摘　　要：株型是反映作物性状重要指标。水稻、玉米、小麦、油菜、大豆等粮油作物在株型育种方面研究比较深入。株型对油用亚麻来说,同样是一个重要综合性状指标,分枝性状是油用亚麻株型主要反映。前人调查油用亚麻分枝性状指标,一般只调查分枝数,而对分枝长短和分枝空间分布状态不做调查和描述,不能反映分枝总体状况。笔者从油用亚麻"分枝层高"和"分枝类型"性状引入必要性、可行性以及在品种资源、新品种选育、栽培技术研究中意义进行了分析论述,对全国油用亚麻区域试验、栽培技术研究中实际应用结果进行了评估,以期引起相关研究者对油用亚麻这一性状研究的重视。Plant type was a reflection of the important crop traits. The study of plant type breeding was in-depth on grain and oil crops such as rapeseed, soybeans, rice, corn and wheat. Plant type was an important trait for oil flax. Branch characters indexes can reflect most with oil flax plant type. Previous researchers researched the oil flax economic indicators for branch characters only commonly investigation branch number, but the branch length and branch space distribution state had no investigation and description, this couldn’t reflect the overall situation. This article analyzed and discussed the introducing oil flax traits“layer height of branch”and“branch type”from the following five aspects： the necessity, feasibility, the variety resources and new variety breeding, and cultivation technology research significance, also evaluated actual application results of the national oil flax regional test, and cultivation techniques research. We expected relevant researchers to pay attention on the study of these traits of oil flax.
