Abstract

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 during the years 2010 and 2011. 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  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 the fruit number per plant a decrease tendency of fruit weight has been remarked. Carmina had 170cm plant height and an 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 number of fruits  per plant (r=0.49), number of flowers  per inflorescence (r=0.48) were positive and the correlation coefficient for the fruit yield with the days to the first fruit maturity (r=-0.46) was negative . A delay of fruit maturity conducted to a decrease in the number of fruits (r=-0.78**), an increase in fruit weight (r=0.80) and pH (r=0.71). Therefore, varieties with more fruits had low pH (r=-0.75**). Regarding the 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 tomato varieties was classified in four different groups:soft, relatively stiff, stiff and very stiff. Blossom-end rot in the cultivars BSS282, Tima and TO4 were less than in other varieties. Sunscald was seen in the first harvesting. Low percentage of fruit cracking was observed in more varieties and in Selb-Jino, Cal-J-N, TO2, Carmina and Early Urbana had more amounts.
