油桐(Aleurites Fordii Hemsl)是我国特有的木本油料树种。桐油具有广泛的用途。油桐在我国淮河、秦岭以南各省、区均有栽培。在栽培过程中通常是混合采种,实生繁殖。因此,现有林木之间性状差异比较大,是单产低的重要原因之一。为此,国内研究者对油桐的遗传品质改良做了大量工作,然而迄今尚无多世代改良的报道。
Aleurites Fordii Hemsl is a unique woody oilseed species in our country. Tung oil has a wide range of uses. Tung oil in China Huaihe, Qinling provinces and regions south of the area have cultivated. In the cultivation process is usually mixed seed, reproductive reproduction. Therefore, the existing differences between the traits of trees is relatively large, is one of the important reasons for the low yield. Therefore, a great deal of work has been done by domestic researchers on the improvement of genetic quality of tung tree, but so far there have been no reports of many generations of improvement.
