摘 要 ：本文用扩展三重测交设计研究了甘蓝型油菜芥酸及其他脂肪酸含量的遗传。结果表明,芥酸的上位性效应不显著,主要受加性效应控制,显性作用较小。显性方向为正,一级统计量分析不显著,二级统计量分析达显著水平。方差分量 D,H 和 F 的估值分别为358.15—362.22,8.74—18.00和51.77—53.26。平均显性度为0.1553—0.2242,优势比为0.
Abstract:The genetic parameters of erucic acid were estimated by the augmented triple testcross(aTTC)analysis developed by the senior author(1988).The results indicated that theerucic acid content had no significant epistasis and was governed by genes acting in anadditive manner.The dominance effects were le
