ABSTRACT
In the city of La Plata (Argentina) and the surroundings, there are tomato
landraces, widely known as “tomate platense” and particularly prized because of their flavor. The objective was to
evaluate seven promissory lines of “tomate
platense” (TL) derived from
local varieties and a commercial hybrid (CH) considering yield, fruit
characters and their possible associations. Nine plants per treatment were
arranged in a randomized complete block design (r = 4). The following parameters were determined: diameter
(cm), height (cm), diameter/height (D/H) ratio, weight per
fruit (g), number of locules, the average number of fruits per plant, the
average weight of fruits per plant (kg/plant), the yield (ton/ha) and the survival
percentage. ANOVA, Tukey’s test and Pearson
correlation coefficient were applied. The TL showed greater (P ≤ 0.01) diameter, D/H ratio
and number of locules than CH. In all
materials, both diameter and height were associated (P ≤ 0.05) with the weight per fruit. Six of TL had greater (P ≤ 0.01) weight per fruit than HC. Respect to number of fruits per
plant, weight of fruits per plant
and yield, there were no significant differences among the
materials. The survival
for CH was lower (P ≤ 0.05) than that for TL. Although fruits with a smaller size and less
flattened have been selected, the lines show enough similarity in these
characters that identified their common origin. With the fruits smaller and more uniform, and having
no joined fruits, these lines may be of interest to be cultivated under
low-input system conditions and practical for low-income producers.
