摘要
in the evaluation of vegetable varieties, the highest average yield in the competition assays combined with quality factors are used as criteria recommended for planting. the object of the present work was to evaluate five commercial sweet pepper hybrids protectively cultivated in climatic conditions of manaus. the experiment was carried out in an arc type vegetation house, measuring 50.4m in length and 7m in width and covered with 100 microns of plastic. the experimental design consisted of randomized blocks with four replications and plots of 20 plants. the following characteristics were evaluated: weight (fw) and number (fn) of fruits produced by each plant, average weight (faw), length (fl), diameter (fd) of fruits, and fl/fd (rld) relation. the data were submitted to analysis of variance and average comparison (tukey). although a significant effect of the total fruit weight was not verified, statistically significant differences occurred in the fruit traits. the magali r and nathalie hybrids, traditionally cultivated in protected environments in the amazon, presented more elongated shaped fruits, which are preferred by consumers. the fruits of safari r hybrids, though less elongated than the magali r and nathalie, presented a major weight average that satisfies the local market exigency, making it a good alternative to the diversification of cultivated hybrids.
