本项研究以全省群选为基础,经长期定位观测、复选和决选,共选出227株优树,采用大砧嫁接技术建成采穗圃和测定林。经连续4年测定,第一批从25个优良无性系中筛选出“赣无1”号等7个高产优良无性系,其4年亩均产油达64.14kg,最高达92.2kg,其各项性状指标分别超过或达到全国高产无性系评选鉴定标准。与参试无性系亩均产油量比较,入选的7个分别增产41%、18.4%、i 22.79%、66.49%、23.72%、39.67%和51.15%。
Based on the mass group selection in the province, this study selected 227 excellent trees after long-term observation, selection and selection. The large-rooted grafting technique was used to build the scion garden and the measuring forest. After 4 consecutive years of determination, the first batch of 7 high yielding elite clones of “Gan No 1” was screened from 25 elite clones. The yield of the 4-year-old mu was 64.14 kg and the highest was 92.2 kg, Each of its traits exceeded or reached the national high-yield clonal selection criteria. Compared with the average clinker yield per mu of clones, the seven selected ones increased yield by 41%, 18.4%, i 22.79%, 66.49%, 23.72%, 39.67% and 51.15% respectively.
