摘要:
桉属7个种11个种批进行生长和耐冻性的联合选择研究。选出在冷凉地区较有潜力的邓恩桉17913、20665和17922以及本沁桉18788共4个种批，蓄积量14.80～20.93 m3/a?hm2，这为国内冷凉地区发展短轮伐期桉树用材林提供了可供选择的速生、耐冻的种植材料。另外，多雷苷桉虽然生长中等(蓄积量10.03 m3/a?hm2)，但耐冻性好，可以作为进一步选择和杂交育种的备用材料。

Abstract:
Selections were carried out on growth and cold tolerance in 11 Eucalyptus seedlots representing seven species. Three E. dunnii seedlots (17913, 20665 and 17922) and one E. benthamii seedlot (18788) were selected out, being 14.80～20.93 m3/a?hm2 in MAI, which had great potential to be used in the plantation practices in cold and cool regions of China. In addition, E. dorrigoensis performed well in cold tolerance though medially in MAI, which could serve as a sound candidate for further selection and hybridization.
Key words:  Eucalyptus, growth, frost tolerance, selection
