利用显性核不育亚麻的育性稳定、不育株标记性状明显等遗传特点，进行了轮回选择、品种改良、培育新品种等多种利用途径的探讨。选育出产量超对照（内亚二、三号）８．１％～１８．９％的优良品种“内亚四号”；改良了“内亚二号”不抗枯萎病的缺点；创建了两个轮选群体；选育出２０个品系和一大批优异的单株材料。
Utilizing the genetic stability of dominant genic male sterile flax and marked traits of sterile plants, we discussed the utilization of recycle selection, variety improvement and cultivating new varieties. The excellent variety “Neya IV” with a yield of 8.1% ~ 18.9% over the control (Neia II and No.3) was bred; the defect that “Neiya 2” did not resist fusarium wilt was improved; Two rotation groups; bred 20 strains and a large number of excellent single plant material.
