【摘要】 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。更多还原

【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.更多还原
