CARDOSO, ANTONIO ISMAEL INÁCIO. Yield and quality of carrot seeds from cultivars Brasília and Carandaí. Bragantia [online]. 2000, vol.59, n.1, pp. 77-81. ISSN 1678-4499. http://dx.doi.org/10.1590/S0006-87052000000100012.
The objective of the present work was to evaluate yield and quality of seeds on carrot cultivars Brasília and Carandaí. Four replications of five plants were set out in a randomized complete block design. The roots were planted after 40 days of vernalization at 5 °C and the seed harvesting was in October. Number of umbels, seed yield per plant and per umbel, 1.000 seed mass and germination, according to umbel order, were evaluated. Cultivar Brasilia had higher seed yield per plant (52 g), due to higher yield in secondary umbels (38 g), but not different from Carandaí in primary and tertiary umbels. Differences between cultivars were not observed in the other evaluated characteristics. Primary umbel had greater seed yield (7.5 g per umbel), followed by secondary (3.0 g per umbel) and tertiary was the least productive (0.5 g per umbel). Primary umbel seeds were heavier (2.1 g per 1.000 seeds) than secondary (1.6 g per umbel) and secondary were heavier than tertiary (1.4 g per umbel). Seeds from primary and secondary umbels had better quality than tertiary umbel seeds.
