胡麻优良品种的筛选

Screening for Fine Varieties of Linseed

在北纬38°～42°,海拔1 100～1 600 m区域内布设了6个试验点,种植华北区主要推广的10个胡麻品种,用以筛选产量、含油率和α-亚麻酸含量高的胡麻优良品种。经过2年的试验表明,在供试品种间单位面积产量的差异不大,而粗脂肪含量与α-亚麻酸含量的差异较大,品种间平均粗脂肪含量为37.5%～42.9%,平均α-亚麻酸含量为47.9%～60.0%。

In order to screen for high yield,oil content and α-linolenic acid content of linseed varieties,10 linseed varieties form North China are planted in latitude 38°～42°,the elevation of 1 100～1 600 meters area emplaced six pilot sites. The research shows that it has little difference between the per unit area yield varieties, and oil content andα-linolenic have great difference among varieties. The average of fat content between varieties is 37.5%～42.9%,and α-linolenic acid content is 47.9%～60.0%.
