摘要: <正>对油桐不同类型的12 个家系作了树体及产量性状的幼成年相关分析,表明家系间存在遗传上的差异,并且遗传力和年度间的重复力较高;主干粗、枝下高两性状1 年生和5 年生有较紧密的遗传相关,树高性状相关不密切;2 年生与3 至6 年生各年的产量呈负向的遗传相关,其余各年度间的遗传相关是正向的,表型相关与其对应。“早丰”类家系在1 年生时就可以进行树体性状的早期选择,2 年生时对结实量进行预测和选择,就有着一定的可靠性;而高产稳产类树体和产量的早期选择需相应推迟1 ~2 a。

Abstract: The correlate analysis on the tree shape and output character in young and adult trees which belong to 12 families of varied types of Tungoiltree has been made.It shows the heritability differs in families,the heritabity and repeatability of year are much higher.There is a much closer correlation in diameter of trunk and height of main branch in the first year with those in the fifth year,but there is less in height of tree.There is a negative correlation in output in the second year with that in the following years,but there is a positive correlation in other factors,and the phenotype is in correspondence with that as stated above.It is reliable on the family of “Zaofong”type to select the tree shape in the first year and output in the second year.The selection of other types with high product and stable product put off 1~2 years.
