摘要
优树选择是林木遗传改良的非常重要的手段,通过福建省高油脂乌桕优良单株的优择及苗期试验,结果显示:对福建省305株候选优树进行测产评定,第一年初选出114株产量达标的优树,第二年初选出产量达标的优树有26株,综合产果量及含油率两个性状指标,共有12棵优良单株入选;对114株初选优树进行一年生苗木子代测定,共11棵优树家系入选,利用综合选择指数对亲代优树进行分类,可将入选的12棵优树分成4大类。
Selection of superior tree is an very important means of tree genetic improvement, through selection of high oil Sapium sebiferum and its seedling test, the yield estimation 305 candidate trees was implemented in Fujian Province, the yield of 114 reached the standard in the first year and that of 26 in second year. 12 superior individual trees were selected according to seed yield and oil ratio. 11 superior families were selected. 12 superior trees could be divided into 4 groups by comprehensive selection index.
