Resumo
Safflower (Carthamus tinctorius L.) is a species cultivated for more than two millennia
and has been cultivated on all continents. This crop is an alternative for the
production of oil, and for use in food and industry. The seeds of this species have oil
contents that can vary from 35 to 50%. In view of this scenario, the objective of this
study was to evaluate the different safflower genotypes sown in the harvest and offseason, in the municipality of Rondonópolis-MT. The experimental design was a
randomized complete block design, in a plot plot subdivided 7 x 2, corresponding to:
(a) the experimental design was a randomized complete block design in the
experimental area of the Institute of Agrarian and Technological Sciences of the
Federal University of Mato Grosso, Campus of Rondonópolis. Genotypes (PI-
237538; PI-248385; PI-250196; PI-305205; PI-306596; PI-306603; PI-613366) and
sowing times (harvest and off season). Each treatment contained three replicates
and each plot consisted of 5 lines of 4 m length spaced apart by 0.45 m. The data
were submitted to analysis of variance, Tukey test, correlation, adaptability and
stability. The genotypes PI-306596 and PI-237538 were expressed the highest
potential. The sowing done in (December) provides the highest productivity yield of
safflower grains. Safflower production was influenced by variables, height of
flowering plants, number of chapters per plant, dry mass of chapters, mass of a
thousand grains. Genotypes PI-306603, PI-613366 showed high adaptability and
stability in all the methodologies studied.
