Preliminary Study on a Progeny Trial of Eucalyptus tereticornis

  • Received Date: 1994-11-29
  • The results of a progeny trial of E. tereticornis involved 14 provenances and 100 open-pollinated families at age 32 months in western Guangdong Province showed that the growth differences among 14 provenances were highly significant while the growth differences among families were also highly significant.The most of better families were from QLD provenances 13659,16558,15826, 13544,and from PNG provenance 13398.The poor families were from NSW provenances 13308 and 13319.The volume of the best family Fam-51 from 1 km North of Laura QLD was 4.6 times larger than that of the poorest family Fam-33 from Sirinumu Sogeri PNG. The height growth,DBH,volume,stem form and current survival of E. tereticornis were highly significant and negatively correlated with the latitudeand longitude of its native habitat.The paper identifies 25 promising families suitable forplanting in the west of Guangdong Province.

Abstract: The results of a progeny trial of E. tereticornis involved 14 provenances and 100 open-pollinated families at age 32 months in western Guangdong Province showed that the growth differences among 14 provenances were highly significant while the growth differences among families were also highly significant.The most of better families were from QLD provenances 13659,16558,15826, 13544,and from PNG provenance 13398.The poor families were from NSW provenances 13308 and 13319.The volume of the best family Fam-51 from 1 km North of Laura QLD was 4.6 times larger than that of the poorest family Fam-33 from Sirinumu Sogeri PNG. The height growth,DBH,volume,stem form and current survival of E. tereticornis were highly significant and negatively correlated with the latitudeand longitude of its native habitat.The paper identifies 25 promising families suitable forplanting in the west of Guangdong Province.
