油桐(Aleurites fordii Hemsl)为我国特产的木本油料树种。我国桐油产量占世界的75％以上,出口量占世界总贸易量的30％左右。有千余种工业品用到桐油。油桐分布广,栽培历史悠久,存在着许多地方品种和自然类型。不同品种,类型之间经济性状差异很大。对油桐选种、国内外已进行了大量工作,但对其主要性状的遗传分析至今尚未见报道。
Aleurites fordii Hemsl is a woody oilseed species of our country. China’s tung oil production accounts for more than 75% of the world’s exports account for about 30% of the world’s total trade volume. There are more than a thousand kinds of industrial products used in tung oil. Tung oil widely distributed, cultivation has a long history, there are many local varieties and natural types. Different varieties, types of economic traits vary widely. A great deal of work has been done at home and abroad on the selection of tung tree, but the genetic analysis of its main traits has not been reported yet.
