为了选育油桐(Aleurites fordii Hemsl)良种,我们根据早实、丰产、抗性和适应性强的育种目标,在省内外选择和收集了77个优树,并进行了子代测定,从中筛选出1号、67号、73号等三个优良家系。它们的发枝力,结果枝比率、果实丛生量、含油率等经济性状表现较为优良,历年产量较高。
In order to breed Aleurites fordii Hemsl elite, 77 elite trees were selected and collected within and outside the province based on the breeding objectives of early seed, high yield, resistance and adaptability, and the progenies were selected and screened Out of No. 1, No. 67, No. 73 and other three excellent families. Their delineation, fruiting ratio, fruit clustering, oil content and other economic traits performed well, with a high yield over the years.
