Flaxseed (Linum usitatissimum L.) of the Linaceae family is a crop intended for the 
production of oil, fiber for the tissues production and seeds as a functional food. Flaxseed is 
an alternative to winter crops in southern Brazil because it allows crop rotation, has low cost 
and requires the same equipment used in wheat, soybean and corn. The absence of 
improved cultivars adapted to the region has been a limiting factor in the expansion of the 
area. The objective was to evaluate the performance of golden flaxseed lines selected based 
on the productive components, in the city of Campos Novos (SC). Two groups of lines from 
an area of 25 ha in Zortéa (SC) were evaluated in 2017. The selection of progenies was 
carried with involvement among farmers, technicians and researchers from Epagri and 
UFSC. The experiments (A and B) were carried out in a randomized block design with four 
replications. Each experiment consisted of 19 lines, sown at a spacing of 0.34m between 
rows, the plots were formed by a two-meter row and 200 seeds. Data were submitted to 
analysis of variance by the F test (p<0.05) and means were compared by the Scott-knott test 
(p<0.05). The averages of final stand (FE), number of capsules per plant (NCP) and weight 
of grains per plant (GW), in trials A and B, showed differences statistical. It was observed 
that FE was positively correlated with the increase in grain weight per area (GWA) in tests A 
and B. The correlation of NCP and GW variables was negative in relation to GWA and FE. In 
the test of means on the GWA variable, in trials A and B, there were no significant 
differences in yield. In trial A, the 19 genotypes had an average yield of 2,259.41 kg ha-¹, 
with a range of 779.85 kg with a variation of 1751.20 to 2,531.05 kg ha-¹. In test B, the 
average yield of the 19 genotypes was 2,403.18 kg ha-¹, with a range of 707.37 kg, with a 
variation of 2,102.65 to 2,810.02 kg ha-¹. Even with no statistical differences between the 
genotypes, the yield is higher than the national average of 987.1 kg ha-1
, in the year 2018.
