Abstract

In the evaluation of vegetable cultivars, the high average yield in the competition assays associated to quality factors are utilized as criteria to recommend cultivars. In the present work we evaluated the lettuce cultivars Frisella, Deisy, Tender Green, Lollo Bionda, Itapuã 401, Marisa, Verônica, Banchu New Red Fire and Hortência under the climatic conditions of the region of Manaus, under protected and conventional cultivation. The evaluated characteristics were: total and commercial weight, plant diameter and height. The lettuce cultivars Marisa, Itapuã 401 and Hortência presented higher production in both environments adding Verônica with best production under conventional cultivation.
