Resumo:  Lettuce is one of the main vegetable species used in organic production. However, studies and research in the organic area are scarce. This study aimed to evaluate the yield and quality of seeds of lettuce genotypes produced in two consecutive years under an organic management system. Two plantations were installed under open field conditions corresponding to autumn/winter in 2016 and 2017. Ten lettuce genotypes were evaluated in four replications using a biofertilizer made from swine manure in the management and manual harvesting of seeds. Evaluations consisted of seed yield (in kg.ha−1), physical test (1000-seed weight), and germination and vigor test (first germination count, germination rate index, and seedling dry matter). The genotype Cubana and two Grand Rapids had higher yields under the tested conditions. Higher seed weights were recorded in 2017. Both genotypes Grand Rapids reached the minimum germination standard established for commercialization (80%). Vanda and AC 5058 showed a better performance for germination rate index and first germination count, while Cinderela had a better seedling dry matter. These varieties were promising for organic cultivation.
