In order to evaluate of
twenty-five tomato cultivars for selecting superior
genotype(s), an experiment was carried out in Kahriz station
of agricultural research center of west Azerbaijan province
at two years of 2010-11. Experimental design was Randomized
Complete Blocks with three replications. Combined analysis
of variance showed that for agronomical and quality related
traits were significant differences. Selb-Jino, TO2,
Early-Urbana, Carmina, Cal-J-N and Falat-Shof with more than
10.5kg/m2 had the highest fruit yield. Selb-Jino had more
than 260 fruit at per plant, 7.8 flowers at per
inflorescence, less than 112 days to first fruit maturity
and pH 3.8 at two years. With increasing fruit number at per
plant decreased fruit weight. Carmina had 170cm plant height
and indeterminate growth. TO4, Chase, Selb-Jino and Carmina
with more than 5.2% had the most total soluble solid in
fruit. Correlation coefficients of fruit yield with fruit
number at per plant (r=0.49*), number of flower in per
inflorescence (r=0.48*) were positive and with days to first
fruit maturity (r=-0.46*) was negative significant
differences. With delaying fruit maturity decreased fruit
number (r=-0.78**), increased fruit weight (r=0.80**) and pH
(r=0.71**). Therefore, varieties with more fruits had low pH
(r=-0.75**). From the point of fruit shape Carmina, Nina,
Selb-Jno and BSS282 were quite uniform. To4, TO2 and Chase
had the most fruit color and Carmia and Seb-Jino were the
lowest values. Fruit firmness of cultivars was in four
groups of soft, relatively stiff, stiff and very stiff.
Blossom-end rot in cultivars of BSS282, Tima and TO4 were
less than other varieties. Sunscald was seen in first
harvesting. Low percentage of fruit cracking was observed in
more varieties and in Selb-Jino, Cal-J, TO2, Carmina and
Early Urbana had more amounts.
