杉木优树是按表现型进行选择的。表现型是遗传基础和环境条件互相作用的结果。因此,必须进行后代测定,籍以鉴定其遗传品质,以选出一般配合力高的优良个体。后代测定我们用优树自由授粉种子和人工控制授粉的种子。现将几年来工作情况汇报如下。 Cunninghamia lanceolata is phenotypically selected. Phenotype is the result of interaction between genetic basis and environmental conditions. Therefore, offspring measurements must be made to identify their genetic quality and to select good individuals with high general combining power. Progeny Progeny We used the elite trees to pollinate seeds and artificially control pollinated seeds. The work of the past few years are reported below.
