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 Zort??a (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&lt0.05) and means were compared by the Scott-knott test  (p&lt0.05). 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-??,  with a range of 779.85 kg with a variation of 1751.20 to 2,531.05 kg ha-??. In test B, the  average yield of the 19 genotypes was 2,403.18 kg ha-??, with a range of 707.37 kg, with a  variation of 2,102.65 to 2,810.02 kg ha-??. 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.  aLinnum usitatissimum L  asuperior lines  ayield1 aFIOREZE, A.
