Before the Second World War Latvia was one of the biggest flax exporters in the world. After the Second World War flax growing was not considered important for Latvia. Flax growing areas were gradually reduced. The Latvian flax breeding was stopped in 1970. It was started again in 1992. In this work evaluation of flax accessions of the Latvian origin and the best F10 hybrid lines was done. Statistically valid genotypic differences among studied accessions in agriculturally important traits were found. On the phenotypic level there were correlation among technical length and seed vessel number and positive genotypic correlation among seed vessel number and 1000 seed weight. High negative genotypic correlation was found among technical length and 1000 seed weight. Some hybrids obtained from crosses among local genotypes and best foreign varieties were better in several agriculturally important traits in comparison with the standard variety. Four genotypes were suggested as good for fibre flax breeding and two genotypes for oil flax breeding in Latvian conditions.
