Correlations in twenty genotypes of linseed (Linum usitatissimurn L.) were used for factor analysis, based on seed yield and five yield contributing traits, through the principal component method. The seed yield was positively associated with other traits, however, significantly only with number of seeds per pod and number of pods per plant. Three factors accounted for 94 percent of the variation. Factor-I included number of branches per plant; Factor-II, number of seeds per pod and Factor-Ill, 1000 seed weight and plant height. Thus, traits related with seed yield were affected by different factors. Number of seeds per pod in Factor-II appeared to be the most important yield component. Direct improvement in this character would improve seed yield potential without affecting other plant characters.
