Abstract: Dominant nuclear sterile flax has some genetic properties such as stable sterility and obvious marker on sterile plants. Using these,a series of researches were conducted,e. g. recurrent selection varietal improvement and breeding of new varieties. Also,a series of breeding plans were developed and put into practices. "Neiya 4",which is 8.9-18.9%heigher in yield than the control group,was bred."Neiya 2",which was susceptible to wile disease originally,was improved. By now,two recurrent selection groups have been developed,20 strains as well as a lot of excellent single-plant have been bred and selected.

Key words: Flax, Dominant nuclear sterile, Utilization
