Results on trial of newly approved eucalyptus clones in Hoa Binh and Thanh Hoa In recent years, dozens of fast-growing Eucalyptus clones were approved by Ministry of Agricuture and Rural Development as new advanced-technological varieties. However, only some of those clones were planted in a large scale, such as U6 and PN14. In order to put newly approved varieties into large-scale planting, trials of these varieties in major ecological regions of Vietnam should be conducted. Trials of new … [Read more...]

Studying the applicability of the SSR markers in evaluating the growth of the eucalyptus hybrid lines Molecular assisted sellection are increasingly interested because it can shorten the selection time, even selecting in the seedling stage. The molecular markers which linked with the interested traits will be used to evaluate in order to select the superior lines. 14 SSR primer sets were used to evaluate the growth of the Eucalyptus hybrid lines from some of the hybrid combinations. These … [Read more...]
