摘要
本文报导了油桐5个品种(无性系)的完全双列交配设计的部分试验结果,分析了各杂交组合产油量的配合力效虚,并估算了遗传力和G·V·C％。1.5个品种产油量的一般配合力效应不显著,但特殊配合力和正反交效应均达到极显著水平,而且正反交效应占绝对优势(G·V·C％=75％),组合和单株的h^2B分别为82.67％和48.82％。2.产油量的优势组合是3×8、3×15,08×0、8×0和3×0,其遗传增益为35.48％,其中最优组合的遗传增益为54.49％。
This article reported part of experimental results of complete two-way cross design of 5 varieteis (clonal) of Tungoiltree (Vernicia fordii), response of combining ability on oil output of every cross was analysed, heritability and percentage of G. V. C. were estimated. 1. Response of general combining ability on oil output of 5 varieties was not notable but special combining ability and reciprocal cross response were remarkable, the reciprocal cross response was absolute predominance (G. V. C.%=75%), h^2B of composition and single plant reached respectively 82.67% and 48.82% 2. Dominance composition for oil output were 3×8, 3×15, 08×0, 8×0 and 3×0, the hereditary gain was 35.48% and that of optimum composition could reach 54.49%.
