This paper is a result of researching the number of lettuce (Lactuca sativa L.) seed per plant in two sowing periods. Ten lettuce varieties for total flower number and the number of flowers per flower head in two sowing periods were compared. Two-factorial trial in random block system with four replication was performed. The correlation of the two researched traits was medium (r=0.706) without significance. Regression coefficient showed the correlation of these traits. Variance analysis showed that variance of genotype was not significant: the other factor, sowing time and interaction (genotype x sowing time) were not significant. The coefficient of phenotype variance was higher than the genetic variance coefficient for both traits.
