of
vitamin A and C and eaten as salad and cooked as
vegetable. Tomato is the second largest crop among
the processed vegetables. It is processed into various
forms such as juice, ketchup, paste puree etc (Takeoka
et al., 2001). Mayeaux et al. (2006) indicated the
potential health benefits of a diet rich in tomatoes and
tomato products. Lycopene, the pigment that is
responsible for the characteristic deep red colour of
ripe tomatoes and their products plays an important
role in human health and epidemiological studies have
shown it to reduce the risk of chronic diseases.
Lycopene is a major carotenoid without provitamin A
activity and is considered responsible for their
beneficial effects (Gerster, 1997; Rao and Agarwal,
1999). In Punjab, winter planted crop is most
successful one and gives a very high yield, but
distributed over a small time span of less than
two month. During peak harvesting season there is
glut in the market and there price crash, while during
rest part of the year it is in short supply and the price
rises beyond the reach of common man. Recently,
to overcome these environmental conditions and
pesticide residue problem protected cultivation
of vegetables, particularly polyhouse cultivation
of tomato, brinjal and capsicum has been
recommended by Punjab Agricultural University,
Ludhiana. Polyhouse cultivation of tomato offers
distinct advantages of earliness, higher productivity and
quality particularly pesticide residue free produce,
besides higher returns to growers. Under protected
environment the natural environment is modified
to the suitable conditions for optimum plant
growth which ultimately helps in the production
of quality tomatoes suitable for exports and
domestic consumption (Singh and Sirohi, 2006).
Occurrence of frost coupled with low temperature
during the month of December and January cause
death of tomato plant when grown in open field
conditions, but under protected environment, the
yield loss can minimized. However, the technology
for producing quality tomato fruits have been
standardized yet there is no information available
regarding performance of different hybrids under
polyhouse. The following experiment was planned
with the objective of evaluating indeterminate hybrids of
tomato in respect of yield and quality under protected
conditions.
1 Results and Discussion
The present investigation was carried out to ascertain
the information on performance of different tomato
