直干桉全同胞家系生长性状遗传稳定性分析

A Hereditary Stability Analysis of Growth Characteristics of Eucalyptus maidenii Full-Sib Family

    摘要
  • 摘要: 直干桉生长性状全同胞家系间存在显著的差异;而在年度间差异不显著,年度和组合间的交互作用未达到显著水平,说明直干桉年度间稳定性较好;地点间差异、地点与家系间交互作用都达到显著水平。胸径受遗传控制较弱,而树高和材积受弱度-中度遗传控制。将参试的17个家系按丰产性和稳定性分成4类,选出速生丰产的4个家系,推广用于生产。

     

    Abstract: There are significant differences between full-sib family of Eucalyptus maidenii and site as well interaction between site and family.No significant difference between year and the interaction with year and combination has been found,indicating that there are strong stability among years.The result shows that DBH is controlled by week genetics and height and volume are controlled by week-medium genetics.
