摘要
在油茶天然林分中进行群体选择,评选出优良母树,并营造示范林。在此基础上利用个体选择评出33个优株,连续4年进行无性系测定,选育出12个高产优良无性系,亩产油量达51.76kg,各项指标均表现优良。
The systematic selection approach was tried in clonal breeding of oiltea camellia by the following procedures. First, group selection was conducted in natural oiltea stands. Then, dominant seed trees were determined and demonstration plantations were established. Further, individual selection followed, picking out 33 superior trees. Finally, through a 4-year clonal test, 12 superior clones were produced. The oil yield of these clones amounted to as high as 776.4 kg per ha, and their other significant indices proved good.
