摘要
根据选种目标,从各地优良地方品种中选择,收集了24个优良单株,经连续6年的无性系测定分析,以单株产油量为主要评选指标;结合树体结构,从中评选出77、73、74号3个优良无性系,其历年产量的遗传增益达44％以上。
Twenty-four plus trees from several local varieties were studied over a period of six years.Of them three clones, i.e.No.77, No.73, and No.74 were singled out, considering mainly the oil output of each individual tree and the tree form. The three superior clones have shown an annual gnretic yield gain by 44 per cent.
