Background: Tomato is considered as one of the important and commercial
products in Bushehr province, which has cultivars with different functional and
quantitative and qualitative characteristics. The final product production is the result
of genetic and environmental characteristics. Meanwhile, the presence of tomato leaf
miner (Tuta absoluta) causes irreparable damage to the amount of final production,
and the resistance of different cultivars cultivated in Bushehr province to this pest is
less studied.
Aim: Therefore, the present research was conducted to find the best commercial
tomato variety in terms of different quantitative, qualitative characteristics and
resistance to tomato leaf miner (Tuta absoluta).
Methodology: This research was done as two separate experiments with 5
treatments including Commodore, Badroud, Brenta, Brivio and 8320 tomato varieties.
In the first experiment, cultivation of different cultivars was done in the form of a
randomized complete block design in 3 replications. In the second experiment, in
order to produce the Tuta absoluta population was raised one generation of the pest
on each variety. Infected leaves were studied under microscope. The duration of
growth and development of males, females, individuals who died before reaching
puberty, and the daily reproduction of females were analysis based and growth
parameters were calculated on the age and life stage-specific bisexual life table theory
of Chi and Liu (1985) and the method described by Chi (1988).
Results: The results of analysis of variance showed that between different tomato
cultivars were significantly different in shoot fresh weight, stem diameter, leaf area,
number of clusters, plant yield, number of days to flowering, carotenoids, potassium
and fruit fresh weight (P≤0.01) and the amount of chlorophyll a, b and total
chlorophyll, phosphorus, calcium, the number of glandular trichomes, fruit diameter
and TSS (P≤0.05), but no statistical difference was observed between
