经多年多点试验，已从刚果１２号按实生林中选出热研Ｂ号无性系，该无性系生长迅速，容易扦插繁殖，抗风和抗病虫害能力强，干型通直，用其造林，所得林分林相整齐，高径生长量显著超过实生群体，材积生长量超过实生树２倍以上，且适应性强，适宜在海南省推广种植．
Based on the tests,Reyan B clone has been selected and bred from the seedling plantation of Eucalyptus 12ABL.The clone grows fast,propagates easily and prevents from diseases and insects.In this clone plantation,there are some characteristics of the uniform stand and the straight stem-shape.
