为了给白粒胡麻品种在生产中的应用提供参考，在长期病圃对16份白粒材料进行抗枯萎病鉴定评价。结果表明通过田间枯死率调查，高抗枯萎病的品种(系)为79073，枯死率为3.14%；中抗枯萎病的品种(系)为QS9、8012-2-3、NY2015，枯死率为7.99%～18.45%。不同生育时期的调查发现，胡麻枯萎病在全生育期均可发病，但在生育后期发病较重，开花期与青果期的发病占比达到全生育期发病总数的70.24%。

In this study，16 white grain cultivars(lines) were identified and evaluated for their resistance to fusarium wilt by long-term disease nursery. This provides reference for the application and extension of high-quality and special white seed cultivars(lines)in flax production. The results showed that 79073 cultivars(lines)with high resistance to fusarium wilt and 3.14 % of wilt rate through field investigation. Three cultivars(lines)with moderate resistance to fusarium wilt were QS9，8012-2-3，NY2015 and the mortality rate was 7.99%～18.45%. At the same time，the incidence of fusarium flax in different growth stages found that fusarium flax could occur in the whole growth stage. However，it is more severe in the late reproductive period. The incidence ratio of flowering and fruit stage reached 70.24% in the whole growth period.
