【摘要】 本文分析了毛白杨Ｄ测定林三个试验点的４年生林木。通过对１３个无性系的方差、Ｇ×Ｅ互作分析表明，各试验点无性系间存在着极显著差异，各地点间以及无性系与地点交互作用差异也极显著；通过对无性系的稳定性和生长适应性及综合评定，选出４个生产力高的优良无性系可在兰州、武威、白银及相似气候区推广；从分析中看出，这些无性系的生长量值与稳定性和适应性关系是多变的，而且是互相独立的。更多还原

【Abstract】 n 4-year-forest of 3experiment stations of white popfar(D)test forest,through analysis of variace’G×E interaction of 13 clones.Theresult showed that the great difference elists in different clones and diffe-rent experiment stations.The interaction between clones and test stationsis also too,According to the result of analysis and integrated assessmentof the clone stability and the growth adaptability.The 4 highproducedadvanced clones were selected.It can be plant in Lanzhou、Wuwei、Baiyinand similar weather range,It is apparent that the relation between thegrowth and the stability adaptability is variable but independent.更多还原
