摘要: 利用分别设置在浙江省淳安县姥山林场和福建省邵武市卫闽国有林场的3年生6×6半双列遗传交配设计3代子代测定幼林,对马尾松生长性状的遗传效应及其与环境互作效应进行研究。结果表明:马尾松树高和地径的配合力效应及其配合力与环境互作效应皆达到显著或极显著水平。在遗传效应中,树高在两地点皆以加性基因效应控制为主,显性基因效应次之;而地径在卫闽点主要受加性基因效应控制,在姥山点则主要受显性基因效应控制。在不同环境下,对树高和地径表型影响从大到小依次为环境效应>加性基因效应>显性基因效应与环境互作>显性基因效应>加性基因效应与环境互作。参试性状的一般配合力(GCA)稳定性普遍高于特殊配合力(SCA)稳定性。以树高生长量为选择指标,在2个试验点各初选2个优良亲本和5个优良杂交组合,姥山点和卫闽点优良亲本的遗传增益分别是试验平均的5.61% 8.05%和10.22% 12.98%,是当地优良天然林分子代的45.11% 48.48%和51.84% 55.64%,而优良组合的遗传增益分别是试验平均的3.37% 17.69%和9.35% 25.93%,是当地优良天然林分子代的42.04% 61.72%和50.64% 73.48%。Abstract: Two samples of 3-year-old Pinus massoniana grown in Laoshan forest farm of Zhejiang Province and Weimin State-owned Forest Farm of Fujian Province respectively were used to investigate the genetic effects and the interaction with environment on growth traits in the 6×6 half diallel cross design. The results showed that the combining ability and the interactions of combining ability with environment were significant effective in the height and DBH. The additive gene effects of height played a major role in the two research site. The DBH appeared to be controlled mainly by the additive gene effects in Weimin site, while controlled primarily by the dominance gene effects in Laoshan site. The performance of tree height, DBH and stem volume were controlled mainly by the environment effects and secondly by the additive gene effects and the interactions of dominance gene effect with environment and the dominance gene effects, the interactions of additive gene effect with environment played the weakest role under different environment conditions. The stability of general combining ability(GCA) was significantly higher than that of the specific combining ability(SCA). Based on tree growth index, 2 superior parents and 5 superior combinations were preliminarily selected for the two samples respectively. The gains of superior parents for the two test samples were 5.61%-8.05% and 10.22%-12.98% compared with the mean value, 45.11%-48.48% and 51.84%-55.64% compared with the progeny of the original high-quality stands. The gains of superior combinations were 3.37%-17.69% and 9.35%-25.93% compared with the mean value of the test samples, 42.04%-61.72% and 50.64%-73.48% compared with the progeny of the original high-quality stands.
