通过对国外引进的150份亚麻种质资源的农艺性状鉴定与聚类分析研究,将其分为4个类群。各个类群具有不同的特点,其中类群Ⅰ表现为株高较高、抗倒伏能力差、出麻率高、产量较高;类群Ⅱ株高较矮、较抗倒伏、出麻率较低、产量较低;类群Ⅲ表现为高抗倒伏、抗白粉病、产量较低;类群Ⅳ株高和产量最高。不同类群在育种中有不同的利用价值,尤其类群Ⅲ和Ⅳ中有高抗及高产材料,具有十分重要的利用价值。
The agronomic traits identification and cluster analysis of 150 flax germplasm resources introduced abroad were divided into 4 groups. Each group had different characteristics, among which, group Ⅰ showed higher plant height, poor lodging resistance, higher hemp yield and higher yield; group Ⅱ had shorter plant height, lower lodging resistance and lower hemp yield, and higher yield Low; group Ⅲ showed high lodging resistance, powdery mildew resistance, lower yield; group Ⅳ plant height and yield the highest. Different taxa have different values of utilization in breeding. In particular, there are highly resistant and high-yielding materials in taxa III and IV, which have very important utilization value.
