The introduction of orange flesh tomato in Nigeria climatic conditions through
characterization is the best way to understand its adaptability and fight against the lack of
ß-carotene in the landraces and improved varieties currently cultivated in the country. This study
was aimed to evaluate7 tomato varieties comprised of 4orange-fleshed tomato imported from
New Zealand and 3 local varieties for their morphological, agronomic and chemical composition
and fruit quality characters. Phenotyping was used to assess the morphological and agronomic
traits and while biochemical assays was used for fruit quality characters. The four orange fleshed
tomato varieties were indeterminate and the 3 local varieties were determinate. There were
significant variability and differences in plant height (54.93 cm to 72.23 cm), leaf number (14 to
24), leaf length (24.10 cm to 28.53 cm), length width (15.13 cm to 16.93 cm), internode length
(2.41 cm to 3.29 cm), root collar (3.46 cm to 4.53 cm), days to 1% flowering (20 to 23), days to
maturity (34 to 42), number of clusters per plant (5 to 10), fruits per cluster (4 to 6), fruit weight
(72.64 g to 488.58 g), fruit length (27 mm to54.89 mm), fruit diameter (23.67 mm to 28 mm),
transverse fruit section (1 mm to 3 mm), moisture content (92.30 to 95.33%), protein (0.15 to
1.02%), fat (0.15 to 1.02%), fibre (0.92 to 2.37%) and carbohydrate (1.86 to 6.41%). At the time
the local varieties senesced they showed higher yields than the introduced varieties, but as
indeterminate they were better than the local ones because they continued fruiting after the local
ones died off. Flesh color of pericarps and ripened fruit color ranged from orange to red while
fruit shape varied from highly rounded to cylindrical (long oblong). Fruit size showed variation
from small to moderate size.
