I. Introduction<\/H1>
\n


\n

Eucalypts are a group of species that are widely planted in many regions in our country (especially in Central and South Vietnam provinces) to supply paper and particle board raw material, mine-props, constructional timber and firewood. These are also main species planted along the roads in rural areas, along rice-field bunds in the Red River Delta in the North and Mekong River Delta in the South.
\n


\n

Results of research and cultivation in many passing years show that of the eucalypt species introduced in our country only some have fast growth and are of high adaptability, note worthy are Eucalyptus urophylla<\/I>, E.camaldulensis<\/I> and E.exserta<\/I>.
\n


\n

Interspecific crossing between these species aimed at creating hybrids of high productivity and adaptability to concrete sites will contribute to meeting the demand for raw material for industries mine-props, constructional timber, firewood and protection forest planting in some regions in our country in contribution to the implementation of the planting of 3 million of hectares of production and protection forests.

According to Martin (1989), there had been up to 1989 over 20 interspecific hybrid combinations, created in the Eucalyptus genus of which the main group consists of E.grandis<\/I> and E.urophylla<\/I> as mother trees. They are E.grandis<\/I> crossed with E.robusta<\/I>, E.camaldulensis<\/I>, E.tereticornis<\/I>, E.saligna<\/I> and E.pellita<\/I>, E.urophylla<\/I> crossed with E.grandis<\/I>, E.pellita<\/I> and E.resinifera<\/I>. A series of hybrid combinations between E.alba<\/I>, E.camaldulensis<\/I>, E.microtheca<\/I>, E.tereticornis<\/I>, E.polycarpa<\/I> and E.torelliana<\/I> were also created in 1991-1999 period in India (Paramathma, Surendran, 2000).<\/p>\n","protected":false},"excerpt":{"rendered":"
