RESUMO:

Floriculture is an economic activity that is expanding in Brazil, in which, in the last year (2021), the sector grew by 15% compared to 2020, even with the embezzlements that occurred due to the pandemic of the new Coronavirus. The cut sunflower (Helianthus annuus L.) is a species with great potential for the floriculture market in the country, since its cultivation is easy to manage and can be a good alternative for income gain for families that live from family farming. Therefore, the objective of the research was to evaluate the performance and adaptation of 12 new sunflower genotypes of Italian origin in the city of Cáceres-MT, through the activities developed by the Flores Para Todos project. The seeds of the 12 sunflower genotypes were sown in trays containing Carolina Soil commercial substrate until germination, in which the emergence count was made and the duration of the phase between sowing and emergence was determined. In the field, a randomized block design (DBC) was implemented, containing two blocks (beds), where each genotype had two replications. The beds were 1 m wide, with the seedlings arranged in four rows with a spacing of 20 cm between rows and 12.5 cm between plants in the row (8 plants per linear meter in the row), which results in a density of 32 plants/m² . Ten plants in the two central rows (five per row) were marked to be evaluated during the developmental cycle until harvest. In them, the number of leaves was counted and the date of the main stages was monitored: visible floral bud, visible flower color and harvest point, and the final number of leaves was counted. At the point of harvest, its total length and the cut of the floral stem at 70 cm were measured and the diameter of the stem at the height of the cut and the diameter of the capitulum were measured and classified according to tortuosity.
